Breaking capacity runs 187 kA at 240 VAC, 121 kA at 415/440 VAC, 75.6 kA at 500 VAC, and 3.7 kA at 690 VAC, which covers most industrial service-entrance and feeder applications. ## Ground-fault and protection design This MCCB includes ground-fault monitoring via summation current formation on the L + N conductors — it measures the vector sum of line and neutral current to detect leakage to ground. The design is line protection, meaning it's set up for feeder and main breaker duty rather than motor or generator protection. Power loss is 10 W maximum, so heat dissipation in a sealed cabinet is manageable. The 4-pole format (3 phases + neutral) is common for North American 120/208 V or 277/480 V wye systems where the neutral needs overcurrent protection.","metaTitle":"Siemens 3VA2110-5HM46-0AA0 SENTRON MCCB, 100 A, 4-Pole, 187","metaDescription":"Siemens SENTRON 3VA2110-5HM46-0AA0 molded case circuit breaker, 100 A continuous, 4-pole, 187 kA breaking capacity at 240 VAC.
