Auxiliary contactor for control-circuit switching
It carries a 10 A rated value at 24 V, with the contact reliability spec of one incorrect switching operation per 100 million cycles at 17 V, 1 mA — meaning it's built for high-integrity signal paths, not just power switching. The coil draws 11 W on closing and holds at 4 W, so the thermal load on the control transformer is modest.
At 45 mm wide, 57.5 mm tall, and 72 mm deep, this contactor fits the standard S00 footprint and mounts via screw or snap-on onto a DIN rail. The IP20 front protection means it's suitable for enclosed panels where personnel don't contact live parts.
Switching ratings across voltages
The rated switching current drops with voltage: 10 A at 24 V, 6 A at 230 V, 3 A at 400 V, 2 A at 500 V, and 1 A at 690 V. The 125 V rated value appears as a separate spec line — likely the rated insulation voltage or a reference point for the contact block. The 6 kV surge voltage resistance (impulse withstand) aligns with pollution degree 3 environments, typical for industrial control panels without climate control.
Mechanical endurance and environmental range
Rated for 30 million mechanical switching operations, with shock resistance of 10g at 5 ms and 5g at 10 ms. The solid conductor terminals accept 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), or 2x 4 mm² — covering most control-wiring gauges used in panel building.
