It carries a 96-127 VAC coil with screw-type terminals and includes an integrated auxiliary switch block. The MTBF of 75 a reflects a design meant to survive the nacelle — no up-tower swaps on a wind turbine pitch system when you spec this one right.
The coil operates at 96-127 VAC. Rated for AC-1 at 750 operations per hour and AC-3 at 750 ops/h, this contactor handles high-duty-cycle motor starting — conveyors, pumps, compressors cycling every few seconds. AC-4 drops to 130 ops/h, which is the plugging and inching limit; if you're reversing a load frequently, that 130 ops/h ceiling is the real constraint, not the AC-3 number. Arcing time of 10-15 ms is tight — the arc extinguishes fast inside the Size S6 arc chamber, which matters for contact life on inductive motor breaks.
Mounting and Wiring in the Panel
Fastens with screw fixing through a single 9 mm hole — not a DIN-rail snap-on, so plan for a drilled backplate. Main power terminals accept stranded wire from 25 to 120 mm² — that's the heavy lug range for motor feeders up to maybe 200-300 A depending on duty. Auxiliary and coil terminals take solid or stranded 0.5-1.5 mm², 0.75-2.5 mm², or max 0.75-4 mm² — standard control wiring with ferrules. The auxiliary switch is rated 10 A at 24 V, 2 A at 48 V, and 2 A at 60 V, so it handles PLC-level signals and small relay loads without an interposer. Dimensions: 172 mm high, 120 mm wide, 170 mm deep. The Size S6 frame is substantial; verify swing clearance for the arc chamber before you lay out the gland plate.
