Product description Compact 4P surge protector designed for three phase four wire AC systems. Rated for AC 385V with surge current capacity in the 30 to 60 kA range, this unit reduces the risk of equipment damage from transient overvoltages and voltage spikes while fitting into standard electrical distribution panels. Key benefits Reliable surge handling: Rated surge current of 30 to 60 kA provides robust attenuation of transient events to help preserve connected equipment. Designed for three phase systems: Four pole configuration supports three phase plus neutral installations for consistent protection across all conductors. Space efficient: 4P footprint fits distribution boards without requiring excessive panel space. Simple integration: Intended for lineside installation in distribution or branch panels to protect downstream devices and circuits. Main features and attributes Function: Surge protection for AC power lines to limit the impact of transient overvoltages on electrical and electronic equipment. Compatibility: Suited for three phase four wire AC systems up to 385V. Size: 4P configuration for fullphase coverage including neutral. Performance: Surge current capability specified between 30 kA and 60 kA, suitable for commercial and light industrial surge environments. Installation context: Intended for use inside electrical distribution panels and switchboards. Practical use scenarios Commercial building distribution board: Install on the main incoming panel to protect lighting, HVAC, and tenant equipment from external and internal surges. Industrial control cabinet: Protect programmable logic controllers, drives, and sensors in machine control panels fed by three phase supply. Server room or telecommunications closet: Provide coordinated surge protection at the panel feeding UPS systems and rack PDUs to reduce risk of transient damage. What it solves Reduces the likelihood of equipment failure and service interruptions caused by transient overvoltages. Provides consistent protection across all three phases and neutral, maintaining balanced protection for multiphase systems. Helps extend the service life of sensitive electronic loads by limiting exposure to surge events. Installation and selection tip Choose this 4P unit for three phase four wire installations where a rated AC voltage near 385V and a surge capacity of 30 to 60 kA match system requirements. Verify coordination with upstream and downstream protective devices when integrating into existing power distribution. This surge protector is a straightforward component for adding transient protection to three phase electrical installations where a 4P solution and the specified voltage and surge capacity are required.
