Ex broadcast equipment “pulls”
I have been unable to identify the manufacturer but suspect they may be Cliff (UK) product

UNIDENTIFIED MANUFACTURER – IEC Panel Mount Socket
Fuse holder (M205) is isolated, meaning it can be rotated 180 degrees to make with a separate contact set. Why is this useful? For equipment which is dual voltage AC input, fuse in one direction is for 240V working and turn the fuse holder around and it is ready to go with 115V for example.
The front of the fuse holder actually indicates these two voltages
NOEMI Filter built in
Impressed into the rear of the socket (Standards)
AZ31 BS4491
Spade terminals to the rear of the socket (Active-Neutral-Earth plus Fuse a, Fuse b1 & Fuse b2 terminals and there are NO interconnections at the fuse holder b1 & b2)
Through hole, screw panel mounting (countersunk holes are 34.75mm apart, centre to centre)
Incorporates rotating fuse holder (2x fuses remain in place, change these to suit your application)
NO boot nor plug clip-lok, I have these available as separate items

DIMENSIONS:
Front: 28mm Wide x 31.5mm Height with side flanges (for the mounting holes) extending the width to 43.8mm
Depth: 17mm (excluding the spade/solder terminals)

COSMETIC CONDITION:
NEW Old Stock
Very good condition – no damage at all
Clean body, bright shiny nickel plated spade contacts which are relatively cleaned of previous solder, probably need further cleanup if it was intended to use spades with these terminals
Stored and supplied in sealed plastic
