That SCCR figure drops to 121 kA at 415 V and 440 V, then to 75.6 kA at 500 V, and 17 kA at 690 V — so the 240 V rating is the headline number for high-fault installations, but at 400 V class you still have 121 kA, which covers most industrial service-entrance and distribution applications. The 15 000 mechanical endurance cycles (latching) is typical for a frame this size; not a high-cycle application breaker, but fine for main or feeder duty where switching is infrequent. It mounts on a mounting plate or back panel — not DIN rail at this frame size. The shunt trip (STL) is factory-installed (design of the auxiliary release: shunt trip), and the two HQ auxiliary switches are integrated. The basic switch assembly carries order code 3VA2463-5KP32-0AA0, and the integrated auxiliary trip module is 3VA9688-0BL32 — useful if you need to order replacement sub-assemblies. The communication function is onboard, so you can integrate it with a BMS or SCADA system for remote monitoring and trip indication.","metaTitle":"Siemens 3VA2463-5KP32-0JC0 SENTRON MCCB, 630 A, 187 kA at 24","metaDescription":"Siemens 3VA2463-5KP32-0JC0 SENTRON molded case circuit breaker, 630 A rated continuous current, 187 kA breaking at 240 V.
