Internal oil-immersed, low-voltage secondary circuit breakers
ECI internal oil-immersed, low-voltage secondary circuit breakers are available for distribution transformers rated
10-167 kVA with secondary voltages of 120/240 or 240/480 single-phase. Some transformers rated 25 kVA
and all rated 37.5 kVA and above, single-phase, feature magnetic trip circuit breakers. Three-phase circuit breakers are
available from 15-150 kVA at 480 volts and below, and from 45-300 kVA at 480 volts.
