About This Item
C37.16-2009 is a technical standard for voltage AC power circuit breakers rated 635 V and below, and DC power circuit breakers rated 3200 V and below. It addresses design and performance expectations for equipment used in power, energy, and industrial applications, where dependable interruption and control of electrical circuits are essential. As a superseded standard, C37.16-2009 remains useful for identifying legacy requirements and comparing older breaker specifications against project, maintenance, or procurement needs.
What is C37.16-2009?
C37.16-2009 defines requirements for low-voltage AC and higher-voltage DC power circuit breakers within its stated ratings. The document is relevant to breaker construction, electrical characteristics, and the conditions under which the equipment is expected to operate and interrupt current. In practice, it helps engineers, specifiers, and buyers understand the technical baseline for breaker selection and evaluation. For organizations working with legacy systems, C37.16-2009 can also serve as a reference point for documentation and comparison.
Where is C37.16-2009 used?
This standard is typically used in electrical power distribution equipment, industrial control installations, and other systems that rely on power circuit breakers within the specified AC and DC voltage ranges. It is especially relevant where switchgear, feeders, or protective devices must be coordinated for controlled interruption and reliable operation. C37.16-2009 may also be consulted during replacement planning, equipment specification, or review of existing breaker assets in energy and industrial facilities.
Why is C37.16-2009 important?
C37.16-2009 matters because breaker standards influence safety, consistency, and technical compatibility across electrical equipment. Clear requirements support more reliable procurement and help reduce the risk of mismatched ratings or unsuitable device selection. For design and maintenance teams, the standard provides a structured reference for evaluating performance and compliance in systems using AC or DC power circuit breakers. Since it is superseded, it is particularly valuable when dealing with legacy documentation or installed equipment.
