Circuit Breakers and Disconnecting Switches 1

3783

Description

The Circuit Breakers and Disconnecting Switches 1, Model 3783-0 can be operated independently using dedicated I/O (open/close) switches or open/close control inputs on the front panel. An Ethernet port on the module front panel allows all circuit breakers and disconnecting switches to be controlled independently using a SCADA system. Green (close) and red (open) pilot lights on the front panel indicate the state of each circuit breaker and disconnecting switch. Open/close auxiliary contact sets are provided for each of the 3 circuit breakers. Open/close auxiliary contact sets are provided for one of the disconnecting switch. Module operation requires 120 V dc power which is applied to the module via two safety banana jacks on the front panel. Electric power substations with the following switching schemes, i.e., the bus (busbar) arrangements, can be implemented using two Circuit Breakers and Disconnecting Switches modules (Models 3783-0 and 3783-A):

• Single Bus

• Double Bus, Single Breaker

• Main Bus with Transfer Bus

• Ring Bus

• Breaker-and-a-Half

• Double Bus, Double Breaker
