The 800 V rated insulation voltage means it handles 480 V and 600 V class systems without derating the insulation gap. An undervoltage release is built in, so you can drop the breaker on loss of control voltage — typical for emergency-stop chains or undervoltage protection schemes. Communication function is onboard, which means it can report status or trip events to a BMS or PLC without an add-on module. ## Interrupting capacity — what the ratings mean At 240 V the breaker clears 187 kA symmetrical — that is well above typical service-entrance fault levels in North American 120/208 V or 277/480 V panels. At 415 V and 440 V it still holds 121 kA, covering most IEC industrial grids. At 500 V it drops to 75.6 kA, and at 690 V to 3 kA — the last is a low range, so if your system runs 690 V with high fault current, this breaker is not the right fit. The 63 A frame stays flat-rated across 40 °C to 70 °C ambient — no derating needed in a warm enclosure. The breaker measures 105 mm wide, 181 mm tall, and 86 mm deep — a standard three-pole MCCB footprint for a 63 A frame. The 86 mm depth (3.39 in) means it fits most 200 mm deep enclosures with room for wiring gutters.","metaTitle":"SENTRON 3VA2063-5KP32-0DA0 MCCB, 63 A, 3-Pole, 187 kA at 240","metaDescription":"SENTRON 3VA2063-5KP32-0DA0 molded case circuit breaker, 63 A continuous, 3-pole line protection, 187 kA interrupting at 240 V.
