The Siemens SENTRON 3VA1110-5EE32-0CA0 is a 3-pole molded case circuit breaker (MCCB) rated for 100 A continuous current at 40 °C, with a TM220 thermal-magnetic release — meaning it uses a bimetal element for overload protection and a magnetic coil for short-circuit protection, no electronic adjustment. It is a line-protection version, so it is sized for feeder and distribution circuits, not motor-starting duty. There is no auxiliary contact block fitted as standard, no ground-fault monitoring, and no communication module.
Above that, it drops to 96 A at 55 °C, 94 A at 60 °C, 92 A at 65 °C, and 90 A at 70 °C. The breaker body measures 130 mm high, 76.2 mm wide, and 70 mm deep — that 76.2 mm width is a standard 3-pole MCCB footprint for DIN-rail or screw-mount panels, so it drops into the same cutout as other SENTRON 3VA frames.
