This breaker mounts to a backplate — no DIN-rail clip, so plan for screw-down or busbar mounting. The 81 mm width and 137 mm height fit standard distribution panel layouts. Connections are front-facing, accepting compression lugs or busbars with a 35 mm pitch (27 mm without spreaders).
Electrical durability is rated at 20,000 cycles at 440 V at rated current, with 10,000 cycles at 440 V at In.
It carries a 36 kA interrupting capacity at 415 V AC (performance level F), which means it can handle high fault currents typical in industrial distribution panels.
It is certified to EN/IEC 60947-2 and is suitable for isolation as defined by that standard.
This part is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time.
