G-SENS Thermal Overhead Relay

A G-SENS Thermal Overhead Relay is a crucial component in electrical systems, primarily designed to safeguard motors and other electrical equipment from damage caused by overloads and phase failures. Operating on a thermal principle, these relays monitor the current flowing through the circuit. When an abnormal increase in current occurs, leading to excessive heat generation, the relay's internal mechanism (often bimetallic strips or electronic sensors) detects this rise in temperature. Upon reaching a pre-set threshold, the relay "trips," interrupting the circuit and disconnecting the overloaded equipment, thereby preventing costly damage, overheating, and potential safety hazards.

These relays offer a robust and reliable solution for various industrial and commercial applications. They are commonly integrated into motor starter circuits to provide essential protection against conditions like prolonged overcurrent, short circuits, or single-phasing, which can lead to severe motor degradation or failure. G-SENS Thermal Overhead Relays typically feature adjustable current settings, allowing for precise calibration to match the specific full-load current of the protected motor. Many models also offer both manual and automatic reset options, along with test functions to ensure proper operation, making them versatile and indispensable for maintaining the longevity and efficiency of electrical machinery.
