DIN Rail Channel Sizes

DIN Rail Channel Sizes

A DINRail Channel is a standardized metal rail used to mount circuit breakers, terminal blocks, relays, timers, and other control equipment inside electrical enclosures and distribution boards. DIN rails are manufactured in various sizes and shapes to accommodate different types of devices and loads. The most common profiles include Top-Hat (TH35), G-type, and C-type rails, each defined by their width, height, and flange shape. Sizes conform to IEC 60715 / DIN EN 50022 standards, ensuring global compatibility. DIN rail channels offer a modular, efficient, and reliable platform for organizing and supporting electrical components in a clean, professional manner.

Top 10 Frequently Asked Questions (FAQs) of DIN Rail Channel Sizes

What does DIN stand for in DIN Rail?
It stands for Deutsches Institut für Normung, the German standards organization.
What are the most commonly used DIN rail sizes?
The TH35 (35mm) rail is the most widely used for mounting modular electrical components.
How are DIN rail sizes standardized?
They are defined by IEC 60715 and DIN EN 50022 international standards.
Can all devices mount on the same DIN rail?
Most modern electrical devices are compatible with TH35 rails; others may require specific types.
What materials are DIN rails made of?
Usually galvanized steel, aluminum, or stainless steel for corrosion resistance.
Are DIN rails reusable and easy to cut?
Yes, they can be cut to size and reused if undamaged.
What’s the difference between TH35-7.5 and TH35-15?
Both are 35 mm wide, but the 15 version is deeper and supports heavier devices.
Do DIN rails provide grounding?
Some types (like C-rails) can serve as grounding rails if properly bonded.
Are DIN rails used only in electrical panels?
No, they’re also used in automation, telecom, railway, and building control systems.
Do DIN rail sizes affect mounting space in the enclosure?
Yes, larger rails (e.g., G32 or C40) require deeper enclosures for proper fit and clearance.
