HDA36040

Square D by Schneider Electric HDA36040 is a Moulded Case Circuit Breaker (MCCB) within the PowerPacT HDA sub-range. It features a PowerPact H-Frame 150 TMD design, suitable for 3-pole (3P) applications with a rated current of 40A. This breaker is designed for both AC and DC circuits, with a rated insulation voltage (Ui) of 750 V, rated voltage (AC) of 600Vac 600Y/347Vac, and a rated voltage (DC) of 250Vdc. It offers thermal and magnetic protection functions to guard against overload and short-circuit conditions. The HDA36040 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 163 mm, width of 104 mm, and depth of 86 mm, with a degree of protection rated at IP40. The operating mode is manual toggle, with over-current protection settings fixed at 40A and short-circuit protection settings fixed at 400A hold current and 850A trip current. The rated operating voltage (Ue) is 690 V, with a rated impulse voltage (Uimp) of 8 kV. Its frame current rating is 150 AF, and it has a short circuit breaking rating that varies depending on the voltage, up to 25kA at 240Vac according to UL489 standards. The trip unit type is thermal-magnetic (fixed), without a display, and it falls under utilisation category A.
