SYSTEM SETUP
5
A description of the operation of the breaker control and status monitoring features is provided in chapter 4. Information to
program the settings is covered here. These features are provided for two or more breakers; a user can use only those
portions of the design relevant to a single breaker, which must be breaker 1.
The number of breaker control elements depends on the number of CT/VT modules specified with the N60. The following
settings are available for each breaker control element.
BREAKER 1 FUNCTION

breaker poles are operated either independently or simultaneously.
— Selects an operand that creates a programmable signal to operate an output relay to open breaker 1.
