Frequently Asked Questions

What class of insulating matting do I need?

The correct class depends on the maximum working voltage of your electrical installation.

Class 0 (1 kV) – LV panels, workshops, electrical maintenance areas.
Class 2 (17 kV) – MV switchgear, substations, utilities.
Class 4 (36 kV) – HV substations, power generation, transmission environments.

If you’re unsure, our engineers can help with class selection and compliance.

What’s the difference between Class 0, 2, and 4 insulating mats?

The classes define the electrical protection level, thickness, and test voltage according to BS EN 61111:2009.

Higher classes offer increased dielectric strength and are manufactured thicker to withstand higher voltages.
Class 0 → 3 mm
Class 2 → 4 mm
Class 4 → 5 mm

Each class undergoes rigorous proof and dielectric testing to ensure operator safety.

Can BS EN 61111 insulating mats be used outdoors?

Yes — EPDM rubber insulating mats such as COBAswitch™ are suitable for indoor and outdoor use. EPDM offers excellent resistance to:

Moisture and humidity
UV exposure
Ozone
Low temperatures

This makes them ideal for outdoor switchgear, substations, and exposed LV/HV environments.

Are BS EN 61111 insulating mats tested and certified?

Yes. Each mat is fully tested in accordance with BS EN 61111:2009 including:

Dielectric tests
Proof voltage tests
Thickness verification
Marking and batch identification
