Bussmann 16021-3 Power Distribution Block, 175A, 600V

Bussmann 16021-3 Power Distribution Block

The Bussmann 16021-3 is a UL Recognized three-pole power distribution block designed for reliable, organized power splitting in industrial and commercial panels. Built from molded thermoplastic with high mechanical strength, it supports both copper and aluminum conductors and is suited for applications requiring 175A and 600V operation.

Why It Helps
This block provides a safe and efficient method for distributing power from one incoming conductor to multiple outgoing circuits. Its modular, interlocking design enables panel builders to create clean, scalable installations while maintaining UL 508A compliance. The backed-out captive screws streamline wiring and reduce installation time, especially in tight panel layouts.

Key Highlights

• Provides three-pole power distribution with one line-side port and six load-side ports per pole for flexible circuit expansion.
• Compatible with a wide range of copper and aluminum conductor sizes, allowing integration into new or retrofit panel designs.
• Molded thermoplastic housing with UL 94 V-0 flammability rating supports use in demanding industrial environments.
• Optional clear covers (sold separately) enhance touch safety and visibility of termination points.
• Designed for efficient mounting with elongated panel holes to align easily with existing layouts.

System Compatibility
Suitable for UL 508A industrial control panels, distribution cabinets, and electrical equipment requiring 175A and 600V distribution. Supports both copper and aluminum conductors within specified wire ranges.

Applications
Ideal for power distribution in motor control centers, HVAC systems, automation panels, renewable energy systems, and general industrial electrical installations. Its robust construction and UL recognition ensure dependable performance in harsh electrical environments.
