Its interrupting capacity hits 75.6 kA at 240 V and 52.5 kA at 415 V — enough headroom for most industrial distribution panels where fault currents run high. ## Ratings that matter for your BOM line At 55 °C it still carries 60.48 A, and at 70 °C it delivers 56.7 A — useful when the breaker sits in a warm enclosure near other heat sources. The interrupting ratings span multiple voltage levels: 75.6 kA at 240 V, 52.5 kA at 415 V, 32 kA at 440 V, and 10.5 kA at 690 V. That 690 V number is the one to check if your line runs at 600 V or 690 V class; it still clears 10.5 kA, which covers most secondary distribution faults. ## What's built in and what's left out The breaker ships with 2 auxiliary switches HP (high-performance) integrated, so you get remote status indication without adding a separate accessory module. The TM240 release is fixed, not adjustable for long-time pickup, but the adjustable response time tr max is 1 second.","metaTitle":"Siemens SENTRON 3VA1163-3EF36-0AB0 MCCB, 63 A, 3-Pole, 75.6","metaDescription":"Siemens SENTRON 3VA1163-3EF36-0AB0 molded case circuit breaker, 63 A rated, 3-pole, 75.6 kA at 240 V.
