SENTRON 3VM1110-3EE42-0AA0 — 100 A MCCB with TM220 release
The Siemens SENTRON 3VM1110-3EE42-0AA0 is a 4-pole molded case circuit breaker (MCCB) rated for line protection, carrying a TM220 thermal-magnetic overcurrent release. Its continuous current rating holds at 100 A from 40 °C through 50 °C, then derates to 98 A at 55 °C, 96 A at 60 °C, 94 A at 65 °C, and 91 A at 70 °C — a derating curve that matters when the breaker shares a crowded enclosure with other heat sources. Breaking capacity is 76 kA at 240 V, 53 kA at 415 V, 32 kA at 440 V, and 12 kA at 500 V; the 415 V figure is the one that governs most European 400 V distribution panels, and the 240 V figure covers North American 240/120 V split-phase service.
Dimensions and panel fit
The breaker measures 101.6 mm wide, 130 mm high, and 70 mm deep. That 70 mm depth is the dimension that determines gland-plate clearance and whether the breaker fits a shallow wall-mount enclosure without a deep extension box. Width at 101.6 mm is a standard 4-inch footprint for a 4-pole MCCB; verify the busbar or lug kit pitch matches the existing panel layout if retrofitting.
