Auxiliary contact ratings: 1 A at 24 V, 2 A at 110–125 V, 0.5 A at 230 V, 0.15 A at 60 V. If you're wiring a 24 VDC PLC input to the breaker's status contact, that 1 A rating covers the signal loop with margin.
Dimensions are 90 mm high, 45 mm wide, 75 mm deep. Clearance specs: 20 mm upwards and downwards, 9 mm at the side. That side gap is tight — adjacent breakers or terminals can sit right next to it without an air gap spacer. Terminal capacity: accepts 2 x (0.5 to 1.5 mm²) or 2 x (0.75 to 2.5 mm²) solid or stranded. M3 screws on the main contacts.
Environmental range and handling
Operates from -20 °C to +60 °C; stores and ships from -50 °C to +80 °C. That storage range covers unheated warehouses and truck trailers in winter — the -50 °C floor is for the part in its packaging, not running. Rated switching frequency: 15 operations per hour at AC-3 and AC-3e duty. That's fine for a motor start once every four minutes — not for a rapid-cycling load like a stamping press or reciprocating compressor.
