Hager S941K Busbar Insulation Profile 20x10mm x 1000mm Grey

In electrical distribution boards and control panels, busbars carry high currents and need reliable insulation to prevent short circuits and accidental contact. The Hager S941K busbar insulation profile provides that protection. It is a grey PVC profile measuring 20 x 10 mm in cross-section and 1000 mm in length, designed to slide or snap over busbars made of copper or aluminum. Electricians and panel builders use it to insulate live busbar sections, improving safety and reducing the risk of flashover in indoor installations.

Key specifications

• Product type: Busbar insulation profile
• Material: PVC (Polyvinyl Chloride)
• Cross-section: 20 mm (W) x 10 mm (H)
• Length: 1000 mm

Why choose it

The S941K is made from self-extinguishing PVC, which means it will not propagate fire if exposed to a flame. Its snap-on design allows quick installation without tools, saving time during panel assembly. The profile is compatible with both copper and aluminum busbars, making it versatile for different busbar systems. Its grey colour blends with standard electrical enclosures.

Ideal use cases

• Insulating busbars in low-voltage distribution boards
• Protecting against accidental contact in control panels
• Retrofitting existing busbar systems to improve safety
• Separating adjacent busbars to prevent short circuits

Good to know

The profile is intended for indoor use and is not specifically UV resistant, so it should not be installed in direct sunlight. It is not halogen-free, which may be a consideration in projects requiring low-smoke, zero-halogen materials. The operating temperature range is -5°C to +60°C, suitable for most indoor electrical environments.
