That 63 A is the full-scale value; the adjustable thermal trip starts at 16 A minimum, so this breaker covers motor feeders and distribution subfeeds that need a 63 A frame but a lower trip setting. Breaking capacity is 187 kA at 240 V, 121 kA at 415/440 V, and still 75.6 kA at 500 V — that SCCR headroom lets it sit ahead of a transformer or close to a high-fault service entrance without cascading upstream. Three-pole construction, line-protection design (no ground-fault or energy-reducing maintenance switch built in). The auxiliary switch block ships as 2 aux + 1 trip-alarm HQ contacts. Undervoltage release is factory-installed — coil holds at nominal, drops out below threshold, which locks the breaker open until the UVR is manually reset. Bolts into a standard panel-mount cutout. Communication function is onboard.","metaTitle":"Siemens 3VA2063-5JQ32-0DH0 SENTRON MCCB, 63 A, 3-Pole, 187 k","metaDescription":"Siemens SENTRON 3VA2063-5JQ32-0DH0 molded case circuit breaker, 63 A rated, 3-pole, 187 kA at 240 V.
