As Cambodia undergoes a rapid industrial transformation under the "Power Development Plan (2022-2040)", the demand for sophisticated electrical safety components has skyrocketed. Unlike traditional Type A or AC residual current devices, the Type B RCD Current Transformer is engineered to detect not only sinusoidal AC, but also pulsed DC and smooth DC residual currents. This technical superiority is critical for the Kingdom's growing Electric Vehicle (EV) charging infrastructure, high-rise solar integration, and automated manufacturing sectors.
Cambodia's commitment to renewable energy requires advanced DC fault protection. In solar PV installations, smooth DC leakage can blind traditional RCDs, making Type B sensors a mandatory safety standard for new projects in Phnom Penh and beyond.
With the surge of EV adoption in Southeast Asia, Type B RCD sensors (IEC 62955 compliant) ensure that EVSE (Electric Vehicle Supply Equipment) remains safe from 6mA DC leakage, protecting both the vehicle and the local power grid.
In the garment and heavy machinery industries of the Sihanoukville Special Economic Zone, frequency converters often generate high-frequency residual currents. Type B technology provides comprehensive protection against these complex waveforms.
Fujian Smrtr Technology Co., Ltd. (Zentar®) is a premier global manufacturer specializing in magnetic components for electrical safety and power measurement since 1993. With over three decades of engineering excellence, Zentar® has become a trusted partner for Cambodian industrial developers and global energy firms.
Our commitment to E-E-A-T (Experience, Expertise, Authoritativeness, and Trustworthiness) is reflected in our IATF 16949 and ISO9001 certified processes. We employ over 410 professionals, including a research team led by professors and 20 senior engineers, ensuring that every Type B RCD current transformer meets the highest international safety standards.
Our Type B sensors are designed to meet the specific grid fluctuations found in Southeast Asia. We provide full compliance documentation for Cambodia’s Ministry of Mines and Energy (MME) standards, ensuring your project approvals are seamless.
Strategically located in Fujian/Xiamen, we offer rapid shipping routes to Sihanoukville and Phnom Penh. With the RCEP agreement, importing components from our factory offers significant tax advantages for Cambodian businesses.
We provide on-site technical consultation for large-scale infrastructure projects in Cambodia. From circuit design to final integration, our engineers bridge the gap between Chinese manufacturing efficiency and local operational needs.
