Square D NX361000G – 1000A 3 Pole Molded Case Circuit Breaker Place Order

Engineered with a Micrologic Series B trip unit, this 1000A breaker delivers precise LSIG protection for industrial distribution networks. It mounts into Square D I-Line panelboards. For modern upgrades, it is replaced by the PowerPact PLA34100U63A (note the newer model’s lower 25kA rating at 600V). Boasting a 100kAIC interrupt capacity at 480V, the solid-state design ensures true RMS sensing for accurate overcurrent response.
