It's built around the ETU860m trip unit for motor protection, providing LSIG (long-time, short-time, instantaneous, ground-fault) protection curves. Rated In of 400 A, with overload protection adjustable from 160 to 400 A and short-circuit protection from 1.2 to 15 times In. Ground-fault is switchable from 0.2 to 1 times In with a time delay of 0.05 to 0.8 seconds. Designed for busbar connection in panel or enclosure builds. The ETU860m unit supports communication-ready accessories for integration into higher-level control systems.","metaTitle":"Siemens 3VA2440-7MQ32-0KH0 Circuit Breaker, 400A, Icu=110kA","metaDescription":"Siemens 3VA2440-7MQ32-0KH0 IEC frame 630 circuit breaker, 110kA breaking capacity @ 415V, ETU860m LSIG motor protection, In=400A.
