Hubbell-Wiegmann| History of World Class Electrical Enclosures

The early 20th Century was full of technological advances and great historical moments. In 1928, Charles Lindbergh and Amelia Earhart were in the news for their famous feats of flying. The first television broadcasts began to appear on tiny black and white screens. Mickey Mouse was making movies – with sound. And, sliced bread made…

Thermal Management: Enclosure Cooling Tips

You need to cool down – Heat inside an enclosure can decrease the life expectancy of controlling units such as your PLC, HMI, AC drives and other items. Excessive heat can cause nuisance faults from your electrical and electronic components: for example, overloads tripping unexpectedly. Heat will also change the expected performance of circuit breakers and fuses, which can cause whole…

Selecting an Enclosure Fan or Air Conditioner

Internal and External sources often cause enclosure internal temperatures to rise above the ratings of the control equipment. Internally, the same items that can be damaged by heat (power supplies, PLC systems, AC drives/inverters, HMI systems, battery back-up systems, servos, etc.)  may also be the source of the heat. Externally, sources of heat that can

Selecting an Enclosure Heat Exchanger

Heat inside an enclosure can decrease the life expectancy of controlling units such as your PLC, HMI, AC drives and other items. Excessive heat can cause nuisance faults from your electrical and electronic components. Heat will also change the expected performance of circuit breakers and fuses, which can cause whole systems to shut down unexpectedly.

What to Know When Selecting an Enclosure

NEMA enclosures house all kinds of electrical components from simple terminal blocks, to industrial automation systems, to high voltage switchgear. In industrial automation systems, NEMA enclosures often house motor controls, drives, PLC/PC control systems, pushbuttons, and termination systems. Some enclosures are shaped to be operator consoles. AutomationDirect offers over 2,200 enclosure part numbers across NEMA…

Small-Scale Hydroelectric Plant Promises Profit

If there’s access to a stream, the only requirements to generate electricity are a 2 ft. drop in water level and two gallons of flow per minute. A hydroelectric system isn’t overly complicated, it isn’t difficult to operate and maintain, it has longevity and it’s often more cost-effective than other forms of renewable power. Some…

Enclosure Cooling Explained

What causes all that heat?  There are basically two sources of heat which cause an electrical enclosure’s internal temperature to rise above the manufacturer’s recommended ratings for the control equipment: internal and external sources. Internal Sources The same items which can be damaged by heat may also be a key source of the heat. These…
