What is a DC Surge Protective Device？
DC Surge Protective Devices (SPD) are essential for safeguarding electronic systems from voltage spikes, ensuring both reliability and efficiency. Their ability to absorb and redirect excess voltage helps ...
• ventilation slot The ventilation slot and cooling chamberhave strong
heat dissipation performance.
• red copper terminal block Thickness up to 1.0mm.
• indication window design Signal whether the fused core is fused or
not(light on fused, off on normal)
