Nameplate Content - Explained
Type
Designates circuit breaker model number and broadly identifies application in terms
of maximum voltage and interruption capabilities
Amps
amperes
Rated continuous current is the designated limit of current in RMS at rated
frequency, which the breaker may be expected to carry without exceeding
temperature limitations.
Rated Max Volts kV
The highest RMS voltage above nominal system voltage for, which the circuit
breaker is designed, and is the upper limit for operation.
Volt Range Factor(k)
The ratio of rated maximum voltage to the lower limit of the range of operating
voltage in which the required symmetrical and asymmetrical interrupting capabilities
vary in inverse proportion to operating voltage.
BIL kV
The rated full wave impulse withstand voltage. The crest value of a standard 1.2 x 50
impulse voltage wave which a new circuit breaker must be capable of withstanding
without flashover or puncture during design tests.
Rated Short kA
The symmetrical component of short-circuit current in RMS Circuit amperes, which
the breaker may be expected to interrupt
Close & Latch kA
The maximum making current into which the circuit breaker may be expected to close
and latch.
Inter Time Cycle
The maximum permissible interval between energizing the trip Circuit at rated
control voltage and the interruption of the main circuit in all poles.
Hz
Rated frequency is the sinusoidal periodicity at which the circuit breaker is designed
to operate.
Wiring Diagram
An elementary diagram providing detailed information regarding electrical function
and wiring within the circuit breaker.
Motor (Spring Charging)
Volt Range
Range of control voltages required to serve the motor which stores energy in the
closing springs.
Amps Nominal (Motor)
Effective value of current required at nominal control voltage when applied to serve
the motor, which stores energy in the closing springs.
Close(Solenoid) Volt Range Required range of control voltage applied to the closing solenoid which will insure
successful release of the closing spring and Citadel mechanism.
Amps Nominal (Close Coil) The effective value of current required at nominal control voltage when applied to
the close spring release solenoid.
Trip (Solenoid) Volt Range Required range of control voltage applied to the tripping Volt (opening) solenoid,
which will ensure a successful Range tripping (opening) solenoid.
Amps Nominal (Trip Coil)
The effective value of current required at nominal control voltage when applied to
the trip spring release solenoid.
Manual Reference to the instruction manual applicable to the circuit breaker by publication number.
LBS
Weight in pounds of the complete circuit breaker element.
Serial No
Specifically identifies an individual breaker and affords trace ability to test records
and manufacturing dates.
Date Mfg.
The month and year within which the circuit breaker was manufactured.
