Electromechanical Contactors are electrical devices used for controlling an electrical circuit with a simple mechanical action. The CC75/4SA240 is a specifically designed contactor to operate in high voltage applications requiring two independent fields for switching functions. It is comprised of two separate fields working together to control the on/off state of a circuit.

The first field is the main contactor which operates on the AC side. It is composed of a cylindrical contactor with a movable armature. When the armature is actuated, the contacts are opened or closed to switch the circuit. The contactor is actuated by a solenoid coil powered by the AC source.

The second field is the auxiliary contactor. This operates on the DC side and is composed of a strip contact with a spring-loaded armature. It is actuated by a DC source to make or break contact. It is important to note that the auxiliary contactor can be used to interrupt the circuit from the AC side even when the main contactor is closed.

The CC75/4SA240 contactor is designed for high voltage applications up to 6.6 kVac. It has a rated operational voltage of 440 VAC and a peak voltage of 600 VAC. It is fitted with an indicator light that shows when the contactor is engaged, and it can be manually operated for testing purposes. The contactors are designed with a spring-loaded, temperature compensated operating mechanism that ensures reliable operation at all temperatures.

The CC75/4SA240 contactor is essential in applications such as motor control. The device can be used to switch a motor on or off using the two separate fields. When the motor is not in use, the main contactor is engaged while the auxiliary contactor is open. When it is time to switch the motor on, the main contactor is opened and the auxiliary contactor is engaged. This ensures that the power is not interrupted during the transition.

The CC75/4SA240 contactor is also used in resistive applications, such as power supplies, incandescent lighting, and other low power applications. The device is used to switch the circuit to allow for the current to flow and power the device. Again, the two fields work together to ensure that the power is not interrupted while the circuit is switched.

The CC75/4SA240 contactor is a reliable device, designed for use in applications requiring two independent fields for switching purposes. It is rated for operation up to 6.6 kVac, and provides reliable operation at its rated voltage. The device is used in motor control and other resistance applications to ensure the safe and reliable switching of circuits. Its two independent fields ensure that the power is not interrupted while the circuit is switched.
