The ETU310M is a microprocessor-based trip unit; here it is set for short-circuit protection only (Ii adjustable 3...15 x In), with no overload protection function, so the breaker relies on an upstream or separate overload relay for thermal protection of the connected load. ## Included accessories and integration notes This order code includes an undervoltage release rated 208-230 V AC 50/60 Hz, a nut keeper kit, and one auxiliary switch (changeover H contact). The auxiliary switch provides a remote status signal (open/closed) to a PLC or indicator lamp. The nut keeper kit secures the breaker in the panel; verify gland-plate clearance for the 630 A frame size before mounting.","metaTitle":"Siemens 3VA2450-7MS32-0DK0 Circuit Breaker, 110kA @ 415V","metaDescription":"Siemens 3VA2450-7MS32-0DK0 IEC frame 630 circuit breaker, breaking capacity class C Icu=110kA @ 415V, 3-pole, In=500A, ETU310M trip unit, undervoltage release 208-230V AC.
