Square D by Schneider Electric HJA36150M74 is a Motor Protection Circuit Breaker (MPCB) within the PowerPacT HJA sub-range, designed for electronic motor protection, manual motor starting, and motor circuit protection. It features a PowerPact H-Frame 150 MCP (I) design, suitable for 3-pole (3P) configurations with a rated current of 150A and operates at a rated insulation voltage of 750 V. This MPCB supports a rated voltage of 600Y/347Vac for AC and 250Vdc for DC, with a degree of protection of IP40. It offers instantaneous protection (I) with over-current settings fixed at 150A and short-circuit protection adjustable between 348A and 1690A. The device is designed for I-line connections (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. Its dimensions are 163 mm in height, 104 mm in width, and 86 mm in depth. The operating mode is manual toggle, and it features a thermal-magnetic trip unit type without a display. The frame and trip current ratings are both 150A, with a short circuit breaking rating varying from 20kA at 250Vdc to 100kA at 240Vac according to UL489 standards. The rated operating voltage (Ue) is 690 V, and the rated impulse voltage (Uimp) is 8 kV, classified under utilisation category A.
