Description
TF Series Thermal Overload Relays
The ABB TF Series Thermal Overload Relays provide reliable protection for motors against overloads, ensuring the safety and longevity of both the motors and the connected systems. These relays are an essential component when used in combination with contactors, offering high-performance protection for motor-driven circuits.
Key Features:
Reliable Overload Protection: The TF series is designed to protect motors from thermal overloads by disconnecting the motor from the power supply when it operates beyond its rated capacity for too long.
Phase Failure Sensitivity: These relays are sensitive to phase loss, ensuring that motors operating on a three-phase system are protected even in the event of a single-phase failure.
Adjustable Settings: With adjustable current settings, the TF relays can be customized to fit the specific requirements of different motor types and sizes, allowing for flexible protection.
Temperature Compensation: The relays feature temperature compensation for environments with varying temperatures, maintaining reliable performance up to +70°C.
Stop and Test Function: The built-in stop and test functions allow for easy maintenance and monitoring, providing operators with a quick way to verify relay functionality.
Durable Design: Designed for a long operational life, these relays can withstand mechanical stress and continue functioning reliably over time.
Finger-Safe Housing (IP20): The TF series relays come with a finger-safe design, enhancing safety during installation and operation.
Applications:
Motor Protection: The TF Series is perfect for protecting three-phase motors from overloads and phase loss in various industrial applications.
Industrial Systems: Ideal for use in machinery, conveyor systems, HVAC systems, and other equipment requiring reliable overload protection.
Conclusion:
The ABB TF Series Thermal Overload Relays offer a robust and reliable solution for protecting motors in a wide range of industrial and commercial applications. With adjustable settings, phase failure sensitivity, and temperature compensation, these relays ensure the safety and longevity of your motor systems.
