Overview
The Allen-Bradley 140M-C-W454N compact busbar is a purpose-built distribution accessory for medium-voltage industrial control systems. This compact busbar connects directly to 140M-C and 140M-D series molded case circuit breakers, simplifying branch circuit installation and reducing panel wiring complexity. Rated for 64 A continuous current at 690 V, it handles 3-phase power applications in manufacturing, process control, and OEM equipment.
Key Features
- 64 A Continuous Current Rating — handles moderate-load branch circuits without derating
- 690 V System Compatibility — suitable for industrial single or three-phase distribution
- 3-Phase, 4-Connection Design — supports phase A, B, C, and neutral/ground connections
- 45 mm Terminal Spacing — standardized pitch for Allen-Bradley 140M modular frame breakers
- Compact Form Factor — saves horizontal panel space versus traditional busbars
- Drop-In Accessory — integrates seamlessly with existing 140M-C-D control centers
Technical Specifications
This busbar is engineered for 3-phase, 4-wire (3P+N) or 3-phase, 3-wire (3P) power distribution. It mounts directly on the 140M-C and 140M-D frame without additional brackets or adapters. Copper construction with tin plating ensures corrosion resistance in humid or corrosive environments. The busbar requires no external cooling and operates across the full industrial temperature range.
Typical Applications
- Multi-circuit branch distribution in industrial control centers
- OEM panel integration for machinery and equipment
- Motor control stations with branch-mounted disconnects
- Process automation systems requiring reliable power splitting
- Retrofit installations upgrading existing 140M control cabinets
Compatibility & Replacements
The 140M-C-W454N is designed exclusively for Allen-Bradley 140M-C and 140M-D series circuit breakers. It is not compatible with legacy 140G or older frame designs. Direct OEM replacement part; no equivalent from competing manufacturers. If upgrading from older busbar designs, verify terminal spacing and mounting rail alignment before installation. For systems requiring higher amperage, consult Allen-Bradley 140M series documentation for upgraded busbar options.
