Description
Black thermal overload relays are protective devices used in electrical systems to monitor the temperature of motors or other electrical equipment. They are designed to detect excessive heat caused by overcurrent or prolonged operation, which could lead to motor burnout or damage. When the temperature rises beyond a predetermined threshold, the relay trips and interrupts the electrical circuit, cutting off power to the motor and preventing potential damage. These relays are crucial components for ensuring the safety and proper functioning of electrical devices and are commonly used in industrial and commercial applications.
