10.1.4 Disconnecting the Making and Breaking Units
• Remove the cotter pins (10) and flanged coupling pins (9) from
the two guide levers. We recommend tool T101 for removing the
cotter pins.
• Pull the interrupter unit out of the movable contact system.
10.1.5 Reconditioning the Movable Contact System
• Replace the arcing contact pin (29). Lubricate the contact
surfaces per lubrication specification L6. Tighten the screw (30) to
a torque of 25Nm.
• Replace the guide strip (11). The guide strip is located in a
dovetail groove. It is therefore necessary to overcome
mechanical resistance when replacing it.
• Lubricate the outer diameter of the movable contact system in the
area of the electrical sliding contact surface per lubrication
specification L6.
