SIRIUS S00 power contactor — panel-fit and motor ratings
Rated for 3 kW at 400 V, 3.5 kW at 500 V, and 4 kW at 690 V — the 690 V figure is the ceiling for this frame, making it suitable for 400 V line-fed motors with headroom or direct 690 V industrial networks. For reversing or plugging duty (AC-4), the contactor is rated 6.5 A at 400 V — a figure that governs service life under frequent switching, not the continuous motor rating. Main circuit connections use spring-loaded terminals accepting 2x (0.25 to 2.5 mm²) solid or stranded, or 2x (24 to 14) AWG — no screw torque to verify, which speeds panel wiring. Front and terminal protection is IP20, so the contactor is intended for enclosed panel installation where the enclosure provides the environmental seal.
Lifecycle and compliance posture
Coil operates at 50/60 Hz with a pickup range of 0.8 to 1.1 at 50 Hz and 0.85 to 1.1 at 60 Hz — ensure the control transformer is sized for inrush if multiple contactors pick up simultaneously. Auxiliary contact block side-mounting clearance is 6 mm at the side — enough for a standard block without crowding adjacent devices.
