IEC/EN 61643-11 International Standard – Are your Surge Protective Devices (SPDs) tested and compliant?

From |

Surge Protective Devices Must Meet Standards

Surge protective devices (SPDs) must provide defined protective functions and performance parameters in order to be suitable for use in corresponding protection concepts. As such, they are developed, tested, and classified according to their own international series of product standards.
Surge protective devices connected to low-voltage power systems are subjected to the requirements and test methods specified by the latest IEC/EN 61643-11 International Standard.

A true mark of quality is a product certification and approval from an independent testing institute. This confirms the fulfillment of the latest state-of-art product standard to ensure highest safety and integrity of the SPDs. The regulatory requirements placed on SPDs often require highly complex tests that only a few testing laboratories in the world are fully capable of carrying out.

How do you know?

The quality and performance of surge protective devices are hard for a customer to assess. Correct functioning can only be tested in suitable laboratories. Besides the external appearance and haptics, only the technical data provided by the manufacturer can provide any guidance. Even more important is a reliable statement from the manufacturer & certification/approval regarding the performance of the SPD and the execution of the tests specified in the respective product standard from series IEC 61643.

Safe Energy Control SPD

Safe Energy Control (SEC) SPD

In line with the revision of the most recent IEC/EN 61643-11 International Standard, the latest range of Safe Energy Control (SEC) SPDs from Phoenix Contact is furnished with independent certifications (i.e. KEMA/DEKRA, DNV/GL, UL). The SEC protective devices work discreetly in the background, providing consistent safeguarding for the entire system even in cases where high lightning surge currents are being discharged.

CLIPSAFE – Your one-stop junction box solution

From |

The “Blame Game”

Have you ever been bothered by such a situation?  Picture this, you have just completed your run on a beautiful day only to return home and realize that your feet are full of blisters. Should you put the blame on the shoe manufacture for using a material that is too tough, or would you blame the socks company for using a material that is too soft?


Things can potentially get uglier when it comes to planning for or executing a project. Have you had the unfortunate experience of opening a ‘Brand X’ junction box, to find yourself having ‘Brand A’ terminal blocks and maybe some ‘Brand C’ cable glands or markings inside. If there is a fault, who you should go to?

You may potentially find yourself being trapped in the “Blame Game” if you are having two or more different suppliers involved.  And if you have ever been trapped in one, you will know that the chances of successfully finding a solution and getting out is very minuscule.

What if there was a supplier who could provide you with a one-stop shopping experience?

CLIPSAFE – Your one-stop junction box solution

Over the years, many of our customers have requested Phoenix Contact to provide one-stop services where they not only purchase standalone components but are able to purchase a solution. We realized it made perfect sense for us to develop a portfolio of “basket or box” which would allow us to further improve our customers’ buying experience. This was the genesis of our CLIPSAFE range of junction boxes.

Device connection for high currents

Device connection for high currents

Improve efficiency and productivity is a common mission all companies want to achieve.  A company with high efficiency can produce more results while maintain it’s overhead, thus increase its profit margin. Through a switch of screw to spring connection technology,  it is possible to achieve the desired result.

Let’s take a look at the connectivity trends, the demand for quick-connection technology is steadily growing. Today, the spring-cage-based connection technologies allow convenient conductor connections within seconds, and the defined contact force makes them safe as well. In addition, terminal failure due to improper torque can be avoided this way. Until now, there is no device connection with quick-connection technology for cross sections of more than 35 mm².

The panel feed-through terminal blocks TW 50 and TW 95 with the new T-LOX connection technology from Phoenix Contact, connectivity has been comes simple and convenient. It even can support multi-strand connectors still ensuring a flexible and safe connection. The T-LOX connection principle is based on a spring that generates a programmed contact force with just a conventional screwdriver.

TW 50 TW 95
Cable Cross-section 16 mm² – 50 mm² 25 mm² to 95 mm²
Current capacity Up to 150 A Up to 232 A
