⚡ Key Features

350V AC maximum continuous operating voltage (Uc) — remains permanently connected to the live supply; clamping only activates during overvoltage events.
MOV (Metal Oxide Varistor) clamping technology — responds in nanoseconds (< 25ns) to clamp transient overvoltages before they reach connected sensitive electronics.
Visual end-of-life indicator — green flag (healthy) turns red when the MOV has absorbed its rated energy and must be replaced; ensures protection level is always verified.
35mm DIN rail mounting — installs inside the main distribution board at the point of entry; protects the entire downstream installation in a single device.
