What is a Modular Contactor?

A modular contactor, also known as a modular relay or a modular switchgear, is an electrical switching device, an electrical component used to control the operation of a circuit.

Modular contactors are usually designed to be mounted on a DIN rail or within an electrical panel.

What is the composition of the modular contactor?

Modular contactors consist of coils, contacts and a mechanical switching mechanism.

How does a modular contactor work?

When a control signal is applied, the coil is energized, generating a magnetic field that attracts or releases the contacts.

Modular contactors are used to control the flow or interruption of the current in the circuit.

Application of modular contactor

These modular contactors are typically used in applications that require switching high currents or remotely controlling electrical loads, and are commonly used in industrial and commercial environments to control lighting systems, HVAC (heating and ventilation systems), motors, pumps, and other electrical equipment.
