A lockable disconnector has a mechanism that can retain the isolation position under a specified locking arrangement.

## What it represents

A lockable disconnector has a mechanism that can retain the isolation position under a specified locking arrangement. The representation needs the operating position and lock reference in addition to the main contact.

## How to read it

- A drawn padlock marker does not define the full isolation procedure.
- The preview is an original explanation of this function. Match the actual drawing convention to its legend and the selected equipment documentation.

## Information to show or reference

- Show lockable position
- Identify lock mechanism
- Cross-reference interlock schedule

## Important distinction

Lockability describes the mechanism; load-breaking capability describes electrical duty.

## Facts
