1494R-N60

The Allen Bradley 1494R-N60 disconnect switch kit is essential for efficient electrical management and safety. It is classified as a non-fusible rotary disconnect switch with a robust 3-pole design meant to accommodate a disconnect capacity of 60 amps. This ensures it can handle substantial loads effectively. The unit maintains a rated isolation voltage of 660 volts, providing safe disconnection for maintenance and installation procedures.

Furthermore, the switch supports a continuous auxiliary contact current of 15 amps, increasing its versatility. The auxiliary contact adopts a double pole double throw (DPDT) configuration, allowing for diverse operational setups. Operating temperature is critical, and this model performs effectively in environments ranging from -35 to 40 degrees Celsius. For storage, it withstands more extreme temperatures from -40 to 65 degrees Celsius.

It is important to consider its altitude capabilities, as this switch is rated for use up to 2000 meters above sea level, broadening its application range. Constructed with a plastic body, the switch ensures lightweight durability while facilitating effective insulation. Contacts are made of copper and tin-plated for greater longevity and conductivity, with the mechanism made from zinc-plated steel, coupled with a bronze chromate finish for additional corrosion resistance. When tightening the wiring connections, a recommended torque of 35 to 45 lb.in should be applied to ensure secure fitting.
