Product Specifications
Product Description
CXR4 thermal overload relay is suitable for power system with AC 50Hz, rated operation voltage up to 660V and 1000V, in main circuit, current from 0.1A to 630A. It is used to protect AC 3 phase asynchronous motor against overload and phase failure. The current setting value can be regulated and the setting current values of many thermal elements are overlapping arrangement, for easy selecting by the customers from -25 to +55 air temperature as the products have temperature compensation. The relays have the test push-button for breaking NC contacts, operating indication and free trip characteristics. The items conform to IEC60947-4-1
Structure Features
The thermal relay is three-phase bimetal piece type and its break-off protection is differential motion structure; The temperature compensation equipment may protect the relay from the environment temperature change influence.
The thermal relay has the manual and automatic reset function, when reset manually; The relay s green indicator can show
The relay has red test button. When press the red button, the thermal relay s buckle is pulled off; When press the blue reset button, the contact closed frequently close, the relay restores to the original condition.
The relay has many installation methods, inserting into the contactor independently or inserting by the rail and most of thermal component s current is overlapping for users to select.
