Parallel-type (single-port) big through-flow 3-phase power supply lightning protection box series of products is used for Class 1 or Class 2 protection.
Product Features
Multi-chip paralleling technology offers good current equalization.
Allowance of big through-flow from multi-chip paralleling and combination guarantees long service life of the lightning-arresting system.
Protection of individual chips from overheating and impact current provides very high degree of safety for the lightning-arresting system and thoroughly avoids fire disasters.
Remote signaling device realizes damage alarming and facilitates control.
SPD deterioration indication.
Equipped with lightning stroke recorder.
Lead-in end of SPD equipped with air switch for protection against over current.
