That suits a dedicated feeder or a fixed-load branch where you don't need a variable trip setting. The magnetic pickup is factory-set for the high interrupting rating. At 55 °C the breaker carries 60.48 A, at 60 °C it's 59.22 A, and it drops to 56.7 A by 70 °C. That's a compact footprint for a 63 A MCCB with this interrupting rating. No undervoltage release, no shunt trip, no ground-fault module on this variant. It carries a mechanical endurance of 15,000 operations, which is typical for a distribution-grade MCCB — not a switching-duty contactor, but fine for infrequent manual or remote operation.","metaTitle":"Siemens 3VA1163-5EF32-0AH0 SENTRON MCCB, 63 A, 187 kA","metaDescription":"Siemens 3VA1163-5EF32-0AH0 SENTRON 3-pole molded case circuit breaker, 63 A rated current, 187 kA breaking capacity at 240 V, TM240 release.
