840899107516

The Packard 840899107516 Switching Relay, also known as model PR340, is a versatile and reliable electrical component designed for various switching applications. This relay is specifically engineered to handle 24 volts coil power, making it an ideal choice for low-voltage systems.

The PR340 Switching Relay is built with a robust construction, ensuring durability and reliability under heavy usage. It features a contact rating of 10A at 250V AC or 30V DC, providing sufficient power to handle most switching requirements. The contact material used is silver alloy, which offers excellent conductivity and resistance to wear, ensuring a long lifespan.

This relay comes with a coil resistance of 150 ohms and a contact bounce time of less than 10 milliseconds. The bounce time refers to the time it takes for the contacts to fully close or open after being activated, ensuring smooth and stable switching operations.

The PR340 Switching Relay is designed with a latching mechanism, which means it stays in the last position it was switched to until it is manually switched again. This feature is useful for applications where the switching state needs to be maintained even when power is temporarily disconnected.

This relay is also designed with an over-temperature protection feature, which automatically disconnects the coil power if the relay gets too hot, preventing damage to the component. It also features a built-in LED indicator, which illuminates when the relay is activated, making it easy to monitor the switching status.

The PR340 Switching Relay from Packard is suitable for various industrial, automotive, and electrical applications, including power distribution, HVAC systems, and control systems. Its compact size, measuring 3.5 x 2.3 x 1.3 inches, makes it easy to install and integrate into different systems. With its robust construction, reliable performance, and versatile features, this switching relay is an excellent investment for any electrical project or application.
