Fuji Electric Co., Ltd. TK-ON TR13E Overload Relay

The Fuji Electric TK-ON TR13E is a 3-pole thermal overload relay that provides motor overload and phase-loss protection for three-phase motors, designed for direct mounting to Fuji SC series contactors and compatible with Fuji magnetic contactors and starters. It offers a current adjustment range of 1.4 to 2.2 A, supports a rated operational voltage up to 600 VAC, and uses a Class 10 trip characteristic with a mechanical trip flag indicator to clearly signal faults. The unit includes one normally open and one normally closed auxiliary contact, and the reset method can be manual or automatic depending on the installation. Ambient temperature compensation is built in, and the relay meets UL, CSA, and IEC standards. Commonly installed in motor control centers and industrial automation environments—such as motor starters, conveyors, pumps, compressors, fans, and HVAC systems—the TK-ON TR13E is suited for applications requiring reliable motor overload protection and phase-failure detection. It is used for motor protection within industrial machinery and production lines, including retrofits and maintenance tasks like motor starter repairs and overload-relay replacements. A common replacement is the TK-E02 Thermal Overload Relay.
