The Siemens SENTRON 3VA1110-6GF46-0AA0 is a 4-pole molded case circuit breaker (MCCB) rated for line protection, carrying a continuous current of 100 A up to 50 °C before derating begins — at 55 °C it holds 98 A, at 60 °C it holds 96 A, and at 70 °C it still delivers 91 A, so the thermal headroom is generous for a warm panel. The TM240 overcurrent release is adjustable, letting you tune the thermal trip band to the load without swapping the breaker body. Breaking capacity is the headline here: 220 kA at 240 V, 154 kA at 415 V, and 121 kA at 440 V — that puts it squarely in the high-interrupting class for large transformer secondaries or bus-tie applications where fault current runs high. At 500 V and 690 V the rating drops to 17 kA, so for 480 V or 600 V class systems the available fault current needs checking against that ceiling.
Sizing and coordination
Integration
Dimensions are 70 mm deep, 101.6 mm wide, and 130 mm tall — the 4-pole width (about 4 inches) is the critical dimension for DIN-rail or mounting-plate layout in a retrofit panel.
