It's the remote-trip coil that lets a PLC, safety relay, or E-stop circuit open the breaker from a distance — common on machinery with a guarded access door or an emergency-off chain that needs to kill power without someone running to the panel. Rated for 208–277 V AC at 50/60 Hz, it draws up to 720 VA apparent power on energization. Physically it's a compact add-on: 65.1 mm tall, 21.7 mm wide, 31.2 mm deep. That 21.7 mm width means it occupies roughly one modular unit on a DIN rail — important when you're counting slots in a crowded enclosure. The stripped length is 10 mm (0.4 in) for the screw terminals, standard for this class of accessory. ## Compatibility and compliance The 3VA9988-0BA23 is designed specifically for SENTRON 3VA breakers in the 3VA10 through 3VA14 and 3VA20 through 3VA24 frame sizes. It clips into the accessory slot on the breaker's side — no separate DIN-rail mount, no extra wiring space needed beyond the breaker's own footprint.","metaTitle":"Siemens 3VA9988-0BA23 Shunt Trip, 208-277 VAC, SENTRON","metaDescription":"Siemens SENTRON 3VA9988-0BA23 shunt trip accessory for 3VA10–3VA24 breakers. 208–277 VAC 50/60 Hz, 4 kV surge.
