Product details

Panel fit and mounting — size S00 on 35 mm DIN rail

The 3RH2431-1UW80: This SIRIUS auxiliary contactor is frame size S00, with a width of 90 mm, depth of 117 mm, and height of 57.5 mm — the footprint fits standard 35 mm DIN rail panels where space is allocated for a contactor of this class. Mounting is via screw or snap-on onto 35 mm DIN rail; the mounting position allows ±180° rotation on a vertical surface and ±22.5° tilt forward/backward, giving flexibility in crowded enclosures. Clearance distances are specified: 10 mm upwards, 10 mm forwards, 10 mm downwards, and 6 mm at the side — these are the minimum air gaps to maintain for arc flash and heat dissipation per the datasheet.

Contact ratings and switching capability

Three instantaneous NO contacts are rated for AC and DC switching: at 24 V rated value the contact carries 10 A, at 230 V rated value also 10 A, and at 400 V rated value 3 A — these are the thermal current limits for the contact set under the stated voltage conditions. DC switching ratings are given per voltage step: 4.7 A at 60 V, 3 A at 110 V, 1.2 A at 220 V, 0.5 A at 440 V, 0.26 A at 600 V — the current drops as voltage rises due to arc extinction limits in DC circuits. Mechanical endurance is 5,000,000 operating cycles typical; the maximum switching frequency at AC is 10,000 operations per hour, which sets the duty cycle for high-speed applications like conveyor or packaging lines.
