That thermal curve matters when you're packing breakers into a warm enclosure: you lose only about 15 % of the rating at the top of the operating band. That means you can coordinate selectivity downstream without swapping hardware — set the I²t on/off and the short-time pickup to match your feeder breaker. ## Breaking capacity — where it interrupts and where it doesn't Rated short-circuit breaking capacity (Icu) runs 187 kA at 240 V, 121 kA at 415/440 V, 79 kA at 500 V, and 4.25 kA at 690 V. The steep drop at 690 V tells you this breaker is sized for 400–500 V distribution — at 690 V it still clears a fault, but the 4.25 kA limit means you need a higher-rated frame if your available fault current exceeds that. ## Auxiliaries and releases — what's inside the accessory slot The integrated undervoltage release is order code 3VA9608-0BB11; the basic switch module is 3VA2163-5HN36-0AA0. Both are replaceable in the field if the coil or contacts fail, though the UVR coil rating needs to match your control supply. Depth of 86 mm leaves room behind a 200 mm deep enclosure for wiring and the UVR coil.","metaTitle":"Siemens SENTRON 3VA2163-5HN36-0BL0 MCCB, 63 A, 3-Pole, Line","metaDescription":"Siemens SENTRON 3VA2163-5HN36-0BL0 molded case circuit breaker, 63 A rated continuous current, 3-pole, line protection, ETU350 release, 187 kA at 240 V.
