The CC18/4SA220 contactors (electromechanical) are versatile relays, which are usually employed to switch electric circuits unrelated to any potential hazards and designed to handle circuits which require on/off operation at sensible frequency. This device is used as a high power switch controlled electrically, mechanically or thermally.

The CC18/4SA220 contactors are designed to handle currents up to 220A at 660V AC or DC. These contactors feature a robust thermal overload protection device which helps protect the device against overloading and they also have a robust built-in voltage and current limit for long-term operation.

The CC18/4SA220 contactors are the perfect choice for applications where continuous switching is required, such as switching off motors when they reach the set operating temperature or switching off fans when they reach a preset wind speed. This device can also be used in applications which require timed operation, such as switching off lighting or other electrical loads after a preset period of time.

The CC18/4SA220 contactors operate with a single-pole double-throw (SPDT) or two-pole double-throw (TPDT) type contact, depending on the type of switching application. This contactor also features a manual-reset function which can be used to reset the contactor after a failure. This ensures that the system is always under control.

The operation and working principle of the CC18/4SA220 contactors can be divided into four stages:

• Activation: The activation of the contactor is initiated by the receipt of an electrical signal from an external source, such as a push-button, a sensor, a timer, etc. This signal activates the control coils in the contactor.
• Current flow: The activated control coils generate a magnetic field, which attracts the movable contact and opens the circuit. Once open, the circuit is complete and the current flows through the contactor.
• Release: The release of the contactor is initiated by the receipt of an electrical signal from an external source. The release of the contactor is achieved by deactivating the control coils in the contactor, which in turn breaks the magnetic field.
• Reset: After the contactor has been released, the contactor is reset by a manual reset switch, which re-activates the control coils in the contactor.

The CC18/4SA220 contactors are suitable for applications such as switching off motors when they reach the set operating temperature, switching off fans when they reach a preset wind speed, switching off lighting or other electrical loads after a preset period of time, and controlling the operation of pumps, compressors, solenoid valves, and other electrical loads. With their safety features and simplified operation, they are a versatile and reliable solution for applications requiring switching.
