Motor protection and trip behaviour
At 400 V the breaker is rated for a 1.5 kW motor; the same unit covers smaller loads down to the minimum setting of the adjustable thermal element.
Screw-type terminals on the main circuit accept 2x (0.5…1.5 mm²) solid or 2x (1…2.5 mm²) stranded — common for panel wiring with ferrule or direct termination. Auxiliary contacts are transverse design; the breaker ships with an auxiliary switch block fitted (0 built-in auxiliary contacts on the base unit, so the switch is an add-on module).
Environmental limits and mounting
Rated for -20 to +60 °C operating ambient, storage down to -50 °C, with shock resistance of 25 g / 11 ms — suitable for machine-mounted panels on presses or conveyors. Mountable in any position, with zero clearance required at the sides or rear — no derating needed for tight panel layouts.
