The Allen Bradley 1494U-LM31 serves an essential function as a lug connector within the 1494 series of disconnect switches. This component is made from aluminum, contributing to its overall durability and effectiveness in electrical applications. The unit has a disconnect switch rating of 30 to 100 amperes, suitable for handling both light and heavy current loads.

It features a multi-port design with a total of six ports, allowing for efficient wiring configurations. The product accommodates various conductor sizes; it is compatible with copper conductors ranging from 14 AWG to 4 AWG, and for copper-aluminum conductors, it accepts 12 AWG to 4 AWG and 10 AWG.

Each set includes three units, ideal for deployment in multi-pole applications, with a specification of three poles. The recommended torque settings for installation involve tightening conductors into the lug at 45 to 50 inch-pounds, while securing the lug to the terminal should be done at 40 to 60 inch-pounds to ensure solid connections.

With a dielectric strength of 2,200 volts maintained for one minute, this connector assures reliable insulation in operation. Additionally, the operational elevation capability of the 1494U-LM31 extends to 2,000 meters (approximately 6,561.68 feet) above sea level, catering to various installation scenarios.

The device operates effectively across a temperature range of -20°C to 60°C (-4°F to 140°F), making it adaptable to both indoor and outdoor environments. Together, these specifications highlight the 1494U-LM31's robust performance and versatility in electrical infrastructure.
