Overview
The Allen-Bradley 1492-PD31123 is an aluminum power distribution block designed to distribute power efficiently across multiple industrial circuits. This 3-pole unit features one line-side opening (accepts up to 500 kcmil/4 AWG conductors) and 12 load-side openings (accept 2–14 AWG conductors), making it ideal for control panels, motor starters, and power distribution applications where a single feed powers multiple loads.
Key Features
- 380 amp capacity with 600V AC/DC rated voltage
- 3-pole configuration with 1 line-side, 12 load-side openings
- Aluminum construction for durability and corrosion resistance
- Screw-type terminal connections for secure, reliable wiring
- Feeder spacing marked with wire range and tightening torque specifications
- Integrated SCCR (Short Circuit Current Rating) information marked on housing
Technical Specifications
This distribution block meets UL, CE, CSA, CCC, and KC certification standards, and operates reliably in temperatures up to 150°C. The aluminum housing measures 8.54″ wide × 5.50″ high × 3.23″ deep and weighs approximately 4.22 lbs.
Typical Applications
- Industrial motor control centers and distribution panels
- Power feed to multiple branch circuits and loads
- Control circuit power distribution in machinery and equipment
