Luxembourg, as a premier global financial hub and a burgeoning center for high-tech industry, maintains some of the highest electrical safety standards in the world. With the Grand Duchy's aggressive transition toward green energy—evidenced by the National Energy and Climate Plan—the demand for sophisticated Type B RCD Current Transformers has reached an all-time high. Unlike standard Type A sensors, Type B residual current devices are essential for detecting smooth DC leakage, a critical requirement for Luxembourg's extensive EV charging network (Chargy), high-frequency inverter systems, and state-of-the-art data centers.
Our role as leading exporters and manufacturers for the Luxembourgish market involves providing components that meet IEC 62423 standards. From the heavy steel manufacturing plants in Esch-sur-Alzette to the digital headquarters in Luxembourg City, our Type B RCD transformers ensure operational continuity and human safety in environments where DC leakage current is a constant risk.

Luxembourg has one of the highest EV adoption rates in Europe. Our Heyi/Asct Type B sensors are specifically designed for Luxembourg’s public and private charging piles, providing 6mA DC detection to prevent blindings of Type A RCDs upstream.
Commercial solar parks in the northern Gutland region utilize hybrid inverters. Our transformers detect AC and DC residual currents, ensuring these systems comply with Luxembourg's strict grid injection regulations.
In the heavy industries surrounding Belval, variable frequency drives (VFDs) are ubiquitous. Our split-core RCD sensors allow for retrofitting without dismantling existing cabling, a major advantage for brownfield renovations.
The Kirchberg district relies on high-density power distribution. Our high-precision transformers provide real-time leakage monitoring to prevent electrical fires in mission-critical banking infrastructure.
Fujian Smrtr Technology Co., Ltd. Zentar® is a premier global manufacturer of magnetic components for electrical safety and power measurement, established in 1993. With advanced operating facilities in Xiamen and a dedicated workforce of approximately 410 specialists, we have become a trusted partner for Luxembourgish electrical wholesalers and engineering firms.
Our commitment to excellence is backed by a robust R&D team led by university professors and 20 senior engineers, ensuring that every Type B RCD current transformer we export to Luxembourg is at the cutting edge of technology. We implemented ISO9001 in 2002 and have since upgraded to IATF 16949, the gold standard for automotive-grade quality control.
With an annual capacity of 50 million magnetic components and a 40,000-square-meter state-of-the-art workshop, we provide the scalability and technical precision required for the most demanding Luxembourgish infrastructure projects. Whether it's split-core CTs for energy auditing or high-accuracy sensors for RCD modules, Zentar® delivers reliability.

As Luxembourg moves toward "Smart City" concepts, the complexity of the electrical load increases. Modern equipment, such as frequency-controlled pumps in Luxembourg's water treatment facilities or elevators in the Munsbach business park, generates complex residual currents. Standard Type AC or A RCDs can become "blinded" by DC leakage, failing to trip during a dangerous ground fault.
Our Type B RCD Transformers are engineered to address this. By using advanced magnetic cores and fluxgate sensing technology, our sensors provide a frequency response from DC up to several kilohertz. This level of expertise ensures that Luxembourgish engineers can design systems that are not only compliant with VDE 0100-530 (often referenced in the region) but are also future-proofed against the evolving harmonics of the modern grid.
We understand the logistics and certification requirements for the Benelux market. Our products are CE marked and designed to integrate seamlessly into DIN-rail mounted protection devices or custom PCB solutions for Luxembourg's high-tech OEMs. By choosing Zentar®, you are partnering with a manufacturer that understands the nuances of the Luxembourgish market—from the requirement for compact footprints in urban distribution boards to the extreme durability needed for outdoor EV charge points.
