Why Choose the EF19-0.32 [1SAX121001R1101]
The EF19-0.32 is a self-powered electronic overload relay requiring no external supply, designed to provide precise and rapid protection against motor overload and phase failure. It functions similarly to a thermal overload relay but offers enhanced accuracy, a broad setting range, and a wide operational temperature tolerance. The relay supports selectable trip classes (10E, 20E, 30E) to suit various motor protection requirements. Key features include temperature compensation, a normally closed trip contact, a normally open signal contact, selectable automatic or manual reset, a trip-free mechanism, and integrated STOP and Test functions with clear trip indication. The relay mounts directly onto contactors, with single mounting kits available as accessories. Both EF19 and EF45 models carry ATEX certification for units manufactured from week 42, 2014, and IECEx certification from week 15, 2017, ensuring suitability for hazardous environments.
