Havells, the specialist in low voltage switchgear, together with Furse, designer, manufacturer and supplier of earthing and lightning protection systems, has launched a comprehensive surge protection solution designed to simplify selection and installation of Surge Protective Devices (SPDs) in accordance with the latest amendment of BS 7671.
Surge protection within the Havells Powersafe distribution board range has been optimised through testing with Furse; the combined solution achieves the lowest possible let-through voltage and removes many of the installation variables. Uniquely, the Havells/Furse solution provides a tested level of system performance that complies with the recent IET wiring regulation requirements for surge protection device installation.
Lightning protection for buildings is a complex subject, but selecting SPDs as part of an electrical distribution solution, needn't be. The objective in fitting SPDs is to protect against transient overvoltages, which degrade and damage electronic systems, leading to disruption, expensive downtime and fire/electric shock hazard.
Mike Lawrence, Marketing Manager at Havells explains: "In simple terms the challenge is to limit the overvoltage or surge most commonly caused by indirect lightning strikes, so that any downstream sensitive electronic equipment is protected. The issue with many installed SPD solutions is that although it will have some level of tested performance, once installed within the electrical distribution architecture, this may not relate to any real level of protection afforded to the building. The configuration of Furse SPDs within each assembly has been standardised to reduce installation variables to ensure that an SPD operates at optimum performance maintaining the integrity of the electrical system."
Havells Type 'A' SPN, Type 'B' TPN and MCCB distribution boards are available with Furse ESP mains power SPD kits and can be quickly and easily installed either in the metering section (MCCB boards) or in the enclosure provided (Type 'A' SPN or Type 'B' TPN boards).
This innovative solution has been specifically designed and tested to ensure optimum transient overvoltage protection on AC power supplies, with controlled and verified installation performance to BS 7671 and BS EN 62305. Installation is hassle-free as all components and instructions are provided within the SPD kit, enabling contractors to progress quickly throughout the site without worrying about the effectiveness of the installed protection, saving both time and cost.
Once installed, the SPD will provide reliable, long lasting transient overvoltage protection of the AC power supply, with the ability to withstand repeated transients and give clear pre end-of-life warning, allowing plenty of time for replacement, so as to ensure users are not left unprotected.
