The Siemens 3VM1110-3ED42-0AA0 is a SENTRON molded case circuit breaker rated for 100 A continuous current at 40 °C, holding that rating flat through 50 °C before a gentle derating curve begins — 98 A at 55 °C, 96 A at 60 °C, down to 91 A at 70 °C. Four poles, TM210 thermal-magnetic trip unit, no ground-fault monitoring, no motor drive option — this is a straight line-protection MCCB for distribution panels where you need a clean 100 A feed with adjustable instantaneous pickup up to 1000 A.
Breaking capacity by system voltage — the real SCCR story
Interrupting capacity varies sharply with system voltage: 76 kA at 240 V AC, 53 kA at 415 V, 32 kA at 440 V, and 12 kA at 500 V. On a 480 V panel you're between the 440 V and 500 V figures — plan conservatively.
Dimensions are 101.6 mm wide by 130 mm tall by 70 mm deep — a standard 4-pole MCCB footprint that drops into SENTRON distribution blocks and panelboards without adapters. Front face carries IP40 protection; the rest of the enclosure is open to the panel interior, so mount where cabinet IP rating handles the environment.
