SIRIUS S00 auxiliary contactor — 2 NO + 2 NC, screw and snap-on mounting
It carries 2 normally-open and 2 normally-closed instantaneous contacts, with no leading, lagging, delayed, or make-before-break switching — straight 2 NO + 2 NC. Rated 10 A at 24 V, 6 A at 230 V, and 3 A at 400 V, with a surge voltage resistance of 6 kV and pollution degree 3 — suitable for industrial control panels where contactors and relays share a DIN rail.
Wire termination and contact ratings
Terminals accept solid conductors: 2x (0.5...1.5 mm²), 2x (0.75...2.5 mm²), and 2x 4 mm² — covers the common control-wire gauges for panel building. Contact reliability is rated at one incorrect switching operation per 100 million cycles at 17 V, 1 mA, so it handles low-level logic signals without stuttering. The AC-15 / DC-13 switching capacity is defined by the voltage-specific current ratings: 10 A at 24 V, 1 A at 110 V, 0.27 A at 220 V, 6 A at 230 V, 3 A at 400 V, 2 A at 500 V, 1 A at 690 V. The 50 Hz coil pickup range is 0.8...1.1; at 60 Hz it's 0.85...1.1.
The auxiliary switch extension is available (product extension auxiliary switch: yes), so you can add more contact blocks on the side if the 2 NO + 2 NC count isn't enough. Verify the coil voltage variant matches your control circuit — the 24 V 50/60 Hz coil is the standard here.
