840899107561

The Packard 840899107561 PR370 SPDT Switching Fan Relay is a versatile electromechanical component designed for automotive and industrial applications that require switching a fan based on temperature or other conditions. This particular relay model is characterized by its 24-volt coil voltage rating.

The Packard PR370 is a Single Pole Double Throw (SPDT) relay, meaning it has one common terminal (usually marked as "COM"), one normally open terminal (NO), and one normally closed terminal (NC). The fan circuit is connected to the NO terminal and the temperature sensing circuit to the NC terminal. When the temperature rises and the temperature sensor sends a signal to the relay coil, the relay closes the circuit, allowing electrical power to flow to the fan. Once the temperature goes back to normal, the relay opens the circuit, disconnecting the fan from the power source. This mechanism helps prolong the fan's life and ensures optimal fan performance.

This reliable switching fan relay is capable of handling up to 30 amperes of current, providing ample power for most fans. The contacts are silver, which offers excellent conductivity and ensures a reliable and efficient switching action. It functions reliably even in harsh conditions, with a temperature range of -20 C to 85 C, making it a reliable choice for automotive and industrial applications.

The dimensions of the Packard PR370 GD840899107561 are as follows: mounting center-to-center distance 25.4mm / 1inch, overall body height 13.4mm / 0.52 inch, overall body width 47mm /1.85 inches, and the body length 72.4mm /2.85 inches. The relay terminal cover is non-removable, ensuring a compact design that can easily be installed in limited space applications.

The Packard 840899107561 PR370 SPDT Switching Fan Relay's robust design and reliable performance make it an essential component for temperature-controlled systems in various applications, from automobiles to industrial equipment. With its 24-volt coil voltage rating, high current handling capability, and superior contact conductivity, it is a valuable addition to any project that requires controlled fan operation.
