The Manual Shutoff Switch is a factory installed option that is available at the time of order for QCC models. The emergency stop, push button switch allows a person to manually control equipment in the event of an emergency. It is ideal for applications that require emergency electrical shutdown or ventilation purge. When combined with the Top Mounted Strobe, the device meets B52 code requirements for refrigeration applications.
 
The mechanism comes with one NC (normally closed) switch block. Normally closed is the reset / ready position.
 
NOTE: The metal guard will not fit over a QCC that has a Manual Shutoff Switch installed.
