Weatherproof Outdoor Electrical Enclosures

Most outdoor traffic enclosures use aluminum, typically 5052-H32 grade or 0.125-inch thick traffic-grade aluminum, for its durability, corrosion resistance, and lightweight properties. This construction protects sensitive equipment such as traffic signal controllers, detection modules, and battery backup systems from moisture, dust, and UV exposure.

Yes, enclosures in this category meet NEMA TS1, TS2-1, and TS2-2 standards, and many are compliant with the ATC 5301 V02 Advanced Transportation Controller Cabinet Standard. Several models also meet Caltrans, NYDOT, and FHWA specifications for state and municipal transportation projects.

Yes, specialized enclosures like the SE48-1616 and Alpha ITS power solutions are engineered specifically to house UPS modules, batteries, and transfer switches. They include features like sun shields, thermostat-controlled fans, and battery heating mats to maintain reliable backup power during outages.

Depending on the model, enclosures carry UL Listed, UL 508-approved, ISO Certified, and IPC Certified designations. Several are Type 3R rated for outdoor protection, and manufacturers like Econolite and Alpha are affiliated with IMSA for adherence to municipal signal industry standards.

Enclosures support various mounting configurations including pole-mount, pad-mount, and base-mounted rack designs, depending on the model. Battery backup enclosures like the SE48-1616 offer flexible pole-mounting for space-constrained intersections, while larger cabinets use base-mounted EIA 19-inch rack systems.

Enclosures use large sun shields to reduce solar heat load, thermostat-controlled fans and louvered vents for airflow, and optional battery heating mats for cold climates. Programmable temperature-compensated battery chargers also adjust charging rates based on ambient conditions to protect equipment reliability year-round.
