AC SPD Surge Protector Low Voltage Distribution Household Arrester Protection Device Model: LBO 4P Quantity: 1PCS Type: Residual Current Smart device: No : Yes Color: White Key benefits Protects low voltage distribution panels and connected equipment from transient overvoltage and surge events by diverting surge current away from sensitive devices. Four pole design supports threephase systems plus neutral, making it suitable for household and small commercial distribution boards. discharge capacity options noted in product specifications to handle large surge currents found in lightning strikes and switching events, reducing the likelihood of equipment damage. Main features Rated voltage: 385V AC for use in low voltage distribution systems. Pole configuration: 4P for three phase plus neutral protection. Surge capacity: specifications include ranges of 20kA to 40kA and 30kA to 60kA in the product listing; choose the appropriate module based on site requirements. Type: Residual current surge protective device for combined surge and leakage monitoring function. Color: White housing for easy integration into distribution panels. No concern chemicals present. Why this product solves common problems Prevents costly downtime and component replacement by limiting surge energy reaching downstream equipment. Centralized protection at the distribution board simplifies wiring and provides coordinated protection for branch circuits. Available discharge capacity ranges allow selection for varying exposure levels and installation environments. Compatibility and application Designed for low voltage distribution panels in residential and small commercial installations. Suitable for protecting household electrical systems, small office equipment, and light industrial control panels. Applicable for use with renewable energy inverters and battery storage systems when installed in the building distribution board. Typical use scenarios 1. Residential main distribution board: Install at the service entry to protect household appliances, home entertainment systems, and smart home controllers from transient overvoltage. 2. Small commercial office: Protect computers, network equipment, and lighting control panels from surge events originating on the utility supply. 3. Renewable system distribution: Use in the AC distribution panel downstream of inverters to reduce surge exposure to connected electronics. Installation and selection notes Select the appropriate discharge capacity module for site surge exposure. Product information lists multiple capacity ranges. 4P configuration requires wiring to the three phase lines and neutral; installation should be carried out by a qualified electrician. Not a smart device; functions as a traditional residual current surge protection module. What is included One 4P surge protection switch module, model LBO 4P, in white. Technical summary Model: LBO 4P Type: Residual Current Poles: 4P Voltage rating: 385V AC Surge capacity references: 20kA 40kA and 30kA 60kA ranges as listed Quantity: 1PCS : Yes Smart device: No This device provides centralized surge protection for low voltage distribution systems and is suitable for residential and light commercial applications where 4P protection and discharge capacity options are required.
