HDF36150
Square D by Schneider Electric HDF36150 is a Moulded Case Circuit Breaker (MCCB) within the PowerPacT HDF sub-range, featuring a PowerPact H-Frame 150 TMD design. It is a 3-pole (3P) device with a rated current of 150A and offers thermal protection for overload and magnetic protection for short-circuit scenarios. This breaker is designed for a 600Vac/250Vdc operation with a 14kA busbar at 80% rating and includes a terminal nut kit for fixed busbar connections on both line and load sides. It has a rated insulation voltage (Ui) of 750 V, with AC and DC rated voltages of 600Vac 600Y/347Vac and 250Vdc, respectively. The unit is designed for individual mounting on a plate, with dimensions of 163 mm in height, 104 mm in width, and 86 mm in depth. It features an IP40 degree of protection, a toggle (manual) operating mode, and fixed protection settings for over-current at 150A and short-circuit hold and trip currents at 900A and 1700A, respectively. The rated operating voltage (Ue) is 690 V, with a rated impulse voltage (Uimp) of 8 kV. The trip current rating is 150 AT, with a frame current rating of 150 AF, and it has a short circuit breaking rating that varies depending on the voltage, including 25kA at 240Vac, 18kA at 480Vac and 480Y/277Vac, 14kA at 600Vac and 600Y/347Vac, and 20kA at 250Vdc, all in accordance with UL489. The trip unit type is thermal-magnetic (fixed) without a display, and it falls under utilisation category A.
