The 45 mm width and 96 mm depth fit standard S00 panel layouts. Screw-type terminals on both main and auxiliary circuits accept 2x (0.5 to 1.5 mm²) solid or stranded, or 2x (0.75 to 2.5 mm²). AWG equivalents: 2x (18 to 12) for main contacts, 2x (20 to 16) for auxiliary. Torque to 0.8 to 1.2 N·m.
Rating context and so-what
Rated 2.5 A at AC-3 for switching motor loads — that is the current the breaker will carry continuously and trip on overload, not the short-circuit rating. Maximum switching frequency at AC-3 is 15 operations per hour. Thermal overload release protects against sustained overcurrent; magnetic short-circuit trip handles fault clearing. Surge voltage resistance rated at 6 kV, shock tested to 25 g / 11 ms per IEC 60068-2-27. Ambient operating range -20 to +60 °C, storage -50 to +80 °C, with 10 to 95 % relative humidity.
