Contactors (Electromechanical)

A contactor is an electrical device used in many industries for controlling electrical power to a load or device. Within the contactor, switch electrodes close and open, often in response to a signal from an external controller.

The GDP403L24V contactor belongs to an assortment of contactors designed for direct current applications from 24 volts to 48 volts. It has full load current ratings of up to 40 amps and a thermal overload protection setting of 39 amps. The contactor is UL listed and fits mounting spaces of 56mm x 102mm.

Application fields

The GDP403L24V contactor can be used in the following application fields:

• Industrial control systems
• Emergency lighting systems
• UPS systems
• Battery charging systems
• Solar inverters

Working Principle

Inside the contactor, a pair of ferrous contacts is attached to one of two stationary frames: the main magnetic frame and the stationary frame. When an electrical current is applied to the main magnetic coil, it creates an electromagnetic field that attracts the ferrous contacts to the main magnetic frame, closing the circuit. When the current is interrupted, the pair of ferrous contacts returns back to its original position, breaking the circuit.

The GDP403L24V contactor is equipped with an LED pilot indicator that turns on whenever the contacts are closed. This indicator allows users to easily test and troubleshoot the contactor’s operation. The contactor also features a manual reset button to manually reset the contactor in the event of a power outage.

Advantages

The GDP403L24V contactor offers a number of advantages over traditional contactors. Its compact size makes it ideal for applications with limited space, while the full-load current ratings of up to 40 amps make it suitable for a wide range of applications. The LED pilot indicator and manual reset button make it easy to test and troubleshoot operation, while the thermal overload protection setting of 39 amps offers additional security and peace of mind.

The GDP403L24V contactor is an efficient and reliable solution for a wide range of direct current applications. Its compact design, full-load current ratings, LED pilot indicator, manual reset button, and thermal overload protection setting make it an ideal choice for many industries.
