Breaking capacity is the headline number for an MCCB, and this one delivers 187 kA at 240 V, dropping to 121 kA at both 415 V and 440 V, then 75.6 kA at 500 V, and 3 kA at 690 V. Dimensions are 181 mm tall by 105 mm wide by 86 mm deep — that 105 mm width is three 35 mm DIN-rail modules side by side, so it occupies three full positions on the rail. If you're swapping into an existing panel, check the gland-plate cutout and the bus-bar spacing: the 3-pole footprint is fixed, but the 105 mm width is wider than some compact MCCBs. Power loss is rated at 13.5 W maximum — that's the heat it dumps into the enclosure at full rated current. For a multi-breaker panel, sum those losses to size the ventilation or forced-air cooling. ## Communication and auxiliary switching The breaker includes a communication function, so it can integrate with a building management system or remote monitoring setup — no separate communication module required for basic status. It also ships with a 1 auxiliary switch + 1 trip alarm switch HQ, giving you one set of contacts for breaker position and one for trip indication. That's enough for a remote fault annunciation and a status light on the panel door without adding accessories. The trip indicator is present, so you get a visual flag when the breaker has tripped on fault.","metaTitle":"Siemens 3VA2010-5JQ32-0AF0 SENTRON MCCB, 100 A, 3-Pole","metaDescription":"Siemens SENTRON 3VA2010-5JQ32-0AF0 molded case circuit breaker, 100 A rated, 3-pole, 187 kA at 240 V.
