JHUSLKG series is used for safety grounding of electrical systems. Its core function is to provide a common, low-impedance, and highly reliable connection point for the grounding conductors of equipment inside the cabinet, ensuring that all equipment that needs to be grounded can be safely and effectively connected to the main grounding busbar or grounding bar.

When an insulation fault occurs in the equipment and causes the casing to become energized, the grounding terminal can quickly conduct the fault current to the ground, causing the upstream circuit breaker or leakage protection device to trip and cut off the power supply, thereby preventing electric shock to personnel.
