Why Choose the ABB EF45-30?
The ABB EF45-30 (1SAX221001R1101) is a self-powered electronic overload relay offering precise and dependable protection for motors against overloads and phase failures. Functionally similar to a thermal overload relay, the EF45-30 provides enhanced accuracy and a wider setting range, along with a high operational temperature range and selectable trip classes (10E, 20E, 30E). This makes it suitable for a variety of standard motor applications in demanding environments. The EF45-30 simplifies motor protection with its self-powered design, eliminating the need for an external power supply. Its compact size, combined with direct contactor mounting, facilitates straightforward installation in panel building and industrial maintenance scenarios. Compliance with ATEX (from week 42, 2014) and IECEx (from week 15, 2017) certifications ensures safe operation in hazardous environments.
