nVent SCHROFF Onboard Varistar Launches Railway Certified Enclosure Designed to Protect Electronics Within Rolling Stock

nVent, a global leader in electrical connection and protection solutions, today introduced the nVent SCHROFF Onboard Varistar – a steel enclosure designed, tested and certified to protect critical 19” mounted electronics used in modern signaling and communications for rolling stock.

nVent developed the Onboard Varistar to provide a modular platform for rail signaling customers. Flexibility is a key differentiator of the Onboard Varistar, which offers space savings through various sizes, accessories and bulkhead fixing options for easy adaptation to specific application requirements.

nVent’s modular and pre-certified rack solutions, which are designed and validated for each specific project, can save customers time and money compared to proprietary solutions. The project delivery cycle can be vastly reduced by adopting nVent SCHROFF modular Onboard Varistar and the available accessories, including bulk head fixing options.

Railway customers can design with confidence knowing the Onboard Varistar has been tested to railway industry standards, including shock and vibration (EN50155), electromagnetic compatibility (EN61000-5-7), low smoke zero halogen (EN45545-2) and welding certification (EN15085-2).

For more than 35 years, nVent SCHROFF certified electronic packaging solutions have been trusted to protect electronics in both onboard and trackside rail signaling and communications. For more information, visit
