It's the motor protection variant, meaning the ETU350M electronic release includes phase failure detection and undervoltage release, so it's built for motor branch circuits where you need coordinated protection against single-phasing and brownout conditions. The interrupting ratings on this breaker are the real story. At 240 V it clears 187 kA — that's utility-grade fault current, typical for large transformer secondaries or industrial service entrances. At 415 V and 440 V it holds 121 kA, and at 500 V it still manages 75.6 kA. The drop to 3.7 kA at 690 V tells you this is a 600 V class frame; don't spec it for 690 V motor circuits unless the available fault current is well under that.","metaTitle":"Siemens 3VA2110-5MN32-0BA0 SENTRON MCCB, 100 A, 187 kA at 24","metaDescription":"Siemens SENTRON 3VA2110-5MN32-0BA0 molded case circuit breaker, 100 A, 3-pole, motor protection with ETU350M release. 187 kA at 240 V, 121 kA at 415 V.
