Product details

The Siemens 3VA9988-0BA20 is a shunt trip (auxiliary release) accessory for the SENTRON 3VA10 through 3VA14 and 3VA20 through 3VA24 molded case circuit breaker families.

The shunt trip measures 31.2 mm deep, 21.7 mm wide, and 65.1 mm high. That depth is shallow enough to clear most standard enclosure backplates and DIN-rail-mounted breaker footprints; the 21.7 mm width matches the accessory slot width on the 3VA breaker frame, so it snaps into the three accessory slots on the breaker side without eating extra DIN space.
