Screw-Type DIN Rail Terminal

DIN Rail Terminal: The Heart of Safe Connections in Industrial Panels ⚡️

In the world of industrial electricity, the DIN rail terminal (Rail Terminal Block) is a small yet extremely important component in electrical panels and accessories. At first glance, it may seem simple, but this small piece plays a crucial role in safe, organized, and reliable wiring connections.

Dena Electric Iranian screw-type DIN rail terminals are produced and offered in sizes 1.5, 2.5, 4, 6, and 10 mm².

Using standard, high-quality DIN rail terminals not only enhances electrical safety but also significantly simplifies troubleshooting and maintenance of electrical panels. With these terminals, panel wiring becomes more organized, cleaner, and more professional, reducing installation time and increasing operational efficiency.

If you are looking for a reliable solution for durable and robust electrical connections, selecting the right DIN rail terminal can make a significant difference in the safety and performance of your industrial electrical system.

Key Features and Advantages of DIN Rail Terminals in Industrial Panels ⚡️

High Current Capacity
Designed to handle instantaneous and heavy currents in industrial loads, making them ideal for motors, transformers, and other high-startup-current equipment.

Durable Body Material (Polyamide)
Constructed from heat-, flame-, and impact-resistant polyamide, ensuring stable performance and high safety even in demanding industrial environments.

Easy DIN Rail Installation
These terminals mount easily on DIN rails without special tools or complex procedures, saving installation time and speeding up industrial projects.

High Safety and Reduced Risk of Short Circuits
Standardized design ensures secure connections, minimizing the risk of accidental contact or short circuits.

High Rated Voltage
Typically rated up to 800V, suitable for medium-voltage industrial systems, offering flexibility in panel design.

Advantages of Using DIN Rail Terminals

Professional Wiring Organization: Keeps wires neat and organized, giving panels a clean, professional appearance.

Enhanced Electrical Safety: Prevents unsafe contacts and accidental connections, improving operator and equipment safety.

Easy Maintenance: Allows quick inspection and disconnection of wiring paths, reducing downtime during troubleshooting.

Cost-Effective and Durable: Long service life, resistance to harsh industrial conditions, and low maintenance costs.

Compliant with Global Standards: Designed according to IEC and UL standards for worldwide industrial applications.

Selecting the Right DIN Rail Terminal Size

Choosing the correct size of DIN rail terminal is critical for safety, performance, and the longevity of industrial equipment. Incorrect sizing can lead to overheating, unsafe connections, or panel damage.

Factors to consider:

Wire Cross-Section: Terminal size must match the wire diameter for a secure connection.

1.5 mm² wire → Size 1.5 terminal

4–10 mm² wire → Size for heavier loads like motors and transformers

Current Rating: Terminals must handle the nominal and peak currents of the circuit. Underrated terminals can cause overheating or equipment damage.

System Voltage: Terminal voltage rating should exceed the operating voltage to avoid insulation failure. For example, terminals rated up to 800V are suitable for most medium-voltage panels.

Environmental Conditions: In high-temperature, humid, or high-vibration industrial environments, heat- and impact-resistant polyamide terminals ensure long life, stable performance, and safety.

Correct sizing ensures safe, stable, and optimal performance, minimizing risks due to weak connections or overheating.
