Schurter FMAC NEO, FMAD NEO 3-phase Block Filters

3-Phase Block Filters for Machine Applications
• For machine applications according to IEC 60204-1
• Compact design with small footprint
• 1-stage filter with high efficiency

Schurter is expanding the successful FMAC NEO and FMAD NEO 3-phase filter families with new variants for machine applications. The new filters meet the requirements of machine safety according to IEC 60204-1. They are suitable for 3-phase or 3-phase-with-neutral conductor applications at rated currents from 16 to 230 A.

The FMAC NEO and FMAD NEO single-stage block filters have a particularly compact design with a small footprint and high performance at the same time. They are suitable for industrial or energy applications such as EV fast charging stations or battery storage.

IEC 60204-1: Machine Safety
Any machine or equipment that is to be brought onto the market in the EU and associated countries must bear a CE marking issued by the manufacturer himself. With this marking, the manufacturer guarantees that his product complies to all applicable legal and technical requirements. Minimum standards with regard to safety and occupational health requirements are defined in Europe by the Machinery Directive 2006/42/EC and the Low Voltage Directive 2014/35/EU.

The details for implementation are defined in separate specifications, known as harmonizing standards. One of these harmonizing standards is IEC 60204-1, which applies to electrical, electronic and programmable electronic equipment as well as to groups of networked machines, including control cabinet construction.

New Filter Variants
The new filter versions meet the requirements of this standard IEC 60204-1. The filters have a short discharge time of the capacitors, so that they have a touchable residual voltage of <60 V in 1 or max. 2 seconds after disconnecting the voltage. Further, the insulation value between phases and ground is at least 1 MΩ thanks to larger resistors. The filters are designed for currents from 16 to 230 A at an ambient temperature of 50 °C.

All family members have ENEC and cURus approvals and are recommended for applications up to 520 VAC. The standard variants are designed for industrial applications with leakage currents <13 mA. Special variants with leakage currents <3 mA are available for particularly leakage-critical applications.
