Breaking capacity is voltage-dependent: 187 kA at 240 V, 121 kA at 415/440 V, 75.6 kA at 500 V, and 3 kA at 690 V (–). At 415 V, that 121 kA SCCR gives substantial headroom for high-fault industrial distribution — useful where transformer sizes push available fault current above 100 kA. ## Auxiliary wiring and release complement Factory-fitted with two auxiliary switches, one trip alarm switch, and one electrical alarm switch — covers remote status indication without ordering separate modules. Trip indicator gives a local visual flag when the breaker trips on fault, speeding fault-finding during commissioning or line-down events.","metaTitle":"Siemens 3VA2063-5HL32-0BL0 SENTRON MCCB, 63 A, 3-Pole, 187 k","metaDescription":"Siemens SENTRON 3VA2063-5HL32-0BL0 molded case circuit breaker, 63 A rated, 3-pole, 187 kA breaking at 240 V.
