480Y/277V 3-Phase AC Surge Protector, 3P+N Type 2 SPD, DIN Rail For TN/TT systems; 20kA In/40kA Imax, L-N/N-PE protection, pluggable modules, remote signaling, red/green indicator

3+1 Three-Phase
Surge Protection: This 3 phase surge protector uses a coordinated 3+1 design with three MOV paths and one GDT path, helping protect three-phase electrical systems from lightning surges and transient overvoltage.
40kA High Discharge Capacity: Rated for 20kA nominal and 40kA maximum discharge current under 8/20s waveform, this lightning surge protector delivers robust surge handling for industrial and commercial power distribution.
DIN Rail Modular Installation: The plug-in four-module structure makes this DIN rail surge protector easy to install in electrical panels, distribution boards, and control cabinets, while allowing quick cartridge replacement during maintenance. Status Window &
Remote Signal Contact: Built with a green/red visual indicator and remote signaling dry contacts, this SPD with dry contact supports fault monitoring, alarm connection, and easier maintenance management.
For Industrial Three-Phase Systems: Designed for TN and TT three-phase power grids, this industrial surge protection device is suitable for factories, automation cabinets, control panels, low-voltage distribution systems, and lightning-prone facilities
