JGA262251

Square D by Schneider Electric JGA262251 is a Moulded Case Circuit Breaker (MCCB) within the PowerPacT JGA sub-range, featuring a PowerPact J-Frame 250 TMD 2P 225A 600Vac 18kA I-line AB 80% rated design. It offers a 2-pole (2P) configuration with thermal protection for overload and magnetic protection for short-circuit scenarios. The rated current is 225A, with a rated insulation voltage (Ui) of 750 V and a rated voltage (AC) of 600Vac 600Y/347Vac. This MCCB is designed for I-line connection (AB phases) and mounts on I-line with line side isolated plug-on jaws plus a mechanical I-Line bracket mechanism, ensuring a robust attachment. It has a net height of 191 mm, a net width of 105 mm, and a net depth of 127 mm. The degree of protection is IP40, and it operates manually via a toggle. Protection settings include over-current fixed at 225A and short-circuit pickup current adjustable between 1125A and 2250A. The rated operating voltage (Ue) is 690 V, with a rated impulse voltage (Uimp) of 8 kV. The trip current rating is 225 AT, with a frame current rating of 250 AF. Its short circuit breaking rating varies across voltages, with 65kA at 240Vac, 35kA at 480Vac and 480Y/277Vac, 18kA at 600Vac and 600Y/347Vac, and 20kA at 250Vdc and 500Vdc, all according to UL489 standards. The trip unit type is thermal-magnetic (adjustable) without a display, and it falls under utilisation category A.
