Basler Develops Overcurrent Relay Replacements
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 combination of connections, time overcurrent ranges, time characteristic and instantaneous overcurrent ranges.
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.
