Revision Standard - Active. Enclosed dc power circuit breakers of the stationary or drawout 32 type of one- or two-pole construction with one or more rated maximum voltages of 300 V, 325 V, 33 600 V, 800 V, 1000 V, 1200 V, 1600 V, or 3200 V for applications on dc systems having nominal 34 voltages of 250 V, 275 V, 500 V, 750 V, 850 V, 1000 V, 1500 V, or 3000 V, with general-purpose, 35 high-speed, semi-high-speed and rectifier circuit breakers; manually or power-operated; and with 36 or without electromechanical or electronic trip devices are covered in this standard. Service conditions, ratings, 37 functional components, temperature limitations and classification of insulating materials, dielectric 38 withstand voltage requirements, test procedures, and application are dealt with in this standard.
This standard covers the following types, preferred ratings, and testing requirements of enclosed dc power circuit breakers: a) Stationary or drawout type of one- or two-pole functional construction b) Having rated maximum voltages of up to 3200 V c) Manually operated or power operated d) With or without overcurrent trip devices NOTE--In this standard, the use of the term "circuit breaker" is considered to mean "enclosed dc power circuit breaker."
The purpose of this document is to: a) Establish minimum functional requirements b) Establish preferred rating structure c) Provide preferred ratings d) Establish testing requirements
