ABB OT40F3 Disconnect Switch

The ABB OT40F3 Disconnect Switch is a type of manual disconnect switch meant for the HVAC system. It comes as a reliable system of safely isolating electrical circuits as well as permitting maintenance and service of equipment without exposure to live electrical parts. In its make-before-break configuration, the OT40F3 interrupts circuits, thereby eliminating any chance of electrical connection. This switch is normally installed in HVAC systems to help with safety while working on the system by isolating the power to the equipment. This makes it safe to use in electrical applications and has a long life in HVAC system applications.
