It's built around the ETU310M trip unit, set for a rated current In=400 A, and configured for starter protection — meaning it handles short-circuit protection (adjustable Ii=3...15 x In) but omits overload protection, leaving that to an external overload relay. The nut keeper kit helps secure the busbar connections, which is a small detail that saves time during assembly. The shunt trip occupies the left accessory slot — verify clearance if you're also fitting an auxiliary switch or alarm contact on the right side.","metaTitle":"Siemens 3VA2440-7MS32-0JA0 Circuit Breaker, 110 kA @ 415 V,","metaDescription":"Siemens 3VA2440-7MS32-0JA0 IEC frame 630 circuit breaker, breaking capacity class C, Icu=110 kA @ 415 V, 3-pole, ETU310M trip unit, 400 A rated, shunt trip left 110-127 V AC/DC.
