4P Surge Arrester, 60kA Visible Window (Imax: 40kA)

【Ball Locking】The modular ball locking mechanism snaps onto standard 35mm DIN rails, preventing movement under high electrical loads and ensuring a stable, vibration-resistant connection.
【Status Window】The clear viewing window with red and green indicators instantly displays the protection status; A red flag signals a disconnection, allowing for immediate visual inspection without touching the device.
【Fireproof PC Housing】The high-strength polycarbonate housing with flame-retardant properties prevents ignition due to electrical arcs, maintaining circuit integrity during abnormal overvoltages.
【Plug-in Module】The removable core component allows for quick module replacement without disassembling all the basic wiring, significantly reducing downtime for maintenance in residential installations.
【Crack-Resistant Terminal】The terminal uses a crack-resistant locking system that securely holds the conductors, facilitating simple wiring while preventing loosening due to thermal expansion in domestic distribution boxes.
