Motor protection breaker built for the grit and heat
Operating temperature spans -20 to +60 °C, so it survives a hot control room next to a kiln or a compressor shed in summer. Screw terminals on both the main and auxiliary circuits accept solid conductors from 0.5 to 1.5 mm² and stranded up to 6 mm², which covers most motor feeder wiring. At 45 mm wide and 97 mm tall, it occupies a single modular space on the rail — plan your fill factor accordingly.
Auxiliary switch and wiring notes
The breaker supports an auxiliary switch with a transverse design, which means the contacts open sideways — useful for signaling the PLC or safety relay that the breaker has tripped. The auxiliary contacts are rated 1 A at 24 V, 0.5 A at 230 V, and 0.15 A at 60 V. That 24 V rating covers most PLC input cards; the 230 V rating handles control transformers. Keep the switching frequency at AC-3 duty to a maximum of 15 operations per hour — this is a protection device, not a cycled contactor.
