1494V-DJ644-A

The 1494V-DJ644-A from Allen Bradley is specifically engineered as a variable depth flange-mounted disconnect switch. This unit is rated to operate at a voltage of 600 V and can handle a maximum current of 400 A. The fuse clips are compliant with Class J standards and can accommodate fuse currents ranging from 30 to 600 A, thereby ensuring flexibility in application. Notably, the switch is designed for a long connecting rod, allowing for varied depth installations.

This disconnect switch performs within a broad operating temperature spectrum, functioning effectively between -35°C to 40°C, and is capable of storage at temperatures as low as -40°C and as high as 65°C. Its design also allows for successful operation at altitudes up to 2000 meters. Relative humidity levels of 90% at 20°C and 50% at 40°C can be tolerated without impacting its performance.

Constructed from phenolic material, the switch body ensures durability, while the contacts consist of copper that is tin plated, enhancing conductivity. The switch holds a dielectric strength rating of 2200 V for a duration of one minute, which bolsters its protective capabilities. Furthermore, it is built for a significant operational lifespan, with an expected electrical life of 6000 operations when used at the rated current. Overall, the 1494V-DJ644-A switch combines robust construction with a reliable performance profile, suitable for demanding industrial applications.
