Automatic changeover switch

for generator sets

Network – generator systems can be made with compact type circuit breakers with motor mechanism or combination of compact type circuit breaker and contactor either.As seen on right diagram, compact type circuit breakers are used for overload and short circuit protection while contactors are used for switching. Changeover system can be made with mechanical and also electrical locking for contactors up to FC95D and with electrical locking only for contactors FC115D to FC750D Changeover system 300A to 2500A can be made with mechanical and also electrical locking by using high current contactors.
