Breaking capacity is 242 kA at 240 V AC and 187 kA at 415 V and 440 V, then 121 kA at 500 V, and 4.5 kA at 690 V. The 4.5 kA at 690 V tells you this breaker is at home on 400 V class systems, not 690 V drives. ## Ground-fault monitoring built in This version includes summation-current ground-fault monitoring on the L + N conductors. That means it measures the vector sum of phase and neutral currents — catches ground faults without needing a separate core-balance CT or external relay. It's a line-protection design, not a motor-protection or generator breaker, so the trip curve is shaped for cable and busbar protection. That's a standard SENTRON 3VA frame footprint — fits existing 3VA panel layouts and busbar systems.","metaTitle":"Siemens 3VA2225-6HM42-0AA0 SENTRON MCCB, 250 A, 4-Pole","metaDescription":"Siemens SENTRON 3VA2225-6HM42-0AA0 molded case circuit breaker, 250 A continuous at 40 °C, 4-pole, 242 kA breaking at 240 V.
