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.

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...

Save Energy by Reducing CO2 Emissions in Vehicles

The limit values for carbon dioxide emissions are getting stricter and stricter globally. By 2020 the average emission of new cars will drop to 95 g/km in the European Union. For light commercial vehicles the target value is 147 g/km. For passenger cars this corresponds to a consumption of 4.1 litres petrol or 3.6 litres diesel. These numbers are driving passenger car manufacturers to look for ways to further reduce fuel consumption and in turn carbon dioxide emissions.

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...

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?
