Square D by Schneider Electric BDA140451 is a Moulded Case Circuit Breaker (MCCB) within the PowerPacT BDA sub-range, designed with a PowerPact B-Frame 100 TMD 1P 45A 480Y/277Vac 18kA I-line. It features an I-line connection for the A phase and offers a degree of protection rated at IP40. The rated current for this device is 45A, with a rated voltage for AC applications at 480Vac and 480Y/277Vac. It has a 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. This 1-pole (1P) circuit breaker has dimensions of 137 mm in height, 89 mm in depth, and 27 mm in width. It falls under utilisation category A and provides over-current protection fixed at 45A, short-circuit hold current protection fixed at 400A, and short-circuit trip current protection fixed at 600A. 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. It offers thermal protection for overload and magnetic protection for short-circuits, with a trip current rating of 45 AT. The electrical durability with load is 10,000 operations at 240Vac; In. The frame current rating is 100 AF, and it operates via a toggle (manual) mechanism. The short circuit breaking rating varies with the voltage, being 25kA at 240Vac, 18kA at both 480Vac and 480Y/277Vac, 14kA at 600Y/347Vac, and 10kA at 250Vdc, all according to UL489 standards. The trip unit type is thermal-magnetic (fixed) with no display.
