That rating means it clears high-fault currents on the main distribution board without cascading upstream, so you can hold selectivity on a 415 V bus with a transformer-fed switchboard. The ETU850 electronic trip unit gives you LSI protection: long-time (Ir) adjustable 250 A to 630 A, short-time (Isd) 0.6 to 9× In, and instantaneous (Ii) 1.5 to 9× In. Neutral protection is adjustable from OFF up to 100% of the phase setting — useful on a 4-wire system where you need to coordinate the neutral with the phase conductors. The UVR drops the breaker on loss of control voltage — standard for emergency-stop chains or undervoltage protection schemes. The 3VA2 platform is Siemens' main IEC MCCB family for commercial and industrial distribution. For a 480 V system, check the derated Icu; the IEC frame 630 is typically rated at 480 V as well, but the exact figure depends on the specific UL or IEC listing. The adjustable LSI curve and neutral protection make this breaker suitable for main or tie applications on a 4-wire, 3-phase distribution panel where you need to protect the neutral conductor against overload from harmonic currents. The UVR at 24 V DC integrates with a safety PLC or emergency-stop relay that drops the main breaker on a trip condition.","metaTitle":"Siemens 3VA2463-6KP42-0BC0 Circuit Breaker, 630A, 85kA @ 415","metaDescription":"Siemens 3VA2463-6KP42-0BC0 IEC frame 630 circuit breaker, breaking capacity class H, Icu=85kA @ 415V, 4-pole, ETU850 LSI protection, 630A.
