The POWERSET BC-385/3/FM is a specialized combined lightning current and surge arrester designed for 3-phase TN power supply networks. This device is compliant with Type 1+2/Class I+II standards, effectively integrating both protective earth (PE) and neutral (N) conductors into one unit.

It consists of three FLT 35 CTRL-4.0 devices and three VAL-MS 400/FM units, complete with necessary jumpers and labeling. The arrester operates within a voltage range of 230/400 V AC and features a nominal discharge current of 20 kA (8/20 µs) and an impulse discharge current of 35 kA (10/350 µs). The unit is mounted on a 35 mm DIN rail and has a weight of approximately 976.5 g including packaging.

This model supports an operational temperature range from -40 °C to 80 °C and can withstand humidity levels from 5% to 95%. It also includes an optical surge protection fault message indicator and a remote indication contact for monitoring purposes. The robust design ensures a degree of protection rated at IP20, provided all terminal points are utilized. Compliance with EN 61643-11 standards further certifies its reliability in surge protection applications.
