Siemens FXD63B080L is a molded case circuit breaker designed for providing reliable overcurrent and short-circuit protection in three-phase industrial power distribution systems. It features a thermal-magnetic trip unit with long-time and instantaneous functions, rated for 80A at 600V AC with an interrupting capacity of 35kA at 480V. The breaker is constructed in a compact FD frame with a feed-thru connection and measures 150mm x 250mm x 170mm (W x H x D), operating reliably within a temperature range of -25°C to 70°C. It complies with UL, CSA, and IEC standards and is compatible with various panel types including S4, P4, SPP, and F2. Typical applications include protecting feeders and branch circuits in industrial control panels, switchboards, and panelboards, accommodating copper wire from AWG 6 to 350 kcmil or aluminum from AWG 4 to 350 kcmil, and includes line and load side lugs (TA1FD350A).
