The release measures 25.7 mm wide, 65.1 mm high, and 28.8 mm deep. It mounts inside the 3VM breaker accessory slot — no additional DIN-rail space is consumed. The stripped length for wiring is 10 mm (0.4 in). Three accessory slots are available on the 3VM frame; this release occupies one. Verify slot compatibility with any other auxiliary devices (shunt trip, alarm contacts) already installed or planned, as the mechanical interlock within the breaker limits which combinations fit.","metaTitle":"Siemens 3VM9908-0BB25 SENTRON Undervoltage Release, 208-230V","metaDescription":"Siemens SENTRON 3VM9908-0BB25 undervoltage release for 3VM breakers to 630A. 208-230V AC 50/60Hz, 4kV surge, 2VA.
