It delivers 25 kA Icu at 415 V AC (50/60 Hz) per EN/IEC 60947-2, with a higher 40 kA at 240 V and 20 kA at 440 V.
The 80 A TM-D trip provides L (thermal overload) and I (magnetic short-circuit) protection in one block. The thermal element tracks heating in the conductor; the magnetic element clears fast on high faults. At 80 A continuous, this breaker suits feeder circuits or large branch loads — think panelboard mains or subfeeders. The 50,000-cycle electrical endurance at 440 V In/2 and 30,000 at full rated current gives a solid service life for normal switching duty.
Mounts flat on a backplate in horizontal or vertical orientation. Front connections top and bottom — standard for panelboard bus or cable entry. The 35 mm connection pitch matches common busbar spacing.
Current production item in the ComPacT NSX family.
