Schurter has a long tradition with circuit breakers. In addition to their thermal release (bimetal), the classic TA35 and TA36 are now optionally equipped with an additional magnetic module, which promises reliable protection within milliseconds in the event of very high overcurrent (short circuit).
Thermal Circuit Breakers
Circuit breakers are usually designed according to the thermal principle with a bimetal. If a defined temperature is exceeded due to overcurrent, the electric circuit is interrupted. Once the bimetal cooled down, the appliance is ready for use again. However, if a short circuit occurs, the bimetal cannot react fast enough. For this reason, thermal circuit breakers are usually combined with a fuse.
Additional Magnetic Module
Schurter is now upgrading its 2-pole classic TA35 and TA36 models with an additional, optional magnetic module. From now on, no additional fuse is required when using a thermal-magnetic type. Depending on the application, the magnetic modules are available either with a slow or a fast acting characteristic.
Both models are designed for snap-in mounting and with finely graduated rated currents. A variety of colours and lighting options make the designer's choice easier. The Schurter TA35 has a more classic style, while its TA36 counterpart comes in a more modern design. A circuit breaker with a short circuit protection is mainly meant for applications, where a full protection on the primary side is required.

Schurter launches a new 3-phase filter series for DIN rail mounting. Thanks to the slim housing (44 mm), it takes up very little space on the mounting rail in the control cabinet. The single-stage filter is available with standard or high attenuation. A metal base plate ensures an excellent ground connection to the rail.
Space is almost always at a premium in control cabinets for industrial applications in the 3-phase range (e.g. motor drives, control systems). Schurter addresses this problem with a complete new filter design that is just 44 mm in width. The new, single-stage filter series is constructed with a printed circuit board in a plastic housing. It has screw terminals for the three phases and a terminal on the metal base plate for the earth connection.
Standard and High Performance Versions
In the standard version with a ferrite core, the new filters already offer very impressive attenuation behavior. The high performance versions withn nanocrystalline cores achieve up to 8 dB more attenuation.
Low Leakage Currents
The new filter family has particularly low leakage currents of just 1.3 mA. This applies to all versions!
Applications
All versions can be used from -40 °C to 100 °C. The filters are designed for currents from 3 A to 32 A at a maximum of 520 VAC in accordance with IEC and UL standards. They feature ENEC and cURus approval and are suitable for applications in accordance with IEC 62368-1. FPAC rail filters are recommended for devices with high EMC loads (switching power supplies, converters, etc.).
Typical areas of application are therefore industrial or machine control systems, but the highperformance, slimline filters are also ideal for laboratory, telecom and IT devices.

400 VDC Connector According to IEC TS
After launching the first 400 VDC connectors (GP21 and GS21) in accordance with IEC TS 62735, Schurter is now adding models GC21 and GH21/GI21 on the device side - of course IECcompliant. From the network to the device: The Schurter 400 VDC family is the first DC connector solution available worldwide to be complete according to IEC TS.
With the GP21 and GS21 connectors, Schurter launched the world's first DC connector systems standardized according to IEC TS 62735-1 for efficient power distribution in data centers, for power distribution strips and UPS applications back in 2019.
The GH21 and GI21 appliance Inlets are brand new. The GI21 model is designed for pure DC operation, while the GH21 is a hybrid version and can therefore accept both AC and DC current. SCHURTER also offers the rewireable GC21 Connector to match the appliance Inlets. A cord retention system developed from scratch ensures safe operation in everyday use. All three new products are made from a bio-based plastic (Green Plastic).
The Advantages of DC
With a pure DC supply, cost-intensive and failure-prone transformations and conversions, including their components, are completely eliminated. Operational reliability increases with improved efficiency. And climate-friendly technologies that generate direct current are becoming established in energy generation.
IEC TS 62735-1 / IEC TS 63236
Due to its properties, the standards for direct current (2.6 kW) require a more complex connector connection design as DC arcs must be avoided when disconnecting the supply. Another highlight is the extended temperature range of the connector pins from -5 °C to +105 °C.
Matching Cables
Under the designation SPC1, Schurter now also offers suitable, customized DC power cables for all connection options on request.

