The unit includes summation-current ground-fault monitoring on L+N, useful for detecting leakage on solidly-grounded systems without a separate GFCI module.","metaTitle":"Siemens 3VA2063-7HM46-0AA0 SENTRON MCCB, 63 A, 4-Pole, 330 k","metaDescription":"Siemens SENTRON 3VA2063-7HM46-0AA0 molded case circuit breaker, 63 A rated, 4-pole, 330 kA breaking capacity at 240 VAC.
