Breaking capacity runs 187 kA at 240 V, 121 kA at 415 V, and 55 kA at 440 V, which gives selectivity headroom for most distribution and motor feeder applications. The ETU860 release offers adjustable long-time (tr 0.5–12 s) and short-time (tsd up to 0.5 s) response values, letting you coordinate with downstream devices without sacrificing fault clearance speed. Maximum power loss is 162 W at rated current. That's the heat the breaker dumps into the enclosure — for a 630 A device, it's moderate but not trivial. ## Mechanical endurance and storage Rated for 15,000 mechanical operations — that's a standard endurance for a frame this size, fine for infrequent switching (fault isolation, maintenance disconnects). Not intended for daily load-break duty; use a contactor for that. ## Communication and monitoring The breaker includes a communication function and other measurement functions — the ETU860 supports optional modules for remote monitoring and trip data. No N-conductor protection on this variant; it's a 3-pole, 3-wire device for delta or solidly-grounded wye systems where neutral protection isn't required.","metaTitle":"Siemens 3VA2463-5KQ32-0KL0 SENTRON MCCB, 630 A, 187 kA","metaDescription":"Siemens SENTRON 3VA2463-5KQ32-0KL0 molded case circuit breaker, 630 A rated at 40 °C, 3-pole, ETU860 electronic trip, 187 kA breaking at 240 V.
