DP4R60E40

Contactors (Solid State) are instrumental in the field of electrical power distribution providing flexible control in applications where electric current places equipment and personnel at risk of harm. DP4R60E40 is one such contactor, used widely due to its flexibility and reliability. This article dives into the application field and working principle of DP4R60E40 contactors.

Applications Field

DP4R60E40 contactors are especially suited for extreme conditions of operation such as, for example, high ambient temperature, high humidity, presence of contaminants or corrosive gases, environmental stress, vibration, mechanical shocks and continuous operation. The contactors provide high switching capacity and isolation duty, even under tough conditions.

The contactors provide high switching capacity up to 8kA and are rated for 24VAC to 600VAC operation. They are a perfect choice for a wide variety of applications ranging from industrial machinery, water and waste treatment plants, residential lighting fixtures and appliances, data centers, security systems, elevators, retail outlets, and many more.

Working Principle

DP4R60E40 contactors use solid-state switching technology to control electrical current. Their robust construction and low profile allows for easy installation in tight spaces. Furthermore, their low-resistance and low-temperature electrolytic copper contacts ensure that there is minimal arcing and minimal heat dissipation.

The contactors operate by switching two metal contacts closed or open when a current is passed through the contactor. This is achieved by a solid-state switch which is activated when a current is applied. The switch’s contacts keep the circuit open or closed, while the current passes through the contactor and is either switched off or on. When the current is off, the contactor opens and interrupts the circuit, preventing current from flowing. When the current is on, the contactor closes and allows the circuit to complete, allowing current to flow.

DP4R60E40 contactors have the advantage of being able to switch between two different ranges of current, from 3-8kA. This is beneficial for applications which require varying levels of current; switching from one range to another is much simpler with a contactor than it would be with a mechanical switch.

Conclusion

DP4R60E40 contactors are a reliable and flexible solution for controlling electrical current in multiple applications. These contactors offer high switching capacity up to 8kA and are rated for 24VAC to 600VAC operation. Furthermore, they are capable of switching between different ranges of current, which makes them ideal for applications with varying current requirements. The robust construction and low profile of DP4R60E40 contactors make them suitable for even extreme environments.
