63 A MCCB with 242 kA interrupting capacity
The Siemens SENTRON 3VA2163-6HN32-0HL0 is a 3-pole molded case circuit breaker rated for 63 A continuous current across the full ambient range from 40 °C to 70 °C — no derating needed up to that ceiling. Its interrupting capacity hits 242 kA at 240 V, 187 kA at 415 V and 440 V, 121 kA at 500 V, and 3.7 kA at 690 V, so it handles high-fault scenarios common in industrial distribution without cascading upstream breakers. Designed for line protection, this MCCB carries a shunt trip release (STL) plus two auxiliary switches, one trip alarm switch, and one electrical alarm switch — enough status feedback for a PLC or remote monitoring system without an add-on module.
The 3-pole footprint matches the SENTRON 3VA2 family, so if you're swapping into an existing panel, check the busbar spacing — same pole pitch as the rest of the series. No undervoltage release on this variant, so if your safety circuit requires UVR, you'll need to add it externally or spec a different suffix.
Auxiliary and trip configuration
That's a full complement of status contacts for most control schemes without needing a separate accessory kit. The trip indicator and voltage trigger are built in, so you get local visual indication and remote signal capability. Communication function is not included on this variant — no integrated Modbus or PROFIBUS; if you need that, look at the 3VA2 with communication option.
Environmental and storage specs
That covers most indoor panel environments, including unheated warehouses in cold climates.
