• Wide range of operating temperatures, for application in extreme environments;
• High quality construction, including excellent insulation to protect against electrical shock;
• Integral K switch for added safety;
• Automatic or manual reset;
• Vertical and horizontal mounting.

Working Principle

The 2900293 power relay is designed to switch current from an external circuit breaker or contacts of a motor or other device to be controlled. When current is detected on the external circuit the relay will switch on the device to be controlled and power will be supplied to it. When the current is turned off on the external circuit, the relay will switch the device back off and the power supply will be stopped.

The power relay has a set of contacts that are electrically insulated from one another. They carry the switching electricity and voltage of the device being controlled. The contacts are activated by a circuit breaker when the external circuit is energized or de-energized. When the circuit breaker is closed current will flow through the contact and switch the device on, and when the circuit breaker is open the device will switch off. In order for the power relay to work correctly, the external circuit must have appropriate service current and voltage.

Conclusion

The 2900293 power relay offers great versatility in applications requiring reliable switching of currents up to 10 amperes of AC or DC current. It is suitable for a variety of industrial, domestic and vehicle applications, and is designed to be used in a wide range of operating temperatures and features an integral K switch for additional safety. With its high quality construction and excellent insulation, it offers reliable and longlasting performance.
