Product Description
This 4-pole Type 2 surge protection device is engineered for 320Vac three-phase distribution systems, mounted in LPZ0B-LPZ1 distribution cabinets. With 40kA maximum discharge capacity, it diverts heavy lightning surges and limits voltage protection level ≤1.5kV to prevent transient overvoltage damage on industrial controllers and building power meters. Anti-vibration modular structure fits constantly vibrating factory cabinets, with built-in thermal release to avoid overheating risks. Front green/red status window provides local visual check, while NC/NO remote contacts connect to central monitoring systems. PA6 V0 flame retardant housing fits low-voltage panels in factories, shopping malls and office buildings.
