The Eaton FAZ-D5 is a 1-pole supplementary protector rated for 5 A in 277/400 VAC systems, designed for a 1-phase electrical configuration. This device is specified as a FAZ-D5 1SP supplementary protector with a 5 ampere rating and a 1 pole, 1 phase design, suitable for 277/400 VAC installations. As part of Eaton's FAZ family, it provides added protection for circuits operating at these voltages without introducing multi-pole complexity. The 5 A rating indicates the maximum current the protector is intended to carry under normal conditions before tripping in appropriate fault scenarios within 277/400 VAC environments.
