VFD Disconnect Switches

ACI's Disconnect Switch for Variable Frequency Drives (VFDs) prevents downtime of equipment due to the VFD being damaged trough a "non-sequenced shutdown".
When a motor disconnect switch is turned off while the VFD is in operation, the result can damage critical electronic components such as transistors.  The contacts in the disconnect switch itself can be damaged! 

This damage can cause costly equipment repair and excessive process downtime as well as a potential safety risk to personnel.

ACI's line of Patented Disconnect Switches specifically for VFD applications protects them from inadvertent and non-sequenced shutdowns.

ACI integrates an 'early break auxiliary contact' into the disconnect switch which signals the VFD's processor that the disconnect contacts are being switched off.  This allows the VFD to start the proper shutdown sequence, thus sparing damage to the internal electronic components and to the disconnect switch.

The VFD Disconnect Switch Series is available as a ready to mount Enclosed Unit or as Open Components for mounting in your control panels.  Available in 30, 40, 60, and 80 amp sizes.
