PMA, 25 mm Nominal Diameter, Plastic, Grey

ABB Series LL Conduit, 25mm Nominal Diameter, Grey - LL-23S

This conduit is a flexible, light‑wall polypropylene conduit designed to protect electrical cabling in industrial and machine‑building environments. It offers chemical resistance and suitability for use where reduced weight and flexibility are required, while providing protection against ingress and hazardous‑area conditions.

Features & Benefits

• Operates across a −20°C to 90°C temperature range for varied environments
  Withstands repeated flexing for long service life under movement
  Acid‑resistant material reduces corrosion risk from aggressive media
  Compatible with M25 threaded fittings for secure terminations
  Low density yields easy handling and simplifies installation

**Applications**

• Suitable for cable routing in machine building and apparatus construction
  Ideal for flexible installations in automation systems requiring tight bends
  Used for protecting wiring in hazardous areas with explosion‑protection needs
  Can be used with modular conduit accessories and connector systems

What material properties enable chemical resistance?

The conduit is MADE from specially modified polypropylene with a density around 0.90–0.92 g/cm3, providing resistance to strong acids and a halogen‑free composition.

How does the product perform under mechanical stress?

Impact strength exceeds 3 J and Peak load values are greater than 150 N for 50mm samples and greater than 300 N for 100mm samples, while reversed bending endurance is over 100,000 cycles.

What mounting or assembly advantages does it offer?

The light‑wall construction allows pre‑assembly and straightforward installation with compatible connector systems, reducing handling time on site.

Which approvals and protection classes apply to its usage?

It meets EU and UL approvals and is certified for hazardous‑area installation with multiple ingress ratings to suit different environmental demands.

How should static installations be configured regarding bend radius?

The lowest recommended bending radius for fixed installation is 45mm to preserve conduit integrity and cable performance.
