Surge Arrester 4P 8kA(10/350) CLASS T1+T2 (B+C) SCHELINGER

The SCHELINGER BEMK-A51-SPD02-4P-B+C is a high-performance surge protective device designed for main distribution boards in buildings. It combines Type 1 (Class B) and Type 2 (Class C) protection in a single compact unit, capable of handling direct lightning strikes with a maximum discharge current of 8 kA per pole (10/350 µs waveform). This 4-pole configuration (3L+N+PE) is suitable for TN-S, TN-C-S, and TT systems, providing comprehensive protection for sensitive electrical and electronic equipment against both direct and indirect surge events.

With a low protection level Up of ≤ 1.5 kV (L-N) and ≤ 1.2 kV (N-PE), this arrester ensures minimal let-through voltage, safeguarding downstream devices. It features a robust design with thermal and overcurrent disconnection, visual status indication, and a pluggable module for easy replacement. Compliant with EN 61643-11 and IEC 61643-11 standards, it is ideal for residential, commercial, and industrial applications where reliable surge protection is critical.
