Its 187 kA breaking capacity at 240 V AC means it can safely interrupt very high fault currents at typical North American line voltages — a figure that drops to 121 kA at 415 V and 75.6 kA at 440 V, still well above what most distribution panels will ever see. This is a line-protection design, so it is intended for feeder or main breaker duty, not motor branch-circuit protection with an overload relay. The 70 mm depth and 130 mm height keep it within the standard SENTRON 3VA1 panel footprint — it will fit existing 3VA1 mounting bases and busbar connections without re-drilling. The 76.2 mm width is a three-module (3 x 25.4 mm) form factor, so it occupies three positions on the DIN rail or panel-mount plate. ## Shunt trip and release detail The shunt trip (STL) auxiliary release allows remote tripping by applying a control voltage to the release coil — useful for emergency-stop circuits, PLC-driven load shedding, or interlocking with a fire-alarm panel. The TM240 overcurrent release is a thermal-magnetic type with a fixed thermal element and magnetic pickup calibrated for the 63 A frame — no field-adjustable trip unit, which simplifies specification but locks the protection curve. Above that, derating is gradual: 62 A at 55 °C, 61 A at 60 °C, 60 A at 65 °C, and 58 A at 70 °C (–).","metaTitle":"Siemens 3VA1163-5EF36-0HA0 SENTRON MCCB, 63 A, 3-Pole, 187 k","metaDescription":"Siemens SENTRON 3VA1163-5EF36-0HA0 molded case circuit breaker, 63 A rated, 3-pole, 187 kA breaking at 240 V.
