The thermal overload relay is made of high-quality alloy material, large-area binding post, independent terminal and screw fixing, which is convenient and quick to install.

The test button of the thermal overload relay, that is, the button that tests whether the thermal overload relay can operate, press this button, which is equal to whether the operation state of the thermal overload relay is normal when it is dropped or overcurrent.

Thermal overload relays are used to protect phase loss during motor overload, phase failure protection, manual and automatic reset, temperature compensation, tripping indication, stop button, etc.

Good Durability Material: This Electric Overload Relay is made of quality material, long service time. Used for protecting the phase break when the electric motor is overload

Ideal Protection Tool for Motor: This series of thermal overload relays is suitable for overload and phase failure protection of AC motors with long-term operation or intermittent long-term operation of AC 50Hz/60Hz, voltage to 690V

Multi-functions Allows Working: The thermal relay has phase failure protection, temperature compensation, motion indication, automatic and manual reset, and stop function
