The Siemens SENTRON 3VA1110-5ED42-0AA0 is a 4-pole molded case circuit breaker (MCCB) with a TM210 thermal-magnetic trip unit, designed for line protection in distribution panels. Rated 100 A continuous at 40 °C, it maintains that rating through 50 °C and derates to 91 A at 70 °C — useful data for a panel builder calculating fill factor and heat rise in an enclosed switchboard.
Breaking capacity is specified across five voltage levels: 187 kA at 240 V, 121 kA at 415 V, 75.6 kA at 440 V, and 17 kA at both 500 V and 690 V. That spread tells a site electrical engineer where this breaker can be applied without cascading upstream — the 187 kA figure at 240 V covers most North American 277/480 V panel main applications, while the 17 kA at 690 V suits European 400 V industrial networks with high fault current.
Dimensions are 101.6 mm wide, 130 mm tall, and 70 mm deep. The IP40 protection class on the front means it is splash-protected against solid objects larger than 1 mm but not sealed against water ingress — suitable for indoor panel mounting, not for washdown environments. Rated insulation voltage is 800 V, and maximum power loss is 25 W, which should be factored into the enclosure thermal budget for a multi-breaker lineup.
