Description
The ABB OS100GJ03 3-Pole Fusible Disconnect Switch 100Amp J-Type is an electrical isolation and protection unit used to control power flow and safeguard connected equipment in electrical distribution systems. It provides a manual switching mechanism combined with fuse-based protection to interrupt current during overload or fault conditions. The unit is typically installed in panel assemblies where safe disconnection and circuit protection are required for downstream components. It supports stable electrical isolation and coordinated protection across connected load circuits in HVAC systems.
