Question

How do I get my disconnect switch to close? I rotate the knob on my disconnect switch, but the main contacts do not close.

Answer

The SIRCO and Fuserbloc Series disconnect switches capable of three positions, ONLY when combined with a handle allowing the TEST feature. If the TEST feature is purchased, the disconnect switch has three positions/functions for the actuator as follows:

• T = Test - Only the auxiliary contact are closed (use for control circuit testing)
  
• 0 = Off - Both the auxiliary and main contacts are open
  
• 1 = On - Both the auxiliary and main contacts are closed

The sight window indicates the positioning of the actuator.

• From 0 to T is by CCW Rotation of the Actuator
  
• From 0 to 1 is by CW Rotation of the Actuator

Note: The force required for CW rotation is somewhat high. It may feel like the lever may break off, but keep turning until the "1" position indicator appears in the sight window. The Socomec Instruction Sheets may help
