1492-50X Series B – Allen-Bradley – Power Terminal Block Copper 600V

Overview

The Allen-Bradley 1492-50X is a standard feed-through power distribution block from Rockwell Automation’s Bulletin 1492 terminal block family. Designed for industrial control and power distribution applications, this 3-pole block accommodates one line-side input and one load-side output, making it ideal for splicer and distribution tasks in electrical enclosures.

Key Features

• 3-Pole Configuration: Provides three independent circuits for power routing
• Feed-Through/Splicer Design: One opening on line side, one on load side for efficient wiring
• High Current Rating: 115-amp capacity supports substantial power distribution
• Wire Range #2–#14 AWG: Accepts copper conductors from #2 to #14 gauge
• 600V Rated: Suitable for standard industrial voltage applications
• Aluminum Construction: Corrosion-resistant material for cabinet mounting
• Tool-Free Installation: Requires only a flat-head screwdriver for assembly
