Product details

SIRIUS auxiliary contactor, 4 NO, S00 frame

The coil is rated for 230 V at both 50 Hz and 60 Hz, with an operating range of 0.8 to 1.1 times rated voltage at 50 Hz and 0.85 to 1.1 at 60 Hz.

The 4 NO contact arrangement provides four independent normally-open auxiliary circuits. The 6 kV rated surge voltage resistance withstands impulse voltages typical of industrial control panels. The IP20 front protection means the front is finger-safe, but terminals are not protected against water ingress.

Mounting is via screw or snap-on onto a DIN rail — the S00 footprint is 45 mm wide, 57.5 mm high, and 111 mm deep. Solid conductors accepted are 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), or 2x 4 mm² — the dual-wire termination is useful for daisy-chaining control wiring without additional terminal blocks. Shock resistance is rated at 10g for 5 ms and 5g for 10 ms, suitable for installation near vibrating equipment like contactors or motor starters on the same rail.
