The adjustable thermal-magnetic trip range spans 95 A to 756 A, giving the specifying engineer flexibility to match the breaker to downstream load without swapping frames. At 240 V the interrupting rating climbs to 187 kA; at 500 V it still holds 75.6 kA. Only at 690 V does it drop to 3 kA — a reminder that this frame is optimized for 400–500 V class systems, not 690 V industrial grids.
The internal basic switch is pre-configured as 3VA20635KP320AA0, and the auxiliary switch bay carries two HQ-style aux switches, simplifying integration into a control circuit that needs breaker status feedback.
Power dissipation is 5.4 W maximum — low enough that thermal derating in a sealed enclosure is minimal, but worth checking against the panel's total heat budget if multiple breakers are ganged.
