is a world leader in the design,
manufacture and supply of earthing and
lightning protection systems.
A Havells / Furse
®
strategic alliance offers fully type tested
solutions of complete assemblies, including Type A/B
distribution boards and MCCB panel boards. This concept
is unique to the current selection of surge protection devices
within an electrical system as a proven level of energy let
through voltage can be confirmed for a complete assembly
and not simply sub components. (certificates can be found
in our technical section).
The configuration of surge protection devices within each
assembly has been standardised to reduce installation
variables to ensure that a surge protection devices operates
at optimum performance maintaining the integrity of the
electrical system.

SPD function
The lightning discharge or transient overvoltage is
impeded from reaching further into the structure and is
instead diverted safely to earth. In doing so, the SPD
prevents dangerous sparking through flashover and also
protects equipment.
