Fixing Details |
| All types have 3 fixing options, base mounting feet, busbar clamps and captive M5 nuts. |
| Mounting Feet: Each current transformer is supplied with 2 push in feet which can be fitted in any of 8 positions. This allows for a very versatile combination of fixing arrangements. |
| Busbar clamps: These can be supplied in place of the mounting feet at no extra cost and enable the transformer to be mounted directly to the busbars. |
| Captive Nuts: Base mounting is provided by 2 captice M5 nuts in the base of the transformer. This allows the transformer to be fixed to panels where rear access is available. Screw projection should be between 8.5 and 9mm. |
