SIRIUS Size S00 power contactor — 4 NO, spring terminals
It's rated for 4 kW at 400 V in AC-2 duty (slip-ring motor switching), and carries a 10 A rated value at 24 V for the magnet coil.
The 10 A at 24 V coil rating means the control circuit needs a supply capable of that inrush; holding power is 3.3 W DC, so once pulled in the coil draw drops sharply. Mechanical endurance is spec'd at 30 million operating cycles, which aligns with high-cycle applications like conveyor or pump stations. For coordination, Type 2 coordination requires a 20 A gL/gG fuse; Type 1 allows a 35 A gL/gG fuse. That's the overcurrent protection the installer needs to match for short-circuit ratings.
Spring-loaded terminals accept 2x (0.25 to 2.5 mm²) solid or stranded, or 2x (0.25 to 1.5 mm²) finely stranded with ferrule. AWG equivalents are 2x (24 to 14). The 72 mm depth, 45 mm width, and 60 mm height fit standard S00 panel layouts. Side-by-side mounting is allowed — no derating gap required — with a 6 mm clearance to adjacent devices at the side.
