It is a 3-pole unit rated for 25 A continuous current, with an adjustable thermal-magnetic trip that can be set between 38 A and 300 A — meaning you dial in the overload pickup to match the downstream cable or load, not the other way around. Breaking capacity is the real differentiator here: 440 kA at 240 V AC, 330 kA at 415 V, and still 220 kA at 500 V.
Ratings that matter for the panel builder
Power loss is only 0.5 W, negligible for thermal budgeting.
The 105 mm width matches the typical 3-pole frame spacing, so it drops into a cutout or busbar system designed for that pitch.
Communication and monitoring features
This breaker includes a communication function and supports summation current ground-fault monitoring on the L-conductor. No undervoltage release or voltage-triggered trip is built in.
