Its interrupting capacity hits 187 kA at 240 V, 121 kA at 415 V, and 75.6 kA at 500 V, which covers most industrial distribution transformers and motor control center fault levels. This is a line-protection design (not feeder or motor-protection), meaning it's intended for the main incoming or downstream distribution breaker position where selectivity with branch breakers matters. The built-in shunt trip (STL) release lets a remote signal or safety relay trip the breaker independently of the overcurrent mechanism — useful for emergency-off circuits or supervisory shutdown. ## Auxiliary switch complement and wiring note That gives you two form-C contacts for status feedback (open/closed), one contact that changes state only on a trip event (not manual switching), and one contact for remote electrical alarm indication. The auxiliary switches share the same mechanism as the basic switch assembly 3VA20635HN360AA0, so replacement or reconfiguration follows that subassembly part number. The 86 mm depth (3.39 in) and 105 mm width (4.13 in) fit standard SENTRON 3VA panel footprints; verify the 181 mm height (7.13 in) against your enclosure gland plate clearance.","metaTitle":"Siemens 3VA2063-5HN36-0JL0 SENTRON MCCB, 63 A, 3-Pole, 187 k","metaDescription":"Siemens SENTRON 3VA2063-5HN36-0JL0 molded case circuit breaker, 63 A continuous, 3-pole, 187 kA interrupting at 240 V.
