Why Choose the EF205-210 [1SAX531001R1101]
The EF205-210 is a self-powered electronic overload relay requiring no external supply, designed to deliver precise and rapid motor protection against overload and phase failure. It combines the simplicity of thermal overload relays with enhanced functionality, making it suitable for standard motor control applications. Key technical features include a broad current setting range, high measurement accuracy, and a wide operating temperature tolerance. Users can select trip classes (10E, 20E, 30E) to match specific motor protection requirements. Additional functionalities comprise temperature compensation, a normally closed trip contact, a normally open signal contact, selectable automatic or manual reset, a trip-free mechanism, as well as STOP and test functions with clear trip indication. The EF205 series connects directly to contactors, ensuring seamless integration. It also holds ATEX certification for units manufactured from week 42, 2014, and IECEx certification from week 15, 2017, confirming suitability for hazardous environments.
