A contactor is an electrically operated switch used to make and break power circuits under load, most commonly to start and stop three-phase motors. Energising the control coil closes the main poles; de-energising it opens them, so the contactor can be driven from a control circuit, PLC or overload relay.
With a 95 A AC-3 rating and an integral 1 NO + 1 NC auxiliary, the NC1-9511 suits direct-on-line motor starters, control panels and general power switching where dependable, standards-compliant operation is required.
Typical Applications
- Direct-on-line (DOL) motor starters.
- Motor control centres and control panels.
- Pump, fan and compressor control.
- Heating and lighting loads (AC-1).
- Automation and machinery control circuits.
- General three-phase power switching.
