Disconnect Switch Selection
Disconnect Switch Selection
(OP)
Hi, I'm not sure if this is the right place to be posting this but I was wondering if someone could lay down some general guidelines to keep in mind when selecting a disconnect switch for a PLC panel.
For example, I have to select a disconnect switch for a Panel that has a MicroLogix 1200 PLC, a motor (12.4/9.5 A), and 4 heaters (220V 300W each).
Anything you can add would be a great help. Thanks.

External or panel mounted (interlocked?)
How often it will be actuated
Compliance with Lockout/Tagout
Enclosure type (suited for environment)
Susceptibility to damage (believe me, it will happen)

Chapter 5 covers disconnects.
