ECN Forum Forums General Topics of the Trade General Discussion Area interlocking disconnects

Can anyone spec a disonnect with door interlock that also breaks the load via a contactor? Supply is three phase, 208 volt up to 600 volt, 100 to 200 amps. I am looking at a device that will prevent unauthorized persons from using the disconnect to break the load , and prevent them from opening an energized disconnect. thanks.

Jay,
You can get field installed control circuit interlock switches for most disconnects. These interlock switches open before the main contacts of the disconnect and could be used to control a remote contactor.
