Ideally suited to protect against overcurrent and short circuit of equipment in telecommunications, process control and other industrial applications where sophisticated equipment requires a high precision performance.
A latching type bimetal is combined with a magnetic coil to ensure protection and genuine physical contact isolation. This provides the joint benefits of delayed operation for low level overcurrent protection and fast magnetic action of higher value short circuits, disconnecting the faulty circuit within milliseconds.

E-T-A not only offers electronic overcurrent protection and thermal or thermal-magnetic circuit breakers, but another type of protection: magnetic and hydraulic-magnetic circuit breakers. What characterises these devices and in which applications are they used?
Circuit breakers and protectors with magnetic or hydraulic-magnetic trip principle are extremely fast and ensure genuine physical isolation. In the event of a short circuit, the magnetic trip mechanism disconnects a defective circuit almost without delay. The circuit is disconnected even at low overloads. The
hydraulic-magnetic trip principle provides an intentional delay in the overload range. You can choose from a wide range of device versions.
The 808 version is a single-pole, polarised circuit breaker with magnetic fast trip mechanism. An uncomplicated switching system ensures eliable disconnection even for the smallest overcurrents. The device can also be used for impulse tripping. The compact design and the fast reaction time are specifically suitable for PCB mounting to protect sensitive electronic components installed there. The device is available with fixed current ratings from 0.01 A to 5 A, which makes this circuit protector highly suitable for fragile loads. Another quality feature is its low temperature sensitivity. Thanks to its extremely compact design of only 30 x 20 x 10 mm (H x W x D) when installed, the 808 version can be mounted on virtually any PCB.
E-T-A’s 8335 circuit breakers for equipment protection are available as single- or multi-pole version with magnetic or hydraulic-magnetic trip principle. They provide toggle actuation, front panel mounting, different characteristic curves and optional auxiliary contacts. The precise switching mechanism ensures reliable disconnection through an independent tripfree mechanism even for the smallest overcurrents.
Like all magnetic devices, they feature low temperature sensitivity at rated load. They are available with a rated current range from 1 A to 50 A and have a very compact design. They are suitable for AC and DC voltages.
The 8335 devices offer economic overcurrent protection for telecommunication applications in the Economy Power-D-Box®. This a a compact power distribution system with only two height units (HU). The redundantly designed rack can be customised with plug-in type magnetic or hydraulic-magnetic 8335 or 8340 circuit breakers.
This product group is very attractive - not only because of the already mentioned benefits of the hydraulic-magnetic circuit breakers - but also because of its many mounting options. Type 8340 and 8340-F devices are available with flange or snap-on mounting. This design version is suitable for the use in the telecommunications / datacom industry. In industrial applications, however, DIN rails are more commonly used. This area is covered by the 8340-T version. The users here appreciate the 8340-T specifically because of its integral auxiliary contacts and the wide temperature range of -40 °C to +85 °C. The 8340-G version is mounted via threadneck. They are normally used e.g. in rail vehicle applications.
When you need a device with many different approvals, the 8345 is the device of choice. With a slim design of only 19 mm, the device can carry rated currents of up to 125 A, which is more than any other device of this product class. It is available with instantaneous, extremely fast or very slow trip curve. It can be extended with additional module options for signalling or remote trip. Thanks to its international approvals, this device can be used in telecommunication applications worldwide and protects the digitisation hardware against damage caused by overcurrents.

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.

Thermal circuit breakers (circuit protectors, resettable fuses, circuit breakers for equipment protection) are ideally suited to overload protection of motors, transformers, magnetic valves, on-board electrical systems and low voltage lines.
The trip time of thermal circuit breakers depends on the height and of the duration of the overload current and the ambient temperature. With higher current ratings, the bimetal or hot wire is heated up until the defined trip time is reached and the device ensures genuine physical isolation of the contacts.

The REX12D intelligent system is ideally adapted to the requirements of machine construction and process control. The compact and modular design, the innovative connection technology and the great number of different devices provide a competitive edge over standard solutions to protect your DC 24 V power distribution.
By extending the functional scope of the REX12D system you are free to decide where to set your focus.
In the standard version, the EM12D-TIO supply module communicates with now 32 channels instead of 16 channels. The status of the channels is transmitted to the superordinate IO link master.
The extended version sets the focus on the recording of measuring values and on the analysis of these measuring data of 16 channels. By means of a cyclical transmission of the load currents, changes in the current consumption of individual loads can quickly be detected. This allows efficient control and maintenance and significantly cuts downtimes.
