ZR-C385-60 4P AC Surge Protective Device (SPD)

Our ZR-C385-60 SPD is engineered to intercept and discharge transient overvoltages in 220V/385V AC systems, such as those caused by lightning strikes or grid switching operations. It utilizes advanced voltage-clamping technology to quickly limit residual voltage and divert surge currents to the ground, protecting downstream electrical equipment from damage.

With a 4-pole configuration, this SPD is compatible with three-phase AC systems, offering comprehensive protection for L1, L2, L3, and N lines. Its compact DIN-rail mount design (108×50×85mm) allows for easy installation in distribution cabinets, while the PC flame-retardant shell enhances safety under extreme conditions. The built-in visual status indicator provides real-time monitoring, enabling quick identification of fault conditions and timely maintenance. As a key component of a multi-level lightning protection system, it acts as the secondary defense layer, effectively mitigating residual surge energy and ensuring stable system operation.

Key Features
