Why Choose the EF19-2.7 [1SAX121001R1103]
The EF19-2.7 is a self-powered electronic overload relay requiring no external supply, providing dependable and rapid motor protection against overload and phase failure. Designed for straightforward installation and operation similar to thermal overload relays, it is compatible with standard motor control applications. Key features include a broad setting range, precise current measurement, extended operational temperature tolerance, and selectable trip classes (10E, 20E, 30E) to suit various motor protection requirements. Additional functionalities comprise temperature compensation, normally closed trip contact, normally open signal contact, selectable automatic or manual reset, trip-free mechanism, STOP and Test functions, and clear trip indication. The relay mounts directly onto contactors, with single mounting kits available as accessories. Both EF19 and EF45 models hold ATEX certification for units manufactured from week 42, 2014, and IECEx certification from week 15, 2017, ensuring suitability for hazardous environments.
