80 A thermal-magnetic breaker for distribution panels
The breaking capacity reaches 25 kA Icu at 380/415 V AC, 20 kA at 440 V, and 15 kA at 500 V — enough headroom for most commercial and light industrial panelboards.
The 80 A frame is sized for feeder or large branch circuits; the TM-D trip curve gives a fixed magnetic pickup that coordinates with downstream MCBs. Pollution degree 3 (IEC 60664-1) means it tolerates conductive dust in unsealed enclosures — typical for IP40-rated distribution boards. The 50,000-cycle mechanical endurance and 30,000-cycle electrical endurance at 440 V In suit it for frequent switching in machine-tool or HVAC control panels.
IP40 front face and IK07 impact resistance suit it for enclosed panel installations where occasional tool contact is expected.
