Product details

The Siemens 3VM9908-0BB20 is an undervoltage release accessory designed for the 3VM10 through 3VM14 molded-case circuit breaker family. That's a standard fit for panel builders wiring undervoltage protection into a distribution board — the release mounts directly into the breaker's accessory slot, no extra DIN rail space needed.
