The AC-4 rating of 130 ops/h applies to plugging or inching duty where the motor is reversed or jogged under load. The coil draws a holding power that keeps dropout below 18 VAC, and the 115-130 ms closing time is consistent across both AC and DC operation — meaning it can be wired into a DC-switched control circuit without retiming the sequence.
The listed MTBF of 75 a reflects a design that is mature and field-proven. This figure is typical for a SIRIUS S6 contactor in a controlled electrical environment and supports a long maintenance interval in continuous-duty applications.
Panel integration and mechanical fit
The contactor measures 172 mm high, 120 mm wide, and 170 mm deep. The main power circuit accepts stranded cable from 25 to 120 mm², while the control terminals take solid or stranded wire up to 4 mm² per clamp. The auxiliary switch is included, so no separate add-on block is required for basic status feedback.
