The interrupting rating drops to 75.6 kA at 415 V and 52.5 kA at 440 V, so verify the fault current at your service voltage before specifying. ## Current derating and thermal limits Above that it derates gradually: 62 A at 55 °C, 61 A at 60 °C, 60 A at 65 °C, and 58 A at the maximum operating temperature of 70 °C. The maximum power loss is 17.3 W, which contributes to internal cabinet heating. ## Built-in accessories: shunt trip and auxiliary switches The shunt trip allows remote tripping from a safety circuit or emergency-stop button — a common requirement for automated lines. Two auxiliary contacts give status feedback (open/closed) to a PLC or indication lamp without add-on modules. No undervoltage release is fitted on this unit, so if you need undervoltage protection (UV release) for motor starter coordination, select a different option code. ## Integration and physical fit Dimensions are 130 mm tall, 76.2 mm wide, and 70 mm deep — a standard 3-pole MCCB footprint that mounts on a DIN rail or directly to a backplate via screw terminals.","metaTitle":"Siemens SENTRON 3VA1163-4EF36-0HC0 MCCB, 63A, 121kA at 240V","metaDescription":"Siemens SENTRON 3VA1163-4EF36-0HC0 molded case circuit breaker, 3-pole, 63A rated at 40°C, 121kA breaking capacity at 240V.
