SIRIUS S00 power contactor — panel-fit and switching capability
At 45 mm wide by 57.5 mm tall and 114 mm deep, it fits the compact S00 footprint that leaves room for auxiliary contact blocks alongside. Rated for AC-2 duty at 4 kW and AC-4 at 8.5 A, both at 400 V, this contactor handles reversing or plugging motor loads where the current doesn't drop to zero between operations. DC switching capability is present across several voltages: 10 A at 24 V, 2 A at 60 V, 1 A at 110 V, and 0.3 A at 220 V. That covers most control-circuit and small DC-motor applications without an interposing relay.
Screw-type terminals on the main current circuit accept 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), or up to 2x (0.75 to 4 mm²) solid or stranded conductors. AWG equivalents are 2x (20 to 16), 2x (18 to 14), and 1x 12. The terminals are IP20 finger-safe, so the panel doesn't require additional shrouding on the contactor itself.
This lets the panel designer choose between protection level and fuse economy.
