That's high-interrupting capability for systems with high fault current — think large transformer secondaries or industrial distribution close to the utility service entrance. ## Auxiliary and shunt trip configuration That means remote tripping and status feedback are built in — no field retrofit of the accessory stack. The shunt trip is wired to a remote pushbutton or safety relay; the alarm switch signals the PLC when the breaker has tripped on fault. Listed as current production.","metaTitle":"Siemens 3VA1580-5EF32-0KH0 SENTRON MCCB, 800 A, 3-Pole, 187","metaDescription":"Siemens SENTRON 3VA1580-5EF32-0KH0 molded case circuit breaker, 800 A, 3-pole, 187 kA interrupting at 240 V.
