DIN Rail Enclosures

DIN rail enclosures are designed to internally mount complex circuit controls on custom-cut Polycase DIN rail kits. The kits can be mounted horizontally or vertically within the base of the 35mm DIN rail enclosure. Meeting several NEMA and IP ratings, our electrical enclosures with DIN rail are suitable for use in harsh environments. Made from durable polycarbonate or ABS plastic, DIN rail enclosures are available in a range of sizes to accommodate electrical or electronic applications.

DIN rails offer a simple and standardized way to mount various components and modules inside an electrical enclosure. These metal rails can accommodate a huge variety of electrical equipment — from power supplies to terminal blocks to automation controllers and beyond. In fact, many electrical components are designed for plug-and-play compatibility with the standard 35mm “top hat” DIN rail. 

DIN Rail Enclosures from Polycase

Our DIN rail mount enclosures are set up for quick and easy DIN rail mounting, with built-in PCB mounting bosses designed for compatibility with our DIN rail kits. Each DIN rail kit is a complete solution with all of the installation hardware you need. The slotted steel DIN rail is designed to fit your specific enclosure model perfectly, with no need for additional cuts, machining or adapters. Many kits offer multiple configuration options, depending on whether you want to install your DIN rail horizontally or vertically. 

These rugged plastic enclosures are designed with toughness and functionality in mind, and their NEMA and IP ratings offer outdoor-grade protection from water and dust ingress. In addition, our DIN rail enclosures are available in a variety of configurations, including wall-mounted enclosures and models with transparent covers. 

Finally, be sure to explore our powerful customization options. Need CNC machined cutouts to accommodate cable connectors or other equipment? Digital printing to add branding elements or safety requirements? Our in-house customization services offer robust options for both, with responsive customer support to help guide you through the process.
