Eaton Fast-Acting Ceramic Fuses Enhance Safety in Hazardous Environments for Mining, Refining, Oil Drilling and Other Industrial Applications
“Manufacturers of intrinsically safe barrier networks need fast-acting devices that prevent explosions in extremely hazardous conditions,” said Vincent Wang, global product manager for Eaton’s Electronics Division. “This fuse line offers advanced overcurrent protection that meets internationally-defined safety requirements where electrical equipment is required in the presence of highly volatile materials.”
Intrinsic Safety (IS) is universally recognized under the specification EN60079-11, which is a low-energy signaling technique that prevents explosions from occurring during industrial activity by ensuring that the energy transferred to a hazardous area is well below the energy required to initiate an explosion.
The ceramic tube construction of these fuses meets EN60079-11 standards for explosive environments and delivers a high interrupting rating for circuit protection up to 250 volts (V) and 250 milliAmperes (mA) for both alternating current (AC) and direct current (DC) power.
These fast-acting C308F fuses provide a high breaking capacity of 4,000 amperes (A) in a compact 3 x 8.4-millimeter size.
The C308F Bussmann series fuses can be used in intrinsically safe devices defined according to the international standard by the International Society for Automation (ANSI/ISA-RP12.6: less than1.5V, less than 0.1A, and less than 25 milliWatt during operation) such as contactors, thermocouples, LEDs, non-inductive potentiometers and resistors. They can also be used for non-simple devices such as transmitters, transducers, solenoid valves, and relays.
