System Components

OutBack AC Breakers

Hydraulic-Magnetic type breakers that are DIN rail “snap-in” mountable and can be used for in- put, output or load circuits. 1/2" (13 mm) wide.

OutBack DC Breakers

Panel mounted Hydralic-Magnetic type breakers which can be used for DC sources, inverters or load circuits. 3/4" (18 mm) wide.

OutBack PV Ground Fault

Protection System

The OBDC-GFP/2 is required by the NEC for PV arrays mounted on residential dwelling roofs. It can be used with the PS2DC, PS4DC or PS1. An OBDC-GFP/2 protects wiring and sys- tem components for one or two PV arrays: dual 80 amp PV circuits 150 VDC max VOC. The OBDC-GFP/2 system includes the GFP unit, a ground bus bar, neutral and ground connection wiring and mounting hardware.
