What This SIRIUS S6 Contactor Brings to the Panel
The coil is rated 200–277 V AC, with a pickup dropout ratio of 0.8. Power connections take stranded cable from 25 to 120 mm², while the auxiliary/control terminals accept solid or stranded wire from 0.5 to 4 mm² (two conductors per terminal). That covers most motor feeds and control wiring in a single pass.
Clearance and Mounting — What You Need for Airflow and Arc Flash
That's the gap you need to maintain for arc quenching and heat dissipation — don't crowd it. The contactor itself measures 172 mm high by 140 mm wide by 170 mm deep. It's a size S6 frame, so plan your DIN-rail or backplate real estate accordingly. Mounting holes are 9 mm diameter, single hole per fixing point — standard M8 hardware fits.
Switching Performance and Mechanical Life
Electrical life depends on the duty class: AC-1 (resistive) allows up to 800 operations per hour, AC-3 (motor starting) up to 750 per hour, AC-4 (plugging/reversing) drops to 130 per hour. AC-2 (slip-ring motors) maxes at 300 per hour. Arcing time runs 10–15 ms. That's consistent with a standard power contactor — no fast-switching surprises.
Auxiliary Contacts and Coil Termination
This contactor includes an auxiliary switch block, so you get built-in status feedback without adding a separate module. The coil uses screw-type terminals — straightforward to wire with a standard screwdriver. Auxiliary contact ratings at various DC voltages: 10 A at 24 V, 2 A at 48 V, 2 A at 60 V, 1 A at 110 V. That covers most PLC input and relay interface loads.
