Description
Designed for commercial power systems, the Eaton FDB3050 is a 3-pole, 50A molded case circuit breaker from the Series C F-Frame line. This bolt-on MCCB mounts into Eaton Series C and legacy Westinghouse panelboards. It includes load side lugs for wiring. For modern upgrades, it is replaced by the PDG23F0050TFFJ, which requires a retrofit kit for panelboard use. Rated 14kAIC at 480VAC, it utilizes a fixed thermal-magnetic trip unit. It is HACR and HID rated for specialized applications.Specifications
