The trip indicator is built in, and the voltage trigger (shunt trip) is present; undervoltage release and phase failure detection are not fitted on this variant.","metaTitle":"Siemens 3VA1150-4EF32-0HH0 SENTRON MCCB, 50 A, 3-Pole, 121 k","metaDescription":"Siemens 3VA1150-4EF32-0HH0 SENTRON molded case circuit breaker. 50 A rated, 3-pole line protection with TM240 release. 121 kA at 240 V.
