Out if stock but available for backorder.

Square D by Schneider Electric BJA161251 is a moulded case circuit breaker (MCCB) within the PowerPacT BJA sub-range. It features a PowerPact B-Frame 125 TMD 1P 125A 600Y/347Vac 25kA I-line design with an I-line connection (A phase) and is rated for an impulse voltage of 8 kV. This MCCB has an IP40 degree of protection and supports a rated current of 125A with a rated voltage of 600Vac 600Y/347Vac. It offers mechanical durability of 20,000 operations at no load and mounts on I-line with line side isolated plug-on jaws plus a mechanical I-Line bracket mechanism for robust attachment. The unit is a 1-pole (1P) device with dimensions of 137 mm in height, 89 mm in depth, and 27 mm in width. It falls under utilisation category A and features over-current protection fixed at 125A, short-circuit hold current fixed at 1000A, and short-circuit trip current fixed at 1500A. The rated voltage for DC applications is 125Vdc, with a rated insulation voltage (Ui) of 800 V and a rated operating voltage (Ue) of 240 V. Protection functions include thermal protection for overload and magnetic protection for short-circuits, with a trip current rating of 125 AT. Its electrical durability with load is rated for 10,000 operations at 240Vac; In, and it has a frame current rating of 125 AF. The operating mode is manual toggle, and it has a short circuit breaking rating of 100kA at 240Vac, 65kA at 480Vac, 65kA at 480Y/277Vac, 25kA at 600Y/347Vac, and 50kA at 250Vdc, all according to UL489 standards. The trip unit type is thermal-magnetic (fixed) without a display.
