The Siemens 3VA2063-5HL32-0KA0 is a SENTRON molded case circuit breaker (MCCB) rated for 63 A continuous current across a -25 °C to 70 °C operating range — no derating needed up to 70 °C. It carries a 187 kA interrupting capacity at 240 V, dropping to 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 3 kA at 690 V. That 187 kA figure at 240 V means it can handle high-fault utility feeds or transformer secondaries without cascading upstream. The 3-pole design is configured for line protection, with a built-in shunt trip (STL) for remote tripping.
Mounting and integration
The MCCB measures 105 mm wide, 181 mm high, and 86 mm deep — a standard SENTRON 3VA footprint that fits existing panel cutouts and DIN-rail adapters. The shunt trip allows remote tripping from a PLC or emergency-stop circuit; wire the STL coil per the terminal diagram on the side label.
