Why Choose the EF19-6.3 [1SAX121001R1104]
The EF19-6.3 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 use comparable to thermal overload relays, it is compatible with standard motor control applications. Key features include a broad setting range, precise current detection, an extended operating temperature range, and selectable trip classes (10E, 20E, 30E) to suit various motor protection requirements. Additional functionalities comprise temperature compensation, normally closed trip contacts, normally open signal contacts, selectable automatic or manual reset, a trip-free mechanism, STOP and test functions, plus clear trip indication. These relays mount directly onto contactors, with single mounting kits available as accessories. Both the EF19 and EF45 series hold ATEX and IECEx certifications, applicable to units manufactured from week 42, 2014 (ATEX) and week 15, 2017 (IECEx) respectively.
