RELIANCE 0-49002 Reliance Electric PC Tachometer Drive Board

Product Description:0-49002

Overview:

The RELIANCE 0-49002 is a thermal overload relay designed to prevent electric motors from overheating due to excessive current conditions. It serves as a vital component in motor control circuits, providing essential protection to enhance the longevity and reliability of motor-driven systems across various industrial applications.

Primary Functions:

• Overload Protection: The main function of the 0-49002 is to monitor the electrical current flowing through the motor and cut off power if the current exceeds a predetermined threshold for an extended period, thereby protecting the motor from thermal damage.
• Thermal Response Mechanism: It operates based on the principles of heat generation due to electrical current, using a bimetallic strip that bends with the temperature rise caused by overload conditions. When the strip bends to a certain point, it trips the relay, disconnecting the motor from the power source.
