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 maximum rated 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."

C37.14-2015
IEEE Standard for DC (3200 V and below) Power Circuit Breakers Used in Enclosures
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.
These standards have been replaced with a revised version of the standard, or by a compilation of the original active standard and all its existing amendments, corrigenda, and errata.
C37.14-2002
IEEE Standard for Low-Voltage DC Power Circuit Breakers Used in Enclosures
Reaffirmed 2008. Revision of IEEE Std C37.14-1999. This IEEE Standards product is part of the C37 family on Switchgear, Substations and Protective Relays. Abstract:This standard covers enclosed low-voltage dc power circuit breakers of the stationary or draw-out type of one- or two-pole construction with one or more rated maximum voltages of 300 V, 325 V, 800 V, 1000 V, 1200 V, 1600 V, or 3200 V for applications on dc systems having nominal voltages of 250 V, 275 V, 750 V, 850 V, 1000 V, 1500 V, or 3000 V, with general-purpose, high-speed, semi-high-speed and rectifier circuit breakers; manually or power-operated; and with or without electromechanical or electronic trip devices. It deals with service conditions, ratings, functional components, temperature limitations and classification of insulating materials, dielectric withstand voltage requirements, test procedures, and application.
