Betterfuse 3x10mm Time Delay Ceramic Cartridge Fuse 334 1.6A 2A 3.15A 5A 6.3A 10A
General Description Of The Ceramic Cartridge Fuse 334
334 series time-lag low breaking capacity fuse with printed circuit
boards is used in a large
variety of applications. The 3.6x10mm device is constructed of a
ceramic tube with electroplated brass end caps. The 334 series with
250 VAC rating and 35A or 10In (10 times ofrated current) breaking
capacity, offers excellent quality and is 100% tested for cold
resistance and precise length.Mainly used in lighting, power
adapters, LED drive power, power equipment, small appliances and
control panels, etc.
