SPD - Surge Protective Device
Metaltex DIN-rail mount surge protection devices (SPD) are designed to divert transient voltage spikes caused by lightning strikes or switching operations to ground. Available in single-pole, two-pole, and three-pole versions, the range spans from Class I and II (for robust protection and main distribution boards handling currents up to 45 kA) to Class III (precise point-of-use protection for sensitive electronics such as PLCs or medical equipment), including models for photovoltaic systems. Manufactured in accordance with IEC standards, they streamline maintenance through a visual indicator window (green for operation/red for replacement) and a modular design featuring removable cartridges, allowing for quick replacement without disconnecting wiring from the base.
