Square D EGB36090 Molded Case Circuit Breaker

Square D EGB36090 Molded Case Circuit Breaker is a 3-pole, 90-ampere MCCB from Schneider Electric's Square D EGB family, rated for up to 600 volts and designed for three-phase protection in industrial and commercial distribution panels. It features thermal-magnetic trip protection and bolt-on mounting compatible with Square D enclosures, with terminal arrangements optimized for straightforward wiring and secure installation. The unit lists an interrupting rating of 35 kA at 480 V, reflecting its capability to interrupt fault currents in medium-size circuits, while the 3-pole design ensures balanced protection across all phases. As part of the Square D lineup, the EGB36090 is intended for feeders, motor circuits, and other equipment in systems requiring 90 A overcurrent protection within a 600 V class, and it supports replacement in existing installations that use the EGB family.