IP54 In Plugged State with the Dedicated Power Cord
Following the successful launch of the two power entry modules DG11 and DG12 with increased IP protection, Schurter now also offers both models in variants for protection class II applications and in white as well as black.
Protection against dirt particles and moisture is becoming increasingly important. With the DG11 and DG12 product types and the corresponding V-Lock mains cable, Schurter launched an IP54 device connection that was immediately very well accepted. An IP54 value in the plugged-in state in accordance with IEC 60529 offers excellent protection against dust particles and is also splash-proof.
New Variants for Protection Class II
The existing variants of DG11 and DG12 were designed exclusively as 3-pole versions for protection class I applications. There are now 2-pole variants which explicitly meet the higher requirements of protection class II. Of course, this also applies to the associated V-Lock mains connection cable for cord retention.
Special Sealing Elements
The appliance inlet as well as the connector of the V-Lock power cord have been equipped with special sealing elements to achieve this really high IP protection.
Black or White
In response to multiple customer requests, Schurter now offers the two power entry modules DG11 and DG12 in white as well as the most commonly used black.
Application Areas
Wherever dirt, dust particles or splash water may occur, the new Schurter technology is the perfect choice. This may be the case in harsh working environments in industry. In the medical field, a higher IP protection rating is mandatory. This is simply due to the necessity of cleaning and disinfecting medical equipment on a regular basis, and even sterilizing it if required. The food processing industry has very similar requirements.

Single Phase Block Filter
Schurter extends the successful FMAB NEO single phase filter family with new highperformance versions for demanding applications. The new filter series is available in standard and medical versions for a rated current range from 1 A to 30 A with quick connect terminals.
Compact device designs combined with high energy efficiency in electronic devices lead to higher electromagnetic interferences. Components are placed closer together and powerful semiconductors switch at a high clock rate. The new FMAB NEO HP filter series is ideally suited for such demanding applications. Thanks to high quality core materials, they achieve very high attenuation in a compact design.
High-Performance Versions:
The new versions provide very high symmetrical attenuation (design N). In the low and mid frequency range, asymmetric attenuation has been increased as well by employing new high-quality core materials. Overall, this results in a very high filter performance, which is otherwise only achieved by larger filters.
Due to the same size, the standard FMAB NEO Design N filter can be easily replaced with the new high-performance filter when the EMC measurement results require it.
Applications:
The new filter variants are ideally suited for demanding applications such as laboratory and medical
equipment. They also work well in many industrial, telecom and energy applications.
Approvals:
The new variants of the FMAB NEO single-stage filter family are available with rated currents from 1 A to
30 A at a maximum of 250 VAC. They are suitable for applications in the temperature range -40 °C to 100
°C and have ENEC and cURus approvals

IEC C14 Appliance Inlet with High-Performance Filter
For applications that require particularly high interference immunity, Schurter is launching the new high-performance filters of the 5124 series. With identical dimensions to the proven 5120 and 5123 series, both symmetrical and asymmetrical interference signals can be attenuated even better with the 5124 series, thanks to the use of high-performance components.
The 5124 series combines an IEC C14 appliance inlet with a high-performance mains filter. Thanks to a wide metal flange, the housing makes contact over a large area, which guarantees an optimal filter and shielding effect.
High-Performance Filter:
The exclusive chokes with high-permeable toroidal cores of the 5124 series have an inductance that is many times higher than that of the standard 5120 series. This results in an attenuation of asymmetrical interference signals that is around 10 dB higher. Massively enlarged X-capacitors help gainst symmetrical interference. Despite significantly larger components, the dimensions of the 5124 predecessor’s series have been retained.
Identical Dimensions
The 5124 series is available in standard or medical versions. It makes sense to use it where a particularly high attenuation is necessary and the filter effect of a 5120 or even 5123 series is no longer sufficient. Thanks to identical dimensions, the optimal series can be selected - depending on the interference level - without any design changes. The appliance filters are, of course, equipped with the well-proven V-Lock cord retention system.
Performance and Approvals
The 5124 series is certified for currents up to 10 A/250 VAC according to IEC and 15 A according to UL/CSA at 125/250 VAC. It features ENEC, CQC as well as cURus approvals.
