ABB Electronic Overload Relay

ABB Overload Relays are essential protective devices used in motor control circuits to prevent motors from damage due to excessive current or overheating. These relays are designed to sense when an overload condition occurs in an electrical circuit and disconnect the power supply to the motor before any severe damage can take place. They offer reliable protection by continuously monitoring the current flow to the motor and tripping the circuit when necessary.

ABB Overload Relays are typically thermal or electronic, providing versatility for various applications. Thermal overload relays operate based on the heat generated by the current passing through the motor, while electronic overload relays offer more precise control and additional features, such as adjustable trip settings, phase failure protection, and communication capabilities.

These relays are compatible with ABB's contactors and motor starters, making them an integral part of a coordinated motor protection system. With easy installation and reliable performance, ABB Overload Relays ensure extended motor life, minimize downtime, and enhance overall system safety. They are commonly used in industries such as manufacturing, automation, HVAC, and more, where motor protection is critical for operational efficiency and safety.
