Using wiring kits for reversing contactor assemblies has the following advantages:

• Notable reduction of wiring in the control circuit
• Integrated mechanical interlocking for sizes S00 and S0
• Prevention of wiring errors in the main circuit

Connecting combs for screw terminals also result in:

• Prevention of wiring errors in the control circuit
• Reduction of testing costs
• Ready-jumpered actuation of the auxiliary switches and the frame (A2)
• Integrated electrical interlocking
