Its 187 kA interrupting capacity at 240 V and 121 kA at 415 V give it the headroom to clear high-fault conditions without cascading upstream — a key consideration when coordinating selective tripping on a main or feeder breaker. ## Breaking capacity and thermal performance This MCCB delivers 187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 3 kA at 690 V. That voltage-dependent curve is typical of a current-limiting design — the arc extinction method changes effectiveness above 500 V, so the 690 V rating drops sharply. For a 480 V panel (common in North American industrial plants), the 75.6 kA figure is the one to size against the available fault current. The continuous current rating holds at 63 A across the entire ambient temperature range from 40 °C to 70 °C — no derating needed. That simplifies panel layout if the breaker sits near other heat sources inside a sealed enclosure. Power loss is 5.4 W maximum. At 105 mm wide, 181 mm tall, and 86 mm deep, this breaker fits the standard SENTRON 3VA mounting footprint. ## Auxiliary switching and options This variant ships with three auxiliary switches (HQ type) integrated. The base switch assembly part number is 3VA20635HN360AA0.","metaTitle":"Siemens 3VA2063-5HN36-0AD0 SENTRON MCCB, 63 A, 3-Pole, 187 k","metaDescription":"Siemens SENTRON 3VA2063-5HN36-0AD0 molded case circuit breaker, 63 A continuous, 3-pole, line protection.
