Product details

It delivers 40 kA Icu at 220/240 V AC and 36 kA Icu at 380/400 V AC, conforming to IEC 60947-2 — sufficient for distribution panels where fault current levels stay within those limits. The fixed backplate mount and front-connect terminals simplify panel layout for a 150 mm wide, 257 mm tall footprint.

The F breaking capacity code means 40 kA Icu at 220/240 V AC and 36 kA Icu at 380/400 V AC — the fault current the breaker can safely interrupt without damage. At 440 V AC the rating drops to 30 kA Icu. The TM-D trip unit provides fixed long-time pickup at 1 In (350 A) and a fixed instantaneous trip threshold of 3500 A — 10× In. This suits distribution feeders where the load is predictable and no adjustable trip curve is needed.

IP40 front-face protection keeps dust and tools out of the enclosure; IK07 impact resistance handles incidental knocks during panel assembly. Mechanical durability is rated at 15000 cycles, electrical durability at 12000 cycles at 415 V at In/2 — enough for infrequent switching in distribution duty where the breaker operates only under fault or maintenance isolation.
