Breaking capacity is the headline here: 330 kA at 240 V AC, 242 kA at 415 V and 440 V, and 52.5 kA at 690 V. The ETU350M electronic trip unit handles the protection curve. It includes phase failure detection, so a lost phase on a motor circuit trips the breaker rather than letting the motor single-phase and burn. The shunt trip (STL) auxiliary release lets a remote signal or safety circuit force the breaker open independently of the trip unit. This MCCB measures 248 mm high by 138 mm wide by 110 mm deep — a standard 3-pole frame size for the 3VA2 series. It mounts via screw terminals to a backplate or mounting plate inside an enclosure; no DIN-rail clip on this class of breaker. The IP40 front protection means it's suitable for indoor panel installation where tools are required to access live parts. That gives you four discrete signals for status feedback — breaker open/closed, trip event, and an electrical alarm contact for remote annunciation. It lives in industrial switchboards, motor control centers, and distribution panels where a 500 A feeder or large motor branch needs electronic trip protection with high fault-interrupting capability. No undervoltage release, no ground fault monitoring, and no communication function on this variant — it's a straightforward power breaker with shunt trip and auxiliary contacts.","metaTitle":"Siemens 3VA2450-7MN32-0HL0 SENTRON MCCB, 500 A, 330 kA","metaDescription":"Siemens 3VA2450-7MN32-0HL0 SENTRON molded case circuit breaker, 500 A rated, 330 kA at 240 V, motor protection with ETU350M release.
