Powerbox Sig 17 released

There are now well over 1,000 Powerboxes installed on Network Rail's UK rail network and we were delighted to be able to demonstrate our latest model to them last week - the Sig 17. The Sig 17 is considerably larger than normal powerboxes as it has been designed to enable it to take cables up to 300mm. In addition, the cross members are removable improving access to the terminals.
