Under Ground - Over Ground


Craig and Derricott are pleased to announce a further extension to their range of London Underground (LUL)/Transport for London (TFL) approved Switchgear. 


Registered for ‘surface’ & ‘sub-surface’ use, the range now includes both i-switch LUL hinged lid sheet steel Switch Disconnectors and Fuse Combination Units for the isolation/distribution of electrical supplies. 

The extended range of Switchgear, which has passed the stringent  LUL/TFL formal acceptance procedure, was officially approved on the 26th February 2015. 


Covering a range from 40A to 400A in Switch Disconnectors and 32A to 630A Fuse Combination Units, all units are lockable in the ‘Off’ position as standard with an option to include locking in the ‘On’ position. The switches can even be supplied with Castel Locks for additional Personal Protection and safe op­erating procedures. 

Authorised for primary use on surface and sub-surface applications, these items are fully approved to 1-085. The robust construction of this selection of  Switchgear is also IP65. 

The newly authorised switches have been included to complement the ex­isting LUL/TFL Approved Die Cast and Stainless Steel 25A and 40A Switch Disconnections.
