Breaking capacity is 121 kA at 240 VAC, 75.6 kA at 415 VAC, 52.5 kA at 440 VAC, 17 kA at 500 VAC, and 11.9 kA at 690 VAC. That means at a typical 400 V industrial service, you have over 75 kA of interrupting capability — enough for most high-fault locations like substation feeders or large motor starters. The shunt trip allows remote tripping via a control signal, useful for emergency-stop circuits or undervoltage protection schemes. No communication function is built in, so remote monitoring requires the auxiliary contacts wired to an I/O module.","metaTitle":"Siemens 3VA1220-4EF32-0JH0 SENTRON MCCB, 200 A, 3-Pole, 121","metaDescription":"Siemens SENTRON 3VA1220-4EF32-0JH0 molded case circuit breaker, 200 A, 3-pole, 121 kA breaking capacity at 240 VAC.
