Out if stock but available for backorder.

Square D by Schneider Electric LGF36400U31XAAUOYH1Y029 is a Moulded Case Circuit Breaker (MCCB) within the PowerPacT LGF sub-range, designed with a factory-installed 24Vdc undervoltage (U/V) trip release coil and a factory-installed 1A/1B (1NO+1NC) auxiliary switch OF wire harness. This PowerPact L-Frame device supports a 600 Micrologic 3.3 (LI) 3P 400A configuration, suitable for 600Vac and 18kA busbar applications at 80% rating. It features a Term. nut kit for fixed busbar connections on both line and load sides, with three poles (3P) and offers long-time (L) and instantaneous (I) protection functions. The rated current is 400A, with a rated insulation voltage (Ui) of 750 V and a rated voltage (AC) of 600Vac 600Y/347Vac. It is designed for individual unit mount on plate, with dimensions of 382 mm in height, 153 mm in width, and 171 mm in depth, and has an IP40 degree of protection. The operating mode is manual toggle, with protection settings adjustable for overload (0.3...1 x In, 125A...400A) and short-circuit (1.5...12 x In, 600A...4800A). The control voltage (AC) specification indicates that the circuit breaker opens instantaneously when the undervoltage trip supply voltage drops between 35% and 70% of its rated control voltage, allowing closing when the supply voltage reaches 85% of rated control voltage. The rated operating voltage (Ue) is 690 V, with a rated impulse voltage (Uimp) of 8 kV. The trip current rating is 400 AT, with a frame current rating of 600 AF, and short circuit breaking ratings varying from 65kA at 240Vac to 20kA at 500Vdc, according to UL489 standards. The trip unit is an electronic Micrologic Standard 3.3 (LI) with no display, categorized under utilisation category A.
