Contactors (Electromechanical)

K4001B5C2

Application Field

K4001B5C2 is a contactor that helps with the operation of heavy electric loads. It is used in various environments, including motor starters, power drive systems, machine tools, conveyor systems, welding equipment and lighting control.K4001B5C2 is ideal for medium voltage applications, with a maximum rated current of 75 A and a maximum voltage of 690 VAC. It is also suitable for low voltage applications, with a maximum rated current of 95 A. and a maximum voltage of 440 VAC.K4001B5C2 contactors are designed for high reliability and durability in harsh working conditions. The contactor construction includes a molded plastic base, screw terminals, silver-plated contact points and a top cover for easy dust protection.K4001B5C2 contactors are also available with a variety of mounting accessories, such as manual, push-type or motorized operation, and a range of electrical contacts for control. This makes them suitable for a wide range of applications.

Working Principle

K4001B5C2 contactors work on the principle of electromechanical switching. They are used to control the current flowing through the electrical circuits. The contactors are activated by an electromagnet that is energized by a low-voltage control circuit signal. When the control signal is applied, it energizes the electromagnet and allows a set of movable contacts (poles) within the contactor to move towards the fixed contacts (mains). The movable contacts of the contactor connect the mains to the control circuit when they come in contact, thus allowing the current to flow from the control circuit to the mains. When the control signal is removed, the spring-loaded mechanism of the contactor pushes the movable contacts away from the fixed contacts, thus cutting off the current flowing through the mains. This process ensures that the current through the mains is controlled by the control circuit.K4001B5C2 contactors are available in both single-pole and double-pole versions and can be used in series or parallel connection. The contactor is also available in 2-NO and 3-NO designs with auxiliary contacts for control of various loads.

Conclusion

K4001B5C2 contactors are electromechanical switches used to control high currents in heavy electrical applications. It is designed with an electromagnetic relay that is energized by a low-voltage control circuit and is suitable for both medium and low voltage operations. K4001B5C2 contactors are designed for high reliability and durability in harsh working conditions. The contactor is also available with a variety of mounting accessories, such as manual, push-type or motorized operation, and a range of electrical contacts for control. This makes them suitable for a wide range of applications.
