Doing the work of three – A unique way to use three-pole circuit breakers
It’s not a totally new idea: In order to save space and reduce cost, a three-pole circuit breaker can protect three single phase loads. What if the loads – e.g. electric motors – have different technical data and need different types of protection?
Differences and Similarities Between K Curve and D Curve Breakers
A Miniature Circuit Breaker (MCB) is a resettable protective device that prevents electrical circuits from catching fire and causing damage to personnel and property. It is a device designed to isolate a circuit during an overcurrent event without using a fusible element. There are two types of overcurrent events; a thermal overload and a short circuit.
Enhanced Short Circuit Protection for SCADA/RTU Systems with Remote Reset Capabilities
Process automation projects are most often driven by bottom line results, return on investment and an appropriate value position or justification. More and more, systems are expected to: provide access to quantitative measurement points of important processes, detect and correct problems immediately, measure trends, pinpoint and eliminate bottlenecks, control larger and more complex processes within a large geographic area...
Utilizing Class I Div. 2 Circuit Breakers in Liquid Natural Gas Applications
An increase in the demand for energy worldwide has driven the search for alternative primary sources of energy, even to the most remote locations of the globe. Natural gas, one of the leading alternative energy choices for fueling industries today, is considered the cleanest burning fossil fuel with minimal environmental impact. This white paper shares a real world example of how the integration of electronic circuit protection eliminates the need for widely used NEMA 7 enclosures and/or purge system and optimizes the LNG treatment process...
Dirty Dozen: 12 Most Common Mistakes When Specifying Circuit Protection for Equipment
It's only a circuit breaker. Yet there is enough complexity and confusion when it comes to specifying circuit protection that many engineers are designing equipment with too little or too much protection. Under protected circuits leave equipment vulnerable to damaging electrical surges. Over protected circuits add cost and can lead to nuisance tripping. Like Goldilocks and the three bears, the goal is to specify circuit protection that is "just right".
Improve Plant Production by Addressing 24VDC Switch-Mode Power Supply Issues
For most industries, the accepted norm for unplanned downtime is 5% of operating time, which represents a direct, significant loss of revenue and therefore profit. But have you ever stopped to consider the true cost of downtime? Read the latest white paper from E-T-A to see how the integration of electronic circuit control technology can reduce the downtime of your 24VDC system designs...
Overload or Short Circuit Protection? How to Protect Your Design Against Both Dangers
Circuit breakers are used in a variety of ways. They are mounted in panelboards to protect branch circuit wiring, and they are built into equipment to protect it. With this range of applications, it's not surprising that a circuit breaker must provide both short circuits and overload protection. This white paper will give pointers on how to determine the main job a breaker must do and how to make an appropriate selection...
