DSJ Electrical Co., Ltd. Advances Arc-Resistant Switchgear Safety with Proven Technology and Project Expertise

Every year, over 30,000 arc flash incidents occur worldwide, resulting in thousands of injuries and fatalities. These statistics highlight the critical need for robust electrical safety solutions, particularly in industrial and commercial power systems. Recognizing this urgent challenge, DSJ Electrical Co., Ltd. offers a comprehensive line of low- and medium-voltage arc-resistant switchgear designed to protect both personnel and equipment from the devastating effects of arc flash events.

Independently tested by KEMA, DSJ’s switchgear fully meets ANSI/IEEE C37.20.7 standards and features Type 2B-compliant enclosures. This ensures protection across all critical compartments—including breaker, bus, and cable sections—even when instrument doors are open. For low-voltage applications, DSJ’s Metal-Enclosed Arc-Resistant Switchgear has been third-party verified to withstand internal arcing faults up to 85kA, providing six-sided arc resistance while maintaining accessibility in compliance with IEEE C37.20.7 Type 2B standards.

Safety is further reinforced by adherence to NFPA 70E, with hazard risk ratings of zero when breaker doors are closed and latched. The switchgear is configurable to UL 1558 or UL 891 standards, offering flexible integration into a variety of applications and footprint requirements. These features allow DSJ to meet the growing demand for reliable, standards-compliant arc-resistant solutions across multiple industries.

Beyond technical specifications, DSJ has a strong track record of successful project implementation. Notably, the company collaborated with AMPERESAND, a leading solid-state transformer manufacturer, to develop 13.8kV arc-resistant switchgear for their Gen 3 Pilot Switchgear project. This partnership demonstrates DSJ’s ability to deliver customized, high-performance solutions for complex power systems while maintaining rigorous safety standards.

DSJ’s product line is specifically designed to address the most pressing challenges in arc flash mitigation. By combining cutting-edge engineering, independent certification, and practical project experience, DSJ provides customers with switchgear that is not only compliant with international standards but also immediately deployable in active production environments. Unlike products that require post-design certification adjustments, DSJ’s solutions are ready to integrate, minimizing risk and maximizing operational efficiency.

The company’s approach emphasizes both safety and flexibility. Customers can opt for white-label or OEM configurations, including blank housings or customized logos, with repeatable branding for future orders. This level of customization, combined with proven reliability, positions DSJ as a preferred partner for organizations seeking dependable arc-resistant switchgear for critical electrical infrastructure.

In summary, DSJ Electrical Co., Ltd. stands at the forefront of arc-resistant switchgear technology, offering a unique combination of comprehensive safety features, international certification, flexible configurations, and demonstrated project experience. As arc flash risks continue to challenge the power industry, DSJ remains committed to providing solutions that safeguard personnel, protect equipment, and support reliable electrical operations worldwide.
