At 240 V it clears 187 kA — that's a very high fault-current capability for a 63 A frame, typical for a main or large feeder breaker. At 690 V it's 3 kA, which is essentially a low-fault backup rating; you wouldn't spec this for a 690 V main unless the available fault current is known to be under 3 kA. ## Thermal derating — or lack of it That's unusual — most MCCBs start derating above 40 °C. The ETU550 electronic trip compensates electronically, so you don't lose capacity in a warm enclosure. If your panel runs hot, this breaker keeps its full 63 A rating. The IP40 front protection means it's fine for a closed panel; no special sealing needed for the operator interface.","metaTitle":"Siemens 3VA2063-5JP32-0AA0 SENTRON MCCB, 63 A, 3-Pole, ETU55","metaDescription":"Siemens SENTRON 3VA2063-5JP32-0AA0 molded case circuit breaker, 63 A continuous, 3-pole, ETU550 trip unit, 187 kA at 240 V.
