In today’s evolving electrical and energy sectors, ensuring the safety, reliability, and efficiency of power systems is more critical than ever. GRL Electric is at the forefront of providing advanced electrical protection and energy management solutions.
Today we mainly introduce GRL fuses, knife switches, and fuse disconnector switches. Through continuous innovation and rigorous testing, we deliver solutions that guarantee the safety and longevity of electrical systems.
GRL’s fuse products are integral to protecting electrical systems from overcurrent situations. Fuses act as a safeguard, preventing damage to components by disconnecting power when current exceeds safe levels.
GRL DNESS series energy storage fuses are specifically designed for high-energy applications, such as energy storage systems and critical power supplies. These fuses are TÜV certified and are capable of handling up to 3000A, making them ideal for large-scale energy storage systems that demand high current protection.
The DNESS energy storage fuse link is engineered to handle high-energy surges typically seen in battery storage systems. These fuses protect battery systems from overcurrent conditions, reducing the risk of thermal runaway and fire, and ensuring compliance with international safety standards like IEC and UL.
Our gG fuses are ideal for general protection, while aR fuses are designed specifically for protecting semiconductor devices and circuits with higher inrush currents. Both fuse types offer precise time-delay functions to accommodate temporary surges without unnecessary interruptions.
GRL’s knife switches and disconnector switches provide reliable electrical isolation in high-voltage environments. Knife switches are manual switching devices that ensure the safe isolation of electrical circuits, while fuse disconnector switches ensure full separation of electrical connections, especially under load conditions.
The DNH51 DC knife switch is another crucial product in GRL’s portfolio, particularly for use in DC applications such as PV systems. With robust, flame-retardant housing and excellent electrical performance, this knife switch ensures reliable circuit isolation in photovoltaic power plants, allowing for safe maintenance and system upgrades.
Our fuse knife switch products combine fuse protection with knife switch functionality, offering a compact solution for disconnecting circuits while ensuring fast overcurrent protection. These switches are designed to operate in harsh environments, with high reliability and safety.
Our DNH1 series fuse switch disconnectors, including PV systems and industrial electrical networks, are designed for high-voltage and high-current applications. With an increased rated voltage of up to 1600V, the DNH1 fuse isolator switch is highly versatile and suitable for a wide range of applications, including energy generation, transmission, and distribution.
Busbar systems play a crucial role in electrical distribution networks, providing an efficient way to transmit high amounts of current across circuits while ensuring safety and minimizing the risk of overload. GRL’s 60mm pitch busbar system is designed to offer flexibility and scalability, making it suitable for both residential and industrial applications.
Our busbar supports and copper busbar products are engineered to support various busbar configurations, providing stability and ease of maintenance. The busbar system is optimized for minimal electrical resistance and maximum safety, with components that allow for quick assembly and disassembly during system upgrades or maintenance.
Our busbar support products are designed for easy installation and alignment. These supports are compatible with various busbar configurations and help reduce the risk of mechanical stress and thermal expansion, enhancing the longevity and performance of electrical systems.
Copper is the preferred material for busbar systems due to its excellent electrical conductivity. GRL’s copper busbars are corrosion-resistant and capable of handling high currents, making them ideal for power distribution in commercial and industrial settings.
