JDA36175

Square D by Schneider Electric JDA36175 is a Moulded Case Circuit Breaker (MCCB) from the PowerPacT JDA sub-range, featuring a PowerPact J-Frame 250 TMD 3P 175A 600Vac 14kA I-line ABC 80% rated design. It offers a 3-pole (3P) configuration with thermal protection for overload and magnetic protection for short-circuit scenarios. The rated current is 175A, 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 (ABC 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, with a degree of protection rated at IP40. The operating mode is manual toggle, with protection settings for over-current fixed at 175A and short-circuit pickup current adjustable between 875A and 1750A. The rated operating voltage (Ue) is 690 V, with a rated impulse voltage (Uimp) of 8 kV. The trip current rating is 175 AT, and the frame current rating is 250 AF. Its short circuit breaking rating varies according to voltage, with 25kA at 240Vac, 18kA at 480Vac and 480Y/277Vac, 14kA at 600Vac and 600Y/347Vac, and 20kA at 250Vdc, all under UL489. The trip unit type is thermal-magnetic (adjustable) without a display, and it falls under utilisation category A.
