lorem ipsum — Voltage protection level diagram BXTU

To ensure high availability of the signal circuits, the integrated LifeCheck feature allows a quick check of whether the arrester is pre-damaged.

Optimally adapted voltage protection level with integrated actiVsense technology ensures protection of terminal equipment.

DIN rail mounting by means of integrated earthing contact.

The protection module of the pluggable arrester safely snaps into the base part, thus ensuring vibration and shock resistance.

BXTU ML4 BD 0-180

Space-saving combined lightning current and surge arrester module with actiVsense technology and RFID LifeCheck for protecting two pairs (same or different operating voltage) of balanced interfaces with galvanic isolation. Automatically detects the operating voltage of the useful signal and optimally adapts the voltage protection level to it.
