LERDN believe that service shouldn't end after you've purchased our products and that, if you've chosen us, we should continue to support you. Whether you require a quote, product information or after sales advice our team is ready to help you.

Unlike some vendors, we don't simply supply surge protection, we design and manufacture it. Because of this our technical support engineers have the luxury of knowing their products inside out and won't simply be quoting from a support manual.

We are constantly developing new products to serve the diverse range of applications where surge protection is required. If we do not currently have a product that meets your needs, please contact our design team who will be happy to discuss the development of a new or custom product to your specification

LERDN can be contacted by email spd@lerdn.com or you can contact your local LERDN reprsentative. You can find the details of you local representative in the distribution section of this site.
