Relays are a type of electrical device which is used to protect and control the operation of AC and DC electrical systems. These relays are known as RSEL-20R5W. RSEL-20R5W relays are power line filter modules which can be used to protect electrical systems from power line interference.

RSEL-20R5W Application Field

The RSEL-20R5W relay is mostly used to protect low voltage AC and DC systems from power line interference. It is mainly used in industrial, commercial, and residential applications. These relays can be used to protect industrial machinery, electrical appliances, and other sensitive equipment from power surges and power line noise. The RSEL-20R5W can also be used in computer systems, communication networks, and home automation systems.

RSEL-20R5W Working Principle

RSEL-20R5W relays are designed to detect signals in the power line and to actuate their associated contactor for protection and control purposes. The relays use a differential circuit to monitor both the current and voltage of the power line and to detect any potential variation or disturbance. Once the relays detect a power line disturbance, they trigger a contactor to protect the system from the interference. The relays also feature a self-reset function that allows them to reset after protection.

The RSEL-20R5W relays also provide a variety of monitoring and diagnostic features. These features enable operators to monitor and monitor the power line for any problems or potential disturbances. They also enable operators to test the efficiency of the relays. The relays also feature LED indicators which give operators indicator status on the relays’ operation.

Conclusion

RSEL-20R5W relays are power line filter modules used to protect AC and DC electrical systems from power line interference. These relays use a differential circuit to detect any potential variations or disturbances in the power line and to trigger an associated contactor for protection and control purposes. The relays also feature monitoring and diagnostic features along with LED indicators for monitoring and status. RSEL-20R5W relays are mostly used for industrial, commercial, and residential applications and can be used to protect industrial machinery, electrical appliances, and other sensitive equipment from power surges and power line noise.
