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. Power loss is 7.9 W maximum, which keeps heat manageable in a tightly packed enclosure. 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
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.
