❓ Frequently Asked Questions

Q: The SS91011POOO has a coil voltage of 440V AC — what control supply is needed?

A: This SS91011POOO device requires a 440V AC control supply connected to the coil terminals (A1 and A2). For AC coils, ensure the control circuit voltage is stable — voltage drops below 85% of rated coil voltage can cause chatter and coil overheating. Always fit a surge suppressor across the coil when switching with a PLC or solid-state relay.

Q: How do I know the SS91011POOO replacement coil matches my contactor?

A: Match three things: (1) the contactor series and frame size stated for the SS91011POOO, (2) the coil voltage — the replacement must equal the control circuit voltage exactly, and (3) AC or DC supply type. Fitting a coil of the wrong voltage causes failure to pull in (too low) or coil burnout (too high). The original coil’s voltage is printed on its face — verify before ordering.

Q: What causes a contactor coil to fail and need replacement like the SS91011POOO?

A: The most common causes are: sustained undervoltage (coil hums and overheats while failing to seal the magnetic circuit), overvoltage, voltage spikes from nearby switching inductive loads, dust or rust on the magnet faces preventing full closure (coil draws inrush current continuously), and simple ageing of the insulation. If coils fail repeatedly, fit a surge suppressor and check the control supply voltage stability before fitting the new coil.
