SIRIUS power contactor, size S00 — 24 V DC coil, spring-loaded terminals
The main circuit uses spring-loaded terminals accepting 2x (0.25 to 2.5 mm²) solid or stranded, which speeds panel wiring compared to screw terminals. Rated for switching at 24 V DC up to 10 A, and at 400 V AC in AC-2 duty up to 4 kW. The varistor surge suppressor is built into the coil circuit, so no external snubber is needed for inductive load switching. At 45 mm wide, it fits tightly on the rail — side-by-side mounting is permitted with 6 mm spacing to adjacent devices.
At 45 mm wide by 60 mm high by 114 mm deep, the S00 frame fits standard 35 mm DIN rail. The 114 mm depth is the dimension to check against enclosure depth and gland-plate clearance — it's the dimension that determines whether the contactor clears the back panel or door-mounted components. The 2000 m maximum operating altitude covers most installations outside high-altitude mining or mountain sites.
For type 2 coordination (contactor remains operational after a fault), the fuse is gL/gG 20 A. These are the values to pass to the panel designer for the short-circuit protection scheme. The contactor carries 2 instantaneous auxiliary contacts — these are the N.O./N.C. sets for feedback or interlocking. The auxiliary contact ratings at various voltages are listed: 10 A at 24 V, 2 A at 60 V, 1 A at 110 V, 0.3 A at 220 V, 6 A at 230 V, 3 A at 400 V (–).
