Yes we can....with Phoenix
For machine and plant manufacturers who export their products to North America or wish to put them into circulation within the area of application, the laws and regulations applicable there apply. One of the most important industry-specific standards besides the NEC is NFPA 79. NFPA 79 is revised every three years, following the NEC, and adopts its innovations.
Find out what requirements electrical equipment must meet under NFPA 79 for the use of surge protection modules (SPDs). Play it safe with us.
The applicable edition is determined by the state in which the machine is used. As a result, different editions are valid throughout North America. It is therefore recommended that you always take note of the most recent edition.
NFPA 79 - Edition 2021
- Overvoltage protection is mandatory for industrial machines with safety-related circuits that are not yet adequately protected against overvoltages.
- Surge protection modules (SPD) must be UL listed.
- An SPD type 4 in the switch cabinet must correspond to the type of location of the machine and be marked accordingly.
- An SPD type 4 may only be installed by the control cabinet manufacturer.
NFPA 79 - 2018 Edition
- Overvoltage protection is mandatory for industrial machines with safety-related circuits (Safety).
- Surge protection modules (SPD) must be UL registered.
- An SPD type 4 in the control cabinet must correspond to the type of location of the machine and must be marked.
Our solution - your benefits
- VAL-US products are UL-Listed and can be universally applied to all site types
- No exceeding of the short-circuit current due to a high short-circuit resistance of 200 kA
- Simplified installation inspection by inspectors as regulations in accordance with NFPA 79 are complied with
- Products available throughout Europe, can be used and installed due to CE marking

Rittal - HUMMEL Cable glandsRead moreIf you want to protect your components properly against external influences, a strong enclosure alone is not enough. There are always cables running to and from your equipment, which is why you need a cable gland in addition to the enclosure for a complete solution for protecting your equipment. This ensures that the end of the cable running to your enclosure is securely attached. After all, your installation is only as good as its weakest link.

Sekisui AlveoRead moreFoam producer Sekisui Alveo has a large factory in Roermond. To support production and maintenance, warehouses and distribution points with thousands of different items are spread across the various halls. Think spare parts, personal protection equipment and consumables. The company cooperates intensively with itsme for management, such as recently with the step-by-step introduction of vendor managed inventory (VMI) for the grab stock of mechanical items.
-
IECRead moreTo control the expansion of a silo park, engineering & construction company IEC called on Breemes. Being involved in the engineering from the beginning, the electrical service provider was able to make smart proposals for both the low-voltage part and the PLC control. ‘We have always been able to find each other well and when changes occurred, we were quickly on the same page with Breemes.’
-
Heliox - Charged for DeliveryRead moreHeliox, a developer and manufacturer of charging systems for electric buses and trucks, was already working with itsme when production still took place in the Netherlands. Today, production has shifted to Slovakia, Portugal, and Moldova, and is also happening in the US. itsme remains the “irreplaceable” partner for the supply of electrical components and cable harnesses.
-
BLOK System SupplyRead moreBlok System Supply and itsme have maintained an intensive relationship for many years. Early last year, this was further deepened with electronic data exchange via the Smart Connected Supplier Network. ‘It saves an enormous amount of time and reduces errors. We always have real-time information automatically.’ However, time for personal contact is not saved. ‘That is precisely what makes itsme a very nice party to work with.’
