Out if stock but available for backorder.

Square D by Schneider Electric HGA260251 is a Moulded Case Circuit Breaker (MCCB) within the PowerPacT HGA sub-range, designed as a PowerPact H-Frame 150 TMD 2P 25A 600Vac/500Vdc 18kA I-line AB with an 80% rating. It features a 2-pole (2P) configuration with I-line connection (AB phases) for mounting. This MCCB offers thermal protection for overload scenarios and magnetic protection against short-circuits, with a rated current of 25A. The rated insulation voltage (Ui) is 750 V, with AC rated voltages of 600Vac and 600Y/347Vac, and a DC rated voltage of 500Vdc. It mounts on I-line with line side isolated plug-on jaws plus a mechanical I-Line bracket mechanism, ensuring a robust attachment. The net dimensions are 163 mm in height, 104 mm in width, and 86 mm in depth, with an IP40 degree of protection. Operation is manual via a toggle, with over-current protection fixed at 25A and short-circuit protection settings fixed at 350A for hold current and 750A for trip current. The rated operating voltage (Ue) is 690 V, with a rated impulse voltage (Uimp) of 8 kV. The trip current rating is 25 AT, with a frame current rating of 150 AF. Short circuit breaking ratings include 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 (fixed) without a display, and it falls under utilisation category A.
