The MN undervoltage release is intended for use with Compact NS 630b to Compact NS 3200 devices. It operates within a voltage range of 200VDC to 250VDC or 200VAC to 250VAC at 50/60Hz. This auxiliary component is essential for emergency shutdown or remote opening functions. It triggers the circuit breaker to open when the control voltage drops below 35% of its rated voltage (Un), ensuring safe operation in critical situations.

Complying with the IEC 60947-2 standard, this undervoltage release is compatible with both the ComPacT NS630b...1600 and ComPacT NS1600b...3200 models. The device features a fixed mounting mode and has a response time of 90 ms ± 5% for the Compact NS630b...1600 and Compact NS1600b...3200 series. With a supply holding power of 4.5 VA, it provides reliable operation within its specified parameters.
