63 A MCCB with 242 kA interrupting capacity — line protection for high-fault panels
The SENTRON 3VA2063-6HN32-0CC0 is a 3-pole molded case circuit breaker rated for 63 A continuous current across the full ambient range up to 70 °C, with a maximum breaking capacity of 242 kA at 240 V AC. That interrupting rating drops to 187 kA at 415 V and 440 V, 121 kA at 500 V, and 3 kA at 690 V — so the 240 V figure is the headline, but the 415 V number is the one that governs in most industrial distribution panels. Designed for line protection (not motor or generator protection), it ships with an undervoltage release and two HQ auxiliary switches integrated. Power loss is 7.9 W maximum, which keeps heat manageable in a tightly packed enclosure. Operating temperature range is -25 °C to 70 °C; storage range is -40 °C to 80 °C. The 86 mm depth, 105 mm width, and 181 mm height fit standard MCCB panel cutouts — no special adapter plate needed for most 3-pole 63 A footprints.
Built-in undervoltage release and auxiliary switches — no add-on module needed
The 3VA2063-6HN32-0CC0 includes an undervoltage release (UVR) as standard and two HQ auxiliary switches. That means the UVR coil wiring is part of the base unit — no separate shunt trip or UVR accessory to order and install. The auxiliary switches provide status feedback for the open/closed position without an extra side-mount block. Communication function is not present, so this is a straight hardwired breaker for conventional distribution panels.
