This bulletin contains instructions for installation, operation, and
maintenance of the S&C Type FVR series circuit breaker (200 kV BIL)
manufactured by Square D Company.
It is important to read and understand this bulletin completely before
performing the installation, operation, and maintenance steps provided.
Electrical equipment should be installed and serviced only by qualied
electrical personnel. Qualied personnel should establish procedures that
ensure the safety of personnel and equipment.
The Type FVR circuit breaker is designed for outdoor substation applications
and provides interrupting capability for medium voltage systems up to 38 kV.
Circuits in which these circuit breakers are placed are capable of
overvoltages. Complex medium voltage systems may require a detailed
overvoltage system analysis and the addition of overvoltage protection.
The 200 kV BIL, Type FVR circuit breaker has been designed with an
arc-resistant enclosure.
The differences between the 200 kV BIL circuit breaker and all other Type
FVR circuit breakers are as follows:
The 200 kV BIL circuit breaker enclosure is larger.
The 200 kV BIL circuit breaker uses two vacuum interrupters in series on
each pole.
The 200 kV BIL circuit breaker uses a rotating operating shaft instead of
a cross bar design.
The 200 kV BIL circuit breaker enclosure has four side vent housings as
compared to two on the 110 kV to 150 kV BIL.

NOTE: For more information on operating and maintaining the other Type
FVR circuit breakers (110 kV to 150 kV BIL), refer to S&C Instruction Sheet
767-500.

The following is an explanation and sample of the catalog numbering
