It carries a rated insulation voltage of 800 V and delivers interrupting capacity of 242 kA at 240 V, 187 kA at 415 V, and 4 kA at 690 V — meaning it can clear fault currents up to those levels without cascading upstream, a key selectivity number for panel coordination.
Rated current and thermal derating — the real selection number
At 55 °C it drops to 96.25 A, at 60 °C to 92.5 A, at 65 °C to 88.75 A, and at 70 °C to 85 A. The maximum power loss is 13.5 W — negligible for most enclosures but worth checking if you're packing breakers tight.
Trip unit and auxiliary contacts
The breaker ships with 2 auxiliary switches (HP type) pre-installed, so you get status feedback without adding a separate accessory. It does not include undervoltage release, communication module, or ground-fault monitoring — those are separate options if your spec requires them.
