Enclosed Non-Fused Switch-disconnectors 16 to 800 Amperes High performance compact solutions. OT series isolating switch for a variety of different applications, such as mechanical equipment, power distribution, switchgear, motor control center and photovoltaic power generation system. Range: • 20-80A UL508 • 30-800A UL98 • 600V max • HP ratings available up to 800A • Up to 200kA with fuses • Up to 20,000 operations Features and benefits: • Safer to use: Incorporating lockout/ tagout provisions is crucial for safe work • Improves ROI: OT switches have longer lifetime, thanks to the high mechanical endurance (Up to 20 000 operating cycles) • Safer: OT switches have visible contacts for 100A and above for increasing safety by seeing the contact position. We also provide door interlock feature where the door cannot be opened when the external handle is padlocked in the OFF-position. • Superior performance: OT switches unique Knife contact solution provide a very short current path, which allows the size of the contact construction to be very small. As a result, lower power loss and less heat compared to traditional design solutions. ABB switch-disconnectors are designed, built and tested for the best possible performance. They are designed to be virtually maintenance free across their entire extended lifespan and offer reliable performance in any and all possible circumstances. Durability has been ensured by testing switches against the IEC60947- 3, UL508, UL98 and CSA standards. Whether it is for demanding motor load disconnecting or simple isolation applications, we offer a market-leading product portfolio of switch-disconnectors ranging from 16 to 2000 Amperes. Thanks to their modular structure, our switches can serve both manual and motorized applications. These devices also help create purpose-built solutions from directly busbar mountable wide phase models to floor mounted earthing switches. All this with the highest level of performance and reliability. Applications: Switching of mixed loads for basically any application: • Control panels • Low-voltage switchgears • Low-voltage substations • Distribution panels in buildings • Motor disconnecting in various applications: o Machine builders o Motor control centers o HVAC, pumps and conveyors • Heavy industries: o Pulp & Paper o Food & Beverage o Refining & petrochemicals • Power generation and renewables: o Wind turbines o Solar plants o Generating sets o Power plants
