SSD (SPD Specific Disconnector)

The SPD-specific backup protector, also known as SSD (SPD Specific Disconnector), is a device that can withstand the expected surge current at the installation location of the protected surge protector (SPD) and interrupt the power frequency overcurrent generated due to the failure of the SPD. It also features the characteristic of operating at small power frequency currents, and is also referred to as SCB.
