The thermal adjustment range of 11.2…16 A lets you fine-tune the overload pickup to match the downstream cable or load — useful when the circuit is lightly loaded and you want to avoid nuisance tripping. That is a practical advantage for service continuity in panelboard applications (250 A or 400/630 A panelboards per the listing). Rated insulation voltage 800 V and impulse withstand 8 kV give headroom for systems where the operational voltage is 415 V but transient overvoltages can spike higher — common in industrial distribution with motor starts or capacitor switching nearby.
Standards & approvals
Certified to BS EN 60947-2, the standard for low-voltage switchgear and controlgear — specifically for circuit breakers. The suitability-for-isolation marking (conforming to the same standard) means it can be used as a visible-break disconnect where local codes require it.
Panel-mounted via backplate, accepting horizontal or vertical orientation — flexibility for tight enclosures. Occupies 4 modules of 35 mm width per pole, so the 4-pole unit takes 140 mm of DIN-adjacent space on the backplate. Toggle control, no earth-leakage module.
