It is fitted with the ETU860M electronic trip unit providing LSIG protection (long-time, short-time, instantaneous, ground fault) and a fixed In=500A rating with overload protection adjustable Ir=200A...500A. Short-circuit protection is set via Isd=1.2..15 x In and Ii=3..15 x In. Ground-fault protection can be switched off, with Ig adjustable 0.2...1 x In and time delay tg=0.05-0.8s. The breaker includes an undervoltage release rated 24 V DC, one auxiliary switch changeover H, one trip alarm switch changeover, and one electrical alarm switch HQ. ## Deployment Context The 110 kA @ 415 V SCCR provides substantial fault-current headroom for industrial distribution and motor protection applications where selectivity and coordination are critical. The integrated undervoltage release (24 V DC) and auxiliary/trip alarm switches make it suited for safety circuits requiring undervoltage protection and remote status indication — typical in process lines and critical motor feeders.","metaTitle":"Siemens 3VA2450-7MQ32-0BK0 Circuit Breaker, 110kA @ 415V, 50","metaDescription":"Siemens 3VA2450-7MQ32-0BK0 IEC frame 630, class C, Icu=110kA @ 415V, 3-pole, ETU860M LSIG, In=500A, 24 V DC undervoltage release.
