Contactors (Electromechanical)

Contactors (Electromechanical) are switch devices used for controlling electrical circuits by opening and closing contacts, usually controlled by an electromagnet. The 4-1618391-1 is a single step Contactors designed for controlling electronic circuits of various AC and DC voltages. This contactor features a robust design and delivers reliable service.

Application Field for 4-1618391-1 Contactor

The 4-1618391-1 Contactor is designed for controlling AC and DC electrical circuits, including those found in motor starters, HVAC equipment, refrigeration, lighting, and other industrial applications. This contactor can be used in systems up to 600V, with a current rating of 30A with resistive load, and offers reliable switching action and high contact performance.

The Working Principle of 4-1618391-1 Contactor

The 4-1618391-1 contactor consists of an electromagnet, a set of contact bails, and a coil. The coil is energized when power is supplied to it, and this energizing creates a magnetic field around the electromagnet’s core. This magnetic field draws the contact bails towards the core, causing them to engage and connecting the electrical circuit. When the coil’s power supply is removed, the contact bails are pulled away by the returning electromagnet’s core, breaking the circuit.

Conclusion

The 4-1618391-1 Contactor is a single-step contactor designed for controlling AC and DC electrical circuits, with a current rating of up to 30A. It is designed to offer reliable switching action and high contact performance in various industrial applications. This contactor works by the energizing of its coil, which creates a magnetic field which pulls the contact bails closed, connecting the circuit. When the coil’s power supply is removed, the contact bails are pulled away and the circuit is broken.
