GRL RT18 Fuse Holder can be applied in both AC and DC area.It is suitable for AC 50HZ/60HZ, rated insulation voltage up to 800V, and rated thermal current up to 125A. It can carry fuse with maximum size 22× 58 in various use categories (gG, aM, aR, etc.). GRL RT18 fuse holder can withstand the conventional thermal current and the expected short-circuit impulse current to 100kA. GRL RT18 fuse holder comply with the national standard GB/T13539.2 and the International Electrotechnical Commission standard IEC60269-2.
Characteristics
——Insulating material ,of high strength and high temperature resistance.
——T2. Conduct material is T2 copper.
——External locking device is available,which can be locked when the fuse holder is closed and help avoid misoperation.
——The fuse holder can be combined from 1 pole to 2 pole,3pole and 3pole +N pole.
——Indicator is available,which indicates that the fuse has been blown if the lamp light up.
—— There are 2 lamps.1 lamp is the backup of the other.It avoids lamp failure during long-term work.And fast maintenance can be ensured.

RT fuse switch disconnector is one of classical fuse holder, GRL RT series fuse switch disconenctor with completely new structure design .
It with two indicator lights and special outlook,the raw materials are PA66-V0 flame retardant plastic and copper contacts. There are 3 models:32A frame for 10mmx38mm cylinder fuse link, 63A frame for cylinder 14mm*51mm cylinder fuse link, 125A frame for 22mm*58mm cylinder fuse link. There are AC type and DC 1000V type for different application. AC type are normally used as a protective switch in power distribution system and industry power control system; DC1000V fuse holder are widely used in Photovoltaic Solutions. The din rail design makes installation easy and convenient. And it can be combined freely with connecting accessary from 1P to 2P,3P,4P(3P+N).
As a qualified new product in 2021, we have got TUV certificate and test report for GRL RT fuse holders.
