Product name: AC SPD, Model CHT1 Description A compact, four pole surge protective device designed for three phase AC systems. The mini form factor fits space constrained distribution panels while providing surge handling suitable for 380 volt class installations. This non smart device offers straightforward overvoltage protection in a small package and contains no concern chemicals. Key benefits Protects equipment from transient voltage spikes and surges by diverting excess energy away from connected loads, helping to reduce the risk of downtime and component stress. Compact mini size makes it easy to install in crowded electrical cabinets and distribution boards. Four pole configuration supports three phase systems with neutral, providing broad compatibility for industrial and commercial mains circuits. Simple, non smart design keeps installation and operation straightforward without network or configuration requirements. Provided surge capacity range 3060KA for handling common surge events in power distribution environments. Main features and specifications Product name: AC SPD Model number: CHT1 Type: Mini Poles number: 4P Size designation: 385V 4P Rated voltage: 380V Product voltage: AC 385V Color specification: 3060KA Is smart device: No concern chemical: None Performance and compatibility Designed for use on three phase four wire systems at around 380 to 385 volts AC. Four pole layout supports protection of all phase conductors plus neutral where required. Compact footprint suits standard electrical distribution panels and equipment racks where space is limited. Typical use scenarios Protection for a three phase distribution board in a commercial building to reduce the impact of incoming mains transients on downstream equipment. Integration into industrial control panels to protect motors, drives, and PLC inputs from voltage spikes. Supplementary protection for renewable energy inverter input boards or generator distribution systems operating at 380 to 385 volts. Installation and operation notes This is a non smart, passive surge protective device. Installation should follow local electrical regulations and practices for surge protection, including correct connection to the system neutral and protective earth as required by the installation. Verify system voltage compatibility before installation to ensure the rated voltage and product voltage align with the target distribution system.
