Each low voltage power circuit breaker shall be supplied with a

breaker-mounted microprocessor device with 3-phase and

neutral protection, metering and communications capabilities.

The device shall comply with the requirements of ANSI C37.17.

Standard trip functions shall include Long Time (LT), Short

Time (ST), Instantaneous (INST) and Ground (GRND) current

protection.

: The trip unit will be suitable for 3-phase

YSTEM

PPLICATION

systems, with or without a neutral connection, and voltages

between 208 and 600 VAC

RMS

be suitable for continuous currents up to 4200 amps, ground

currents up to 1200 amps, and short circuit currents up to

130kA.

: Tripping functions shall be self-powered, requiring no

OWER

auxiliary power source. Trip system memory shall be non-volatile

and shall not require battery back-up or other control power to

retain stored information. A battery or other power source must

be provided for metering, interrogation and to change settings

when the breaker is not energized. The battery must be a

common "off the shelf " device.

: The trip device shall operate in an ambient

NVIRONMENT

temperature range from -20

1) employ active and passive filtering techniques, 2) be

impervious to and not have false operation due to EMI or RFI

from any source as demonstrated by satisfactory testing in

accordance with ANSI standards C37.90.1 and C37.90.2,

respectively.

: The device shall include the ability to view protection

by direct connections to the three phases of the circuit breaker

being interrogated in order to retain the correct time

relationships for power calculations. Circuit breaker-mounted

potential transformers (PT's) shall condition the voltage signal

for use by the trip system voltage interfaces.
