The 17 kA at 690 V still covers most 690 V motor circuits in mining or marine installations. ## Thermal derating — real-world current capacity in a warm panel At 55 °C it derates to 60.48 A, at 60 °C to 59.22 A, at 65 °C to 57.96 A, and at 70 °C to 56.7 A. That derating curve matters when the breaker is enclosed in a non-ventilated panel alongside other heat-generating devices — a common scenario in motor control centers. If the panel ambient runs at 60 °C, the breaker's effective continuous current is 59.22 A, not 63 A. ## Integration notes — what fits in the panel The breaker measures 105 mm wide, 181 mm tall, and 86 mm deep — a standard 3-pole MCCB footprint that fits Siemens 3VA2 panelboards and most DIN-rail or mounting-plate layouts. The shunt trip (STL) is wired separately from the main power path; it requires a control voltage to trip the breaker on command, typically from an emergency-stop circuit or a remote undervoltage relay. The two auxiliary switches (HQ) provide one N/O and one N/C contact each, rated for the control circuit voltage.","metaTitle":"Siemens 3VA2163-5MN36-0KC0 SENTRON MCCB, 63 A, 187 kA at 240","metaDescription":"Siemens 3VA2163-5MN36-0KC0 SENTRON molded case circuit breaker, 63 A rated, 187 kA breaking at 240 V.
