IEEE approves revisions to one standard, begins work on four more

Jan 17, 2003 12:00 PM

IEEE’s standards board recently approved revisions to an existing circuit breaker standard and gave the green light to work on further revisions to four more circuit breaker and surge protection standards.

IEEE C37.14, “Standard for Low-Voltage DC Power Circuit Breakers Used in Enclosures,” incorporates 1,000V and 1,200V maximum voltage ratings. It was updated to reflect comments received on peak current design testing and to adapt it to the metric system.

The four other standards that IEEE will begin revising are:

• IEEE PC37.13, “Standard for Low-Voltage AC Power Circuit Breakers Used in Enclosures”

• IEEE PC37.27, “Application Guide for Low-Voltage AC Nonintegrally Fused Power Circuit Breakers (Using Separately Mounted Current-Limiting Fuses)”

• IEEE PC62.31, “Standard Test Specification for Gas-Tube Surge Protection Devices”

• IEEE PC62.64, “Standard Specification for Surge Protectors Used in Data Communications and Signaling Circuits”

Dates for the completion of the revisions haven’t been announced.
