It is designed for distribution applications and carries a 25 kA Icu at 380/415 V AC 50/60 Hz per IEC 60947-2, with a higher 40 kA Icu at 220/240 V AC. The breaker is rated for isolation and is suitable for horizontal or vertical mounting on a backplate.
The thermal-magnetic TM-D trip unit provides L (overload) protection via a thermal bimetal and I (short-circuit) protection via a magnetic coil — no electronic adjustments, so it's a fixed-curve device suited for straightforward feeder or branch-circuit protection. The breaker is rated for 50,000 mechanical cycles and 30,000 electrical cycles at 440 V In, which covers frequent switching in panel applications. Power dissipation is 8.77 W per pole — factor this into enclosure thermal calculations to avoid derating in a sealed cabinet. IP40 protection means the breaker is protected against solid objects >1 mm (tools, wires) but not water ingress — suitable for indoor panel installation. IK07 confirms impact resistance to 2 J, enough for accidental tool strikes during commissioning.
Overvoltage category III suits fixed-installation distribution boards. No earth-leakage protection is integrated — external RCD or RCBO needed if ground-fault protection is required.
