It carries a full-scale current of 63 A with an adjustable thermal-magnetic trip that can be set anywhere from 16 A to 63 A — so you dial it to match the load, not the other way around. The trip indicator gives you a clear visual when it's opened on fault, which saves chasing ghosts on a panel. At 240 V it's rated 187 kA, at 415 V and 440 V it holds at 121 kA, at 500 V it's 75.6 kA, and at 690 V it drops to 3.7 kA. No derating needed in a hot panel or near a motor starter — that's a real advantage when you're packing breakers into a crowded enclosure.
A communication function is built in, so this breaker can talk to a higher-level system for monitoring and remote trip — no separate comm module needed for basic integration.
