Surge Protector, Safe Surge Protective Device Rail Installation Quick Response Speed Resistance Strong Carrying Capacity for Factory (4P 385V)

1. SURGE PROTECTION: This protector will turn on quickly within nanoseconds when there is a surge overvoltage, guide the surge overvoltage into ground, protect electrical equipment. 2. EXCELLENT PERFORMANCE: This surge protector has quick response speed and strong carrying capacity, prevent the household power grid from excessive impact. 3. WORKING STATUS INDICATION: Designed with indication window, which effectively reflect the working status, green color means normal, red color means fault. 4. HIGH SAFETY: The surge protector adopts PC shell, which is fire retardant and resistance, adopts insulated terminal blocks, more reliable and safe. 5. SIMPLE USE: The protector supports hot line operation and is easy to use, adopts modular design and 35mm electrical rail installation method, convenient to install. Specification: Item Type: Surge Protector Material: PC Color: White Maximum Discharge Current (Imaximum): 20KA Nominal Discharge Current (In): 10KA Protection Level (Up): 1.5KV Protection Grade: IP20 Response Time: ? 25ns Maximum Wire Diameter: 35 hard wire or stranded wire (mm²) Recommended Connection: 4-25 (mm²) Installation Method: 35mm electrical guide rail installation Ambient Temperature: - 40? to +80? Main Structure and Working Principle: In a three phase four wire system, protectors are connected between three phase wires and one neutral wire to ground. Under normal circumstances, the protector is in a high resistance state, when the power grid deals with surge overvoltage due to lightning strike or other reasons, the protector will turn on quickly within nanoseconds, and introduces the voltage overvoltage into the ground, thus protecting the electrical equipment on power grid. When the surge voltage passes through the protector and disappears, the protector changes to a high resistance state again, so as not to affect the normal operation of the power grid. Package
