Schurter expands its wide range of power entry modules to include versions, without ground pin, for use in Protection Class II double-insulated applications. The 5145 power entry module is already popular for use in Protection Class I equipment, due to its circuit breaker and EMC filter functions integrated into one compact package. The new Protection Class II version is perfectly suited for medical equipment used at home where the medical standard prescribes the use of Protection Class II design.

The new 5145 Class II version is according to IEC 60320-1, style C18. It is particularly well suited for use in medical equipment according to the IEC standard 60601-1-11, which outlines additional safety measures specific to medical equipment intended for use in the home. There is increasing demand for such equipment as populations around the world age and healthcare costs continue to rise.

Protection Class II equipment, in contrast to Protection Class I equipment, generally has no metal case. This category of equipment is called double insulated, and requires higher safety levels for energized components relative to exposed surfaces. The 5145 Class II power entry module provides double insulation between energized components and exposed parts. This reinforced insulation is tested with a voltage of 4000 VDC between the energized conductor (L) and the neutral conductor (N) relative to the filter case.

The EMC filter is available in medical and low leakage, M5, versions. This integrated filter at the power input provides highly effective interference suppression, which results in optimized electromagnetic compatibility. Current ratings range from 1-10 A at 250 VAC. Versions with quick-connect or solder terminals are available.

The 5145 Class I and Class II are ENEC and cURus approved. They are suited for use in equipment according to IEC 60950, IEC 60601-1, in addition to IEC 60601-1-11.

With the new FUS fuseholder, Schurter is building on its successful FUL series for high-performance applications and presents the first dust and water-proof fuseholder with ingress degree of protection IP67 especially for rough applications.  The snap-in fuseholder series guarantees fast and tool-free assembly.   The carrier is available in both versions with slot and fingergrip and can accommodate fuse sizes 5 x 20 mm or 6.3 x 32 mm.

Thanks to the high IP67 degree of dust and water protection, the FUS series fuseholders can be used wherever high-performance applications are exposed to potentially adverse environmental influences, such as outdoor applications or in the oil and chemical industry, marine, laboratories and mining. In addition, the FUS series fuseholders are also used where the highest ingress protection against liquid and particles is required, as for instance in medical and food production equipment.

Made of halogen-free plastic, the side metal snap brackets act as heat dissipaters and are designed for fast snap-in mounting. Wires are terminated with quick-connect or solder connections. The newly styled fuse carriers accept 5 x 20 mm or 6.3 x 32 mm fuses, and provide slot or fingergrip removal for fuse replacement.

The FUS series already complies with the increased glow-wire material requirements outlined in the new IEC 60127-6 and IEC 60335-1 standards developed for unattended devices in use.  The FUS fuseholders are characterized by a particularly high-quality design and a good price / performance ratio.

Technical Data
• Fuse holder according to IEC 60127-6 / UL 4248-1
• Rated specifications: IEC 16A @ 500 VAC (4 watt) / UL 32A @ 600 VAC / VDC
• Quick-connect connections 6.3 x 0.8 mm or solder connections
• Ambient temperature: -40 ° C to + 85 ° C
• Complies with the requirements of IEC 60335-1 for unattended devices in operation. This includes the stringent glow wire requirements according to IEC 60695-2-12 and -13

Applications
Equipment exposed to harsh industrial environments or the outdoors, measurement, laboratory and medical equipment, marine, dairy and food industries, robotics, controls in mining and underground.

Motor drive output filters protect motor windings against excessive voltage peaks and
inadmissible voltage pulse rise times generated by the inverter PWM output voltage. Dv/dt filters are
required to fulfill the IEC 60034-17/-25 standards defining the limits for IEC-and NEMA AC-motors
and prolonging their life times.

Schaffner, the international leader in the fields of electromagnetic compatibility, power quality and motor drive output filters, introduces the new FN 5060 HV standard dv/dt filter series for 690/600 VAC motor applications. These innovative filters are designed according to Schaffner’s patented concept which enables dv/dt filter damping performance without using resistors or capacitors. This simplifies the installation, saves mounting space and is a reliable long life time solution.

The new filters are designed to offer minimum power loss, low voltage drop and thus help to maximize the system efficiency.

Several industries can benefit from the use of the new 690/600 VAC dv/dt filter such as the chemical, cement, metal, oil and gas, mining, applications in buildings and infrastructure environments (pumps, fans, HVAC) and other industries.

Not only to be used in areas where pumps and fans are controlled by drives with short motor cables, the dv/dt filters from Schaffner are also recommended to be used for applications with frequent braking, danger of flash-over voltage and motors running at high temperature.

New and existing motors and installations will benefit from a longer life time and a continuous long lasting operation, if such dv/dt filters are used with variable speed drives.

The standard 690/600 VAC filter series are available with current ratings from 16 A to 1’200 A. Higher or other ratings can be engineered and delivered on demand.

All models are CE, UL, CSA and ENEC approved and RoHS compliant.
