Electromagnetic Compatibility and Why is it Important for Enclosures

[fa icon="calendar'] Sep 8, 2015 4:00:00 PM / by Rittal Enclosures posted in Rittal Enclosures

Electromagnetic compatibility (EMC) is the ability of an electrical appliance to operate satisfactorily in its electromagnetic environment without adversely affecting this environment—which may also contain other equipment. High packaging densities in electronic assemblies and ever-increasing signal processing speeds often cause faults in complex electronic equipment, measurement and control systems, data processing and transmission systems and communications technology. These are attributable to electromagnetic influences.

The 5 Steps for Safe Switchgear Installation within Enclosures

[fa icon="calendar'] Sep 4, 2015 11:00:00 AM / by Rittal Enclosures posted in Rittal Enclosures

When planning switchgear installations, it is wise to consider the protection of the installers as much as what’s installed. This protection requires tested and standardized structures and wise energy distribution.

What’s the Weather Like in Your Electronics Enclosure?

[fa icon="calendar'] Sep 1, 2015 2:00:00 PM / by Rittal Enclosures posted in Rittal Enclosures, Climate Control, Data Center Solutions

Climate control inside your electronics enclosures is key to the survivability of the electronics residing there. Temperature rise in enclosures can be caused by contact problems with live conductors or incorrect dimensioning of switchgear and conductors. Also, when operating a low-voltage switchgear assembly, short-circuit losses occur, leading to a temperature rise in the enclosure’s internal air and, connected with this, inferior heat dissipation via the surface of the installed components and assemblies. This can lead to component damage.

Why Standards Are Important to an Enclosure’s Value

[fa icon="calendar'] Aug 27, 2015 2:00:52 PM / by Rittal Enclosures posted in Rittal Enclosures

Many people associate product standards with safety, but standardization also has a lot to do with a product’s cost. Rittal created a market breakthrough with the idea of standardizing enclosures for electrical devices. By using models with set dimensions, produced cost-effectively in large batches, Rittal is able to offer price and delivery benefits.

Parlez-Vous “Climate Control ”?

Like just about any other category of industrial operating equipment, there’s a unique vocabulary associated with climate control, cabinet ventilation, and enclosure cooling and heating. Learning to speak that language fluently can help you communicate effectively with system designers and contractors, and prevent time-wasting confusion. Here are some of the most commonly used terms you need to know:

Is Your Electronic Enclosure Running a Fever?

[fa icon="calendar'] Apr 27, 2015 11:34:00 AM / by Rittal Enclosures posted in Rittal Enclosures


Electronics enclosures are typically stuffed with electrical gear that generates heat as a by-product of operation, so controlling the temperature within them always involves a careful evaluation of their specific heating and cooling requirements.

When a low-voltage switchgear assembly operates, short-circuit losses can occur, which causes the temperature of the air inside the enclosure to rise. This, in turn, leads to poor heat dissipation from the surfaces of the installed components and assemblies, which can result in costly damage. Hot spots (over-temperatures that occur in isolated locations without natural air movement to dissipate heat) can be particularly troublesome.

Here are some common causes of rising temperatures within enclosures:

  • The operating equipment is too densely packed, obstructing airflow, or the components and conductors are incorrectly dimensioned.
  • Poor contact between individual live conductors.
  • Particularly in power distributors with high currents, the problem may lie in the formation of eddy currents in the assembly components and metallic surfaces adjacent to the conductors. As illustrated in the following diagram, current-carrying conductors that are inserted from beneath the enclosure through the gland plate can generate a magnetic field in the plate. Heat can be generated as a result of the eddy currents produced by this magnetic field.
