FOREWORD
This booklet provides information for the Medium Voltage (5kV to 27kV) AMVACTM indoor circuit breakers as described
below. Note: not all sections of this bulletin appllies to all the types of AMVACTM circuit breakers. For example, the
racking and interlock sections only apply to the draw-out (removable) versions and do not apply to the fixed-mount
breaker styles. Also sections on the ED2 board contains all options available on the board but may not be utilized de-
pending upon options ordered. All information in this booklet was current at the time of printing. All references in this
booklet are determined from viewing the circuit breaker from the front.
DRAWOUT (REMOVEABLE):
A drawout circuit breaker is a breaker that may be removed from a cell without the unbolting of any connections or
mounting supports. It utilizes specific interlock devices that function according to ANSI standards, which allow for the
safe removal of the device with minimal risk to personnel. It is intended for use in SafeGear®, ADVANCETM, or
abbreviated versions of ABB and OEM switchgear. It also contains plug-in primary and secondary disconnects with
three physical ANSI operating positions within the cell: Disconnect, Test, and Connected. In the disconnected position
there are no electrical connections. In the test position only, the secondary control wiring is connected via a patented
disconnect mechanism which allows for remote testing of the breaker operations. The connected position, both primary
and secondary circuits are connected and the breaker is ready for normal operation.
FIXED-MOUNT:
A Fixed-mount circuit breaker is intended to be mounted as a stationary device. It does not contain any racking related
interlocks and/or primary leads. Primary connections are hard bussed to the associated gear in which the breaker is
installed by the consumer. Secondary wiring is terminated on a 5 foot length of wire from the module to secondary
plugs that are the same as the draw-out versions. Plugs and associated pins can be purchased for plug in connection
or the wires may be cut to provide direct connections. The fixed mount version must be provided with the plugs in this
manner to meet UL listing and to insure proper testing of the breaker. The customer is responsible for any damage to
the breaker that is due to mis-wiring of the breaker.

SAFE PRACTICES:
AMVAC™ circuit breakers are equipped with high energy electrical storage capacitors. The design includes several
interlocks and safety features which help ensure safe and proper operating sequences. To ensure safety of
personnel associated with installation, operation, removal, and maintenance of these circuit breakers, the following
recommendations must be followed:
Only qualified persons, as defined in the National Electric Safety Code, who are familiar with the installation and
maintenance of medium voltage circuits and equipment should be permitted to work on these circuit breakers.
Read these instructions carefully before attempting any installation, operation, or maintenance of these power circuit
breakers.
DO NOT work on an energized circuit breaker.
DO NOT work on a circuit breaker unless all components are disconnected by means of a visible break and
securely grounded.
DO NOT work on a circuit breaker with power supplied to the secondary control circuit.
DO NOT defeat safety interlocks. This may result in bodily injury, death and/or equipment damage.
DO NOT work on a closed circuit breaker.
DO NOT work on a circuit breaker with charged energy (springs, capacitors, etc.).
DO NOT use a circuit breaker by itself as the sole means of isolating a medium or high voltage circuit.
DO NOT leave a circuit breaker in an intermediate position in a cell. Always place the circuit breaker in the
Disconnect, Test or Connect position without hesitation between positions.
THE CIRCUIT BREAKERS DESCRIBED IN THIS BOOK ARE DESIGNED AND TESTED TO OPERATE
WITHIN THEIR NAMEPLATED RATING. OPERATION OUTSIDE OF THESE RATINGS MAY CAUSE THE
EQUIPMENT TO FAIL, RESULTING IN PROPERTY DAMAGE, BODILY INJURY AND/OR DEATH.
ALL ANSI AND NEC SAFETY CODES, SAFETY STANDARDS AND/OR REGULATIONS AS THEY MAY BE
APPLIED TO THIS TYPE OF EQUIPMENT MUST BE ADHERED TO STRICTLY.
WARNING
INTRODUCTION:
The purpose of this manual is to provide instructions for unpacking, storage, installation, operation, and maintenance
for AMVAC™ vacuum circuit breakers. This manual should be carefully read and used as a guide during
installation, initial operation, and maintenance.
The specific ratings of each model circuit breaker are listed on the individual nameplates. The AMVAC™ circuit
breakers are protective devices. As such, they are maximum rated devices. Therefore under no circumstances
should they be applied outside of their nameplate ratings. Refer to ANSI and IEEE guidelines referring to the use of
circuit breaker applications.
NOTICE
FAILURE TO OBSERVE THE REQUIREMENTS OF OSHA STANDARD 1910.269 CAN CAUSE DEATH OR
SEVERE BURNS AND DISFIGUREMENT. THIS STANDARD SPECIFICALLY PROHIBITS THE WEARING OF
POLYESTER, ACETATE, NYLON, OR RAYON CLOTHING BY EMPLOYEES WORKING WITH EXPOSURE TO
ELECTRIC ARCS OR FLAMES.
