Line protection breaker with TM210 trip
The Siemens SENTRON 3VM1110-3ED32-0AA0 is a 3-pole molded case circuit breaker designed for line protection. It carries a TM210 thermal-magnetic overcurrent release — the thermal element handles overloads, the magnetic element handles short-circuits. Rated 100 A continuous at 40 °C ambient, it derates predictably to 91 A at 70 °C. Breaking capacity hits 76 kA at 240 VAC, 53 kA at 415 VAC, and 32 kA at 440 VAC — figures that cover most industrial distribution panels. The TM210 designation means the thermal pickup is fixed at 100 A. No undervoltage release, no ground-fault module, no communication. Insulation voltage rated 800 V.
Dimensions and panel fit
At 76.2 mm wide, 130 mm tall, and 70 mm deep, the 3VM1110-3ED32-0AA0 fits the standard SENTRON 3-pole MCCB footprint. Front IP40 protection handles basic panel dust; the breaker is intended for enclosed installation inside a switchboard or distribution box. Power dissipation maxes at 25 W at rated load — account for that heat in the enclosure thermal calculation.
