PMA, 20 mm Nominal Diameter, Plastic, Black

ABB Series LL Conduit, 20mm Nominal Diameter, 50m Length - LL-17A.50

This conduit is a flexible, light‑wall polypropylene tube designed to protect cables in automation, electronics and mechanical installations. Supplied in black on 50m rolls, it offers chemical resistance and ease of pre‑assembly for machine‑building and panelwork environments while remaining suitable for confined routing where tight bends are required.

Features & Benefits

• Rated for continuous use between -20°C and 90°C providing wide thermal tolerance
  Constructed from halogen‑free polypropylene offering chemical resistance
  Impact and flame resistant material improving mechanical and fire performance
  Minimum static bend radius 40mm enabling Compact installations
  Tested to EN 50086 and IEC 61386 supporting international conformity
  UL94 HB classification reduces flame propagation risk during incidents

**Applications**

• Suitable for cable protection in machine building and plant installations
  Ideal for routing control and signal cables in electrical panels
  Used with PMA Smart Line and PMAFIX accessory systems
  Can be used where chemical exposure to strong acids is a concern
  Suitable for pre‑assembled installations requiring flexible conduit runs

What roll length is supplied for large installations?

The product is delivered on 50m rolls to facilitate extended runs and reduce jointing.

How does the material behaviour affect installation speed?

The light‑wall polypropylene design allows easy handling and simple pre‑assembly, reducing fitting time compared with heavier conduits.

Is this suitable for hazardous area certification?

It is not certified for hazardous areas and should not be specified where hazardous‑area approval is required.

What mechanical tests support its durability?

Laboratory tests Record impact strength greater than 3 J and Peak load values exceeding 150 N for 50mm samples, demonstrating mechanical resilience.

Which standards govern its flame and physical properties?

Flame and density characteristics were assessed according to UL94 HB and DIN test methods respectively.
