Contactors (Electromechanical) are devices used to control and switch electric currents of various voltages through the use of electromagnetic fields. The GDP323L120V is a type of contactor that uses mechanical energy to switch currents. It is primarily used in motor control and other applications where a linear current must be switched on and off.

The GDP323L120V is rated at 30A at 120V and is UL rated. It is designed to control a line voltage up to 120V, and the NEMA 2 rating indicates its ability to withstand low temperatures and provides protection from shock. It has two coils; one to create the magnetic field, and one to control the contactors. The current required to activate or deactivate the contactor is known as the trip current.

The GDP323L120V uses a single contactor mechanism to make the switching action. The contactor is mechanically connected to two electrical control devices; the first is the control circuit, which is used to activate and deactivate the contactor from the switch. The second is the auxiliary circuit, which is used to provide feedback to the control circuit and the motor to ensure it is running correctly.

The GDP323L120V application fields are in the areas of motor control, HVAC systems, industrial control, home automation, and any other application where a linear current switch is needed. This contactor can be used to switch on and off heavy electrical appliances, for example a compressor motor, and it can be used to control lighting circuits, and is widely used in energy-saving systems.

The working principle of the GDP323L120V contactor is relatively simple. When the control coil is energized, it creates a magnetic field which engages the contactor, allowing current to flow through the circuit. As the contactor is engaged, the auxiliary coil checks the circuit to make sure it is working correctly and sends a feedback signal to the control coil. When the control coil is de-energized, the contactor disengages, breaking the circuit and stopping the current from flowing.

The GDP323L120V is a compact, yet powerful contactor and is designed for easy installation and reliable operation. It is suitable for a range of electrical applications and provides an economical and efficient way to switch current and control motors.
