Modular contactors are a group of devices - actuators, which allow for economical and safe control of the current flow in electrical installations. They are used, among others, in control systems for heating, lighting, ventilation and electric motor power supply systems.
A modular contactor is a type of mechanical connector that is mounted on a rail in control cabinets. The design of the contactor consists of working contacts - one or more pairs, a coil and an electromagnet.
