Basler Electric produces a number of equivalent time overcurrent relays designed to replace existing GE-type IAC and Westinghouse-type CO time overcurrent relays. The BE1-50/51B relays provide a more versatile product than the ones to be replaced, because of the combination of connections, time overcurrent ranges, time characteristic and instantaneous overcurrent ranges available.
Basler’s latest Application Note PC-5051B02, explains how to select the appropriate BE1-50/51B model for IAC or CO replacement. It includes a table of the most popular IAC and CO characteristics and their equivalent BE1-50/51B characteristic switch selection position, as well as information on time overcurrent settings, reset characteristics, instantaneous overcurrent settings, connections, and case sizes.
The Application Note is downloadable from the Basler web site - http://www.basler.com/html/dwnapps.htm#PC5051B02
