Abstract

- Superseded. This standard pertains to direct-acting overcurrent, reverse-current, and undervoltage trip devices of both the electromechanical and ac solid-state types integral with low-voltage ac and general-purpose dc power circuit breakers covered by American National Standards. The solid-state direct-acting overcurrent trip devices may include ground trip elements. These direct-acting trip devices are sometimes referred to as "opening releases," especially in IEC (International Electrotechnical Commission) Recommendations or "Specifications."
