That thermal curve matters if you're packing this into a hot Gulf Coast switchroom or a non-conditioned enclosure. Breaking capacity is the headline here: 187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 52.5 kA at 690 V. That means you get remote trip capability and status feedback without adding external relays. Power loss runs 330 W max at rated load — plan your enclosure ventilation accordingly. Dimensions are 320 mm high by 210 mm wide by 120 mm deep — that's a 12.6 by 8.27 by 4.72 inch footprint. It's a panel-mount MCCB, not a DIN-rail snap-on, so you're bolting it to a mounting plate. The 210 mm width means it'll occupy three standard 70 mm pole spaces on a busbar system. No communication function onboard (no Modbus, no PROFINET), so if you need remote metering or trip data, you're adding an external power meter or a separate communication module upstream. That's standard for indoor industrial gear — fine for most panel environments, but if you're mounting it in a direct-sun roof-top enclosure in Texas, watch the internal ambient. The breaker has a trip indicator and a voltage trigger, so you get local visual confirmation of a trip event without opening the cover.","metaTitle":"Siemens 3VA1510-5EF32-0HH0 SENTRON MCCB, 1000 A, 3-Pole, 187","metaDescription":"Siemens SENTRON 3VA1510-5EF32-0HH0 molded case circuit breaker, 1000 A rated at 40 °C, 3-pole, 187 kA breaking capacity at 240 V.
