An 100A 4 Pole Contactor is an electromagnetic control device used to connect or disconnect AC main circuits. It is widely applied in fields such as electric drive, household appliances, and industrial automation. Its core function is to control the “high-current main circuit” through a “low-current control circuit,” enabling the start-stop, forward-reverse rotation, and other control operations of high-power loads like motors and heaters.
100A 4 Pole Contactor Advantages
- Efficiently realizes “controlling large current with small current” and simplifies the control circuit.
- Built-in overload/undervoltage protection to enhance electrical safety.
- High load capacity + long service life, adaptable to complex working conditions.
- Supports multi-circuit and linkage control.
- Convenient operation and low maintenance cost.
Application Scenarios of AC Contactors
- Industrial Field (Core Application Scenario): Motor control (the most core scenario), high-power heating equipment control, and linkage control of automated production lines.
- Civil Field (Daily Electricity Scenario): Power control of large household appliances and household power distribution assistance.
- Commercial and Public Facility Field: Equipment control in commercial buildings, and public facilities & special scenarios.
