333 Traffic Signal Controller Cabinet
When it comes to traffic management systems, particularly in areas poised for growth, the 333 traffic signal controller cabinet by Bison ProFab offers a reliable and scalable solution. Designed as a communications hub cabinet, this enclosure is perfect for municipalities and businesses ready to upgrade or expand their traffic control infrastructure.
The 333 Caltrans enclosure shares the same “footprint” as the widely used NEMA “P” cabinet, meaning it can be easily installed on existing concrete pads. This feature makes it an excellent choice for locations that require additional space for new control equipment, cabling, or other essential assemblies.
Purpose-Built for Expanding Traffic Systems
Bison ProFab built the 333 Caltrans enclosure with careful attention to structural integrity and operational practicality. Every element reflects a commitment to supporting complex traffic systems with ease of access, superior protection, and system longevity.
Before listing the technical features, it's important to highlight why they matter: maintaining uptime, protecting investments, and allowing personnel to service equipment quickly and safely.
Standard features include:
- Strong aluminum construction for corrosion resistance and structural durability
- Multiple access doors for efficient internal equipment management
- Integrated fan panel assemblies for optimized airflow and internal climate control
- Fluorescent lighting to assist maintenance crews during inspections or repairs
- Corbin #2 locks and keys to safeguard critical equipment against unauthorized access
- Transient voltage surge suppression for enhanced electrical protection
- Pad-mount configuration for stability and straightforward installation
Each feature is designed not merely for protection, but for long-term system resilience—an essential quality for high-traffic or growth-sensitive areas.
