What this MCCB delivers for your panel
The Siemens 3VA2163-5HL36-0KC0 is a SENTRON molded case circuit breaker rated for continuous 63 A across its full operating temperature range of -25 °C to 70 °C, with no derating needed up to 70 °C. Its interrupting capacity reaches 187 kA at 240 V and 121 kA at 415 V, giving you headroom for high-fault installations like transformer secondaries or large motor control centers. The 3-pole design includes a factory-fitted shunt trip (STL) and two auxiliary switches (HQ), so it arrives ready for remote tripping and status feedback without extra wiring.
Breaking capacity across voltage levels
This MCCB delivers 187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 3.7 kA at 690 V. The steep drop at 690 V is typical for a 63 A frame; if your fault current at 690 V exceeds 3.7 kA, you need a higher-rated frame or a current-limiting upstream device. At 415 V the 121 kA rating covers most industrial service entrances and large sub-distribution boards.
Panel fit and dimensions
The breaker measures 105 mm wide, 181 mm high, and 86 mm deep. It mounts on a standard DIN rail or can be screw-fixed to a backplate. The 86 mm depth leaves clearance for rear-connected busbars or cable ducts in a 200 mm deep enclosure. The 3-pole footprint matches the SENTRON 3VA2 family, so a panel laid out for a 3VA2116 frame will accept this unit with no drilling changes.
