Product Description:

The 07.U5.B0B-1010 is an electromagnetic interference suppression module manufactured by KEB within the Combiline EMC Filters series. Installed between a single-phase drive and the mains supply, this filter attenuates conducted noise so that variable-speed inverters can meet CE emission limits without disturbing nearby sensors or control electronics. It is sized for systems that draw up to 0.75 kW of motor power and fits into KEB housing type B enclosures used in small automation panels.

The filter accepts power from a single-phase line and is designed for a nominal line voltage of 230 V AC. It can withstand up to 264 V without dielectric breakdown, preserving insulation integrity during voltage peaks. Its input network supports utility frequencies of 50/60 Hz, allowing use in regions with either frequency. The unit is matched to drives that feed motors rated at 0.75 kW; pairing it with equipment within this range maintains common-mode attenuation and prevents thermal overload. Terminals accept conductors up to 4 mm². The steel chassis measures 88 mm wide, 40 mm deep, and 249 mm high, allowing rail mounting inside shallow cabinets while leaving clearance for airflow.

Electromagnetic compliance is classified as C1, allowing the filter to be installed directly at the mains input when equipment must satisfy stringent residential emission requirements. During operation, the internal capacitors produce only 3.4 mA of leakage current, reducing the risk of nuisance ground-fault trips on sensitive residual-current devices. Core and resistor losses generate only 5 W of heat, adding little thermal load inside the cabinet. When the filter is connected to an inverter, the maximum permissible shielded motor cable length is 10 m; keeping the lead within this limit preserves the filter’s attenuation performance and limits reflected-wave stress on the motor insulation.
