Breaking capacity hits Icu = 55 kA at 415 V — enough headroom for most industrial distribution panels feeding motor control centers. Below that, the breaker still coordinates selectively with downstream devices. The ETU350M is a microprocessor-based trip unit with LSI curves: Long-time (overload), Short-time (short-circuit with delay), and Instantaneous. The adjustable Ir from 250 A to 630 A lets you match the motor full-load current exactly, while Isd and Ii settings provide coordination with downstream contactors and starters. The UVR at 24 V DC means the breaker drops out on control-power loss — verify polarity on the UVR coil before wiring. ## Panel integration The nut keeper kit simplifies terminal tightening on the load side — no loose hardware to drop into live gear. The UVR terminals are clearly marked; keep the control wiring separate from the power conductors to avoid induced noise on the 24 V DC line.","metaTitle":"Siemens 3VA2563-5MN32-0BA0 630A Motor Protection CB, 55kA @","metaDescription":"Siemens 3VA2563-5MN32-0BA0 circuit breaker, 3VA2 IEC frame 1000, 3-pole, 630A, motor protection ETU350M LSI, Icu=55kA @ 415V.
