It's a 3-pole, 63 A frame with a compact footprint: 181 mm high, 105 mm wide, 86 mm deep, which fits standard panel layouts without forcing a wider enclosure. The interrupting ratings are serious — 330 kA at 240 V, 242 kA at 415 V, and still 187 kA at 500 V — so it can handle high-fault installations like transformer secondaries or large motor centers where upstream fault current is substantial. At 690 V it drops to 3.7 kA, which is typical for a 3-pole MCCB on a 690 V line; that's still adequate for most 690 V motor circuits but worth noting if you're close to the transformer.
Rated current and thermal performance — no derating up to 70 °C
That's unusual — most MCCBs start derating above 40 °C, but this one doesn't, so you can install it in a warm cabinet or near a motor without losing capacity. The maximum power loss is 4 W, which is low for a 63 A frame, so heat buildup in a dense panel is manageable.
Integration notes: auxiliary switches and trip alarm
That means you get remote status indication (open/closed) plus a separate signal for a trip event, without needing to add a separate auxiliary release. The basic switch supplied is 3VA2163-7MS32-0AA0, which is the same frame with a different accessory set. Panel cutout dimensions match the standard 3VA 3-pole footprint, so a panel designed for a 3VA2163-8HM32-0AA0 will accept this one without rewiring — same mounting hole pattern, same bus-bar spacing.
