Why Choose the EF19-1.0 [1SAX121001R1102]
The EF19-1.0 is a self-powered electronic overload relay requiring no external power supply. It provides fast, reliable motor protection against overload and phase failure, suitable for standard motor applications. Designed for ease of use comparable to thermal overload relays, it features a wide setting range, high accuracy, and operates effectively across a broad temperature range. Users can select trip classes 10E, 20E, or 30E to match specific protection requirements. Additional technical features include temperature compensation, normally closed trip contact, normally open signal contact, selectable automatic or manual reset, a 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 and IECEx certification, applicable to units manufactured from week 42, 2014 and week 15, 2017 respectively.
