EYZAO ESCB series dedicated surge backup protector (SSD) passes the NB/T 42150-2018 “Low-voltage Surge Protector Dedicated Protective Device” conformity assessment, which can quickly cut off the pathway when SPD short-circuit occurs due to deterioration and grid fault, and the cut-off current is less than 3A, which can prevent the SPD from starting a fire. When a lightning strike occurs, the SSD connected in series at the front of the SPD can ensure that the lightning current flows through the outdated non-disconnecting, non-damage, lightning protection continues to be effective.

EYZAO ESCB series SPD backup protector short-circuit breaking capacity of up to 100kA, to protect the SPD from TOV damage, in the surge occurs at both ends of the residual voltage is lower, the corresponding SPD branch of the effective voltage protection level of Up/f is lower, so that the equipment can be better protected, is the low-voltage power distribution system surge protector ideal backup protection device.
