SIRIUS Contactor Relay for Auxiliary Switching
It provides 3 normally open (NO) and 1 normally closed (NC) auxiliary contacts, rated for AC control voltage. The relay mounts on a 35 mm DIN rail via screw or snap-on fastening, with a compact footprint of 73 mm depth, 45 mm width, and 57.5 mm height — sized for dense panel layouts where every millimeter of rail space counts.
Current Ratings Across Voltages
The contact ratings vary by voltage and duty: 6 A at 24 V, 3 A at 110 V, 1.2 A at 220 V, 10 A at 230 V, 3 A at 400 V, and 1 A at 690 V. The AC-12 maximum operational current is 6 A, suitable for resistive and lightly inductive loads in control panels.
Coil and Environmental Specifications
The AC coil draws 37 VA pick-up power and 5.7 VA holding power at a power factor of 0.8. It operates over a voltage tolerance of 0.8 to 1.1 times nominal at 50 Hz and 0.85 to 1.1 at 60 Hz. Surge voltage resistance is 6 kV, and the contact reliability is 1 faulty switching per 100 million operations at 17 V, 1 mA — a strong figure for low-energy signal circuits.
Mounting and Wiring Flexibility
Wiring accepts solid or stranded conductors: 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), or 2x 4 mm², with equivalent AWG sizes 2x (20 to 16), 2x (18 to 14), and 2x 12. Finely stranded wires with core-end processing are also supported.
