What this SIRIUS S00 contactor is and where it lands
The screw-type terminals accept 2x (0.5 to 1.5 mm²) solid or 2x (0.75 to 2.5 mm²) stranded, with a max of 2x (0.75 to 4 mm²) — that's the wiring envelope for the main current circuit. Side-by-side mounting is allowed — no derating gap required between units on the rail.
For Type 1 coordination (contactor may need replacement but the installation is safe), the fuse goes up to 35 A gL/gG. That's the difference between a fuse that protects the contactor itself versus one that only clears the fault.
Switching capacity across voltages — where this contactor works hardest
At 24 V rated value the contactor handles 10 A; at 230 V it's rated 6 A; at 400 V it drops to 3 A. For motor loads in AC-2 duty at 400 V, the rated power is 4 kW; in AC-4 duty at 400 V, the operating current is 8.5 A. The 690 V rating pushes 5.5 kW. That spread tells you this is a general-purpose S00 contactor — fine for small motors, resistive heaters, and lighting banks up to about 5.5 kW at higher line voltages. The 30 million mechanical cycles typical life means it outlasts most panel refreshes.
