OBT2 series surge protector

◎ Overview

According to the GB/T18802.1-2011 standard,the front end of the SPD loop must be connected in series to the overcurrent protection appliance required by the manufacturer.Because current fuses and microcircuit breakers cannot coordinate with SPD,when the power supply is abnormal or SPD deteriorates and fails, the fire and equipment are damaged by lightning,which has seriously affected the normal operation of production and operation!

At present,the miniature circuit breaker used with SPD can not be matched with the fllowing4points 1,lightning current impact is easy to damage a lightning protection failure;2,lightning impulse current residual voltage high equipment lightning protection reliability decreased;3,power frequency continuous current does not trip a power supply abnormal SPD fire;4,lightning impact trip a lightning protection failure.
