Main Circuit -
Surge suppressor mod-
ules
The main circuit surge suppressors are available with the following rated
operational voltages:
• 500 V < Ue <= 690 V: 3RT1966-1PV3
• 690 V < Ue <= 1000 V: 3RT1966-1PV4
The surge suppressor is connected:
• with a 35 cm long, built-in cable separate from the contactor
• on the load side of the contactor 2-T1/4-T2/6-T3
