Description
The ABB OT40FT3 3-Pole Non-Fused Switch Disconnector 40A 750V is a manually operated isolated part used in low-voltage electrical distribution systems to disconnect electrical loads for operational control in HVAC systems. It is placed in motor control units, switchboards, and control panels where stable control of circuits is required. It operates as a main or local disconnect switch, allowing technicians to remove equipment such as compressors, fans, or control assemblies. It provides a visible break in the circuit without fusing capability, ensuring separation of power in accordance with standard electrical protection practices.
