For Release:
Immediate
PISCATAWAY,
N.J., 16 Jan 2003 The Institute of Electrical and Electronics
Engineers Standards Association (IEEE-SA) Standards Board has
approved a revised version of IEEE C37.14 ™, "Standard
for Low-Voltage DC Power Circuit Breakers Used in Enclosures."
It also approved the start of work on a performance and testing
standard for hardwired, multiport surge protectors used with low-voltage-line
equipment, as well as on revisions to four existing circuit breaker
and surge protection standards.
The approved
revised standard, IEEE C37.14, incorporates 1000V and 1200V maximum
design voltage ratings. It was updated to reflect comments received
on peak current design testing and to adapt it to the metric system.
The new standards
project, IEEE PC62.51 ™, "Standard for Performance Criteria
and Test Methods of Hardwired Multiport (Multiservice) Surge-Protective
Devices for Equipment Connected to 120/240 V Single Phase Power
Service and Communication Lines," concerns equipment connected
to one or more communications line and 120/240 V single-phase
ac power and having the neutral grounded at the service equipment.
This standard will help engineers, specifiers and test facilities
to design and evaluate surge protective devices.
The four standards
to be revised are:
· IEEE PC37.13 ™, "Standard for Low-Voltage AC
Power Circuit Breakers Used in Enclosures," guides users
in evaluating switching devices in low-voltage switchgear up to
1000V. It defines the type of replacement, outlines required interlocks,
suggests appropriate testing and creates a marking system to identify
devices as replacements.
· IEEE PC37.27 ™, "Application Guide for Low-Voltage
AC Nonintegrally Fused Power Circuit Breakers (Using Separately
Mounted Current-Limiting Fuses)," addresses enclose, low-voltage
ac power circuit breakers. It will be updated to reflect the use
of electronic trip devices on low-voltage breakers and converted
to the metric system.
· IEEE PC62.31 ™, "Standard Test Specification
for Gas-Tube Surge-Protective Devices," will be revised to
reflect comments received on it and to harmonize it with relevant
IEC and IEEE documents. The standard applies to gas-tube surge-protective
devices that limit voltage surges on balanced or unbalanced communication
circuits and power circuits operating from dc to 420 Hz on 1000
Vrms or 1200 Vdc systems.
· IEEE PC62.64 ™, "Standard Specification for
Surge Protectors Used in Data Communications and Signaling Circuits,"
will be updated by adding information on new technology and devices,
including a multiport SPD. This standard provides performance
parameters to help users specify and apply surge protectors in
data, signaling and communication devices.
These projects
are sponsored by the IEEE
Power Engineering Society.
About the
IEEE Standards Association
The IEEE Standards Association, a globally recognized standards-setting
body, develops consensus standards through an open process that
brings diverse parts of an industry together. These standards
set specifications and procedures to ensure that products and
services are fit for their purpose and perform as intended. The
IEEE-SA has a portfolio of more than 870 completed standards and
more than 400 standards in development. Over 15,000 IEEE members
worldwide belong to IEEE-SA and voluntarily participate in standards
activities. For further information on IEEE-SA see: http://standards.ieee.org/.
About the
IEEE
The IEEE has more than 375,000 members in approximately 150 countries.
Through its members, the organization is a leading authority on
areas ranging from aerospace, computers and telecommunications
to biomedicine, electric power and consumer electronics. The IEEE
produces nearly 30 percent of the world's literature in the electrical
and electronics engineering, computing and control technology
fields. This nonprofit organization also sponsors or cosponsors
more than 300 technical conferences each year. Additional information
