Why Choose the EF65-56 [1SAX331001R1102]
The EF65 is a self-powered electronic overload relay requiring no external supply, providing reliable and rapid motor protection against overload and phase failure. Designed for straightforward installation and operation, it is compatible with standard motor applications and offers a broad current setting range with high accuracy. The relay supports trip class selection (10E, 20E, 30E) and operates effectively across a wide temperature range. Key features include 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 EF65 mounts directly onto contactors, with single mounting kits available as accessories. The EF65, along with EF96 and EF146 models, holds ATEX certification (applicable from week 42, 2014 production) and IECEx certification (from week 15, 2017 production), ensuring suitability for hazardous environments.
