Fast-acting ceramic fuses enhance safety

The C308F Bussmann series of fast-acting, ceramic tube fuses for intrinsic safety requirements used in hazardous environments such as network barriers and other equipment used in mines, oil drilling structures, gas stations, gas meters, chemical refineries and hazardous material transportation.

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 V and 250 mA for both alternating current and direct current power. These fast-acting fuses provide a high breaking capacity of 4,000 A in a 3 x 8.4-mm size. The fuses can be used in intrinsically safe devices 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.
