That's unusual; many breakers start stepping down above 40 °C. Here, per the datasheet, the full 63 A is available all the way to 70 °C ambient. This variant includes summation-current ground-fault monitoring on the L-conductor path — it measures vector sum of phase currents to detect leakage to ground. It's a straightforward line-protection MCCB with integral ground-fault sensing, suited for main or feeder breakers in distribution panels where ground-fault coordination is required. ## Panel integration — dimensions and mounting The 3-pole footprint matches the SENTRON 3VA2 family; if you're replacing an existing 3VA2 breaker, the bus-bar stab pattern and terminal spacing are consistent across the series. Maximum power loss is 4 W at rated current. That's low enough that forced ventilation is unnecessary in most enclosures, but in a densely packed panel with multiple breakers at full load, cumulative heat should still be checked against the enclosure's dissipation rating.","metaTitle":"Siemens 3VA2163-6HM32-0AA0 SENTRON MCCB, 63 A, 3-Pole, 242 k","metaDescription":"Siemens 3VA2163-6HM32-0AA0 SENTRON molded case circuit breaker, 63 A continuous, 3-pole, line protection with ground-fault monitoring. 242 kA interrupting at 240 V.
