50kA Type 1 Surge Protection Device 3P+N Class I Surge Arrester for DIN Rail 35mm Mounting

The BR-50GR 3P+N is a Type 1 / Class I lightning surge protective device (SPD) designed to protect low-voltage consumer installations against indirect lightning discharges. It combines a high-performance varistor with a thermal disconnection tripping device, delivering reliable 50kA lightning impulse current protection for demanding industrial and commercial environments.

• Iimp — Impulse current of Type 1 SPDs with a 10/350 μs waveform.
• In — Nominal discharge current of Type 2 SPDs with an 8/20 μs waveform.
• Imax — Maximum discharge current of Type 2 SPDs with an 8/20 μs waveform.
• Up — The residual voltage measured across the terminals of the SPD when In is applied.
