Characteristic
1.Ceramic brazing sealing technology,to achieve the contact part of airtight packaging,no risk of arcleakage,ensure no fire,no burst
2.In the aitight package structure,the hydrogen-dominated gas is filled to effectively prevent the oxidationand burning of contact points,and the contact resistance is low and stable
3.250A 85ºC long time current carrying capacity
4.In response to abnormal conditions,it can break 10 times of over current
5.Insulation resistance up to 1000MQ(1000VDC),dielectric withstand voltage meet IEC60664-1 requirement
