This 3VA2463-5JP32-0AA0 is a 3-pole SENTRON molded case circuit breaker rated 630 A continuous at 40 °C, with an ETU550 electronic trip unit and integrated communication. At 415 V and 440 V it still holds 121 kA, dropping to 75.6 kA at 500 V and 9 kA at 690 V, so the voltage class of your distribution drives the SCCR coordination study. The 630 A frame is sized for main feeders or large motor branch circuits; the electronic trip gives adjustable long-time, short-time, instantaneous, and ground-fault curves, which means selectivity with downstream breakers is configurable, not fixed. Thermal derating is published across the operating range: 630 A at 40 °C, 600 A at 45 °C, 570 A at 50 °C, 540 A at 55 °C, 510 A at 60 °C, 480 A at 65 °C, 450 A at 70 °C.
Dimensions: 248 mm height, 138 mm width, 110 mm depth. Communication function is built in — the ETU550 supports Modbus RTU via the optional COM module, so it can report trip events and load data to a BMS or PLC without an external gateway. No undervoltage release or shunt trip is integrated (: No). If you need UVR or shunt-trip control, those are external accessories that mount on the left side of the breaker. The trip indicator is not built into the front face (: No) — tripped status is read from the handle position or via the communication module.
