Its interrupting capacity is 187 kA at 240 V, 121 kA at 415/440 V, 75.6 kA at 500 V, and 3 kA at 690 V. At 415 V the 121 kA still covers most industrial distribution panels. This variant is designed for line protection (cable/feeder protection), not motor protection — so it's the right choice for a main or distribution breaker in a panel feeding downstream branch circuits. ## Auxiliary switching and trip indication The trip indicator is mechanical — visible on the front of the breaker even without power. The 86 mm depth means it fits in shallow enclosures where a deeper MCCB would hit the door or gland plate. Power loss is rated at 7.9 W maximum — low enough that you don't need forced ventilation in most panels, but worth checking if you're packing multiple breakers in a small enclosure at elevated ambient. The base switch variant is 3VA20635HN320AA0 — the -0BH0 suffix adds the specific auxiliary switch and undervoltage release configuration. Mounting footprint and bus-bar spacing are consistent across the 3VA2 series.","metaTitle":"Siemens 3VA2063-5HN32-0BH0 SENTRON MCCB, 63 A, 3-Pole, 187 k","metaDescription":"Siemens SENTRON 3VA2063-5HN32-0BH0 molded case circuit breaker, 63 A continuous, 3-pole, 187 kA interrupting at 240 V.
