SIEMENS SENTRON ACCESSORY
Undervoltage release accessory operating at 380–400 V AC, 50/60 Hz, for compatible Siemens SENTRON 3VA1 and 3VA20–26 molded case circuit breakers (MCCBs).
Part No.: 3VA9908-0BB26 380–400 V AC
The Siemens 3VA9908-0BB26 undervoltage release is an electrical accessory designed for specified compatible Siemens SENTRON 3VA1 and 3VA20–26 molded case circuit breakers (MCCBs). It is rated for a control voltage of 380–400 V AC at 50/60 Hz.
An undervoltage release is designed to respond when its supply voltage falls below the specified operating level. Depending on the breaker configuration and release characteristics, it can cause the associated circuit breaker to trip or prevent it from closing when the required control voltage is unavailable.
This accessory is relevant to electrical panel manufacturers, OEMs, industrial maintenance teams, system integrators, electrical contractors and replacement-parts buyers who require a compatible undervoltage protection accessory for a Siemens SENTRON circuit breaker.
Before ordering, verify the exact breaker model, accessory mounting arrangement, control voltage and manufacturer compatibility documentation to ensure the correct selection.
