EF45-45 Electronic Overload Relay
1 / 2
Manufacturer catalogue image
Product Description
RoHS Compliant
The EF45-45 is an electronic overload relay that requires no external supply, making it a self-supplied solution. It provides quick and dependable motor protection against overloads or phase failures. The relay is user-friendly, similar to a thermal overload relay, and is compatible with standard motor applications. Its wide setting range, high accuracy, and broad operational temperature range make it an attractive choice. Additionally, the EF45-45 allows for the selection of a trip class (10E, 20E, 30E).
The relay features temperature compensation, trip contact (NC), signal contact (NO), and the option to select automatic or manual reset. It also has a trip-free mechanism, STOP- and Test function, and a trip indication. The overload relays can be directly connected to the contactors. Single mounting kits are available as accessories. The EF19 and EF45 have ATEX and IECEx certification.
