Certain minimum operating voltage/current 20 V-100 mA NEW gR-CLASS t OPTIMAL PROTECTION OF POWER EQUIPMENT Thanks to recent technological developments, Ferraz Shawmut today markets gR-class PROTISTOR(R) fuses capable of clearing all types of overloads, from low multiples of current ratings up to very high short-circuit currents. Enhanced performance enables these fuses to provide solutions to many previously unsolved problems in power electronics: protection of cables without the use of additional components, protection of equipment from fire hazards, selective coordination of different fuses within a single power distribution installation... t C 100A "aR" 100A "gR" 2h C' 30s 300A Example: 100A aR vs. 100A gR I minimum interrupting current I 110A SELECTIVE COORDINATION aR gR gR-class semiconductor fuses can be utilized in association with gI and gG-class low voltage power distribution fuses of the same current rating, installed upstream. In a "selectively coordinated" distribution installation, melting is limited to the fuse associated with the faulted circuit, while upstream fuses remain intact. This prevents unnecessary down-time due to power blackouts in nonfaulted branches. Relay gG 100A Example of selective coordination Before gR 100A gR 100A After M M aR-CLASS vs. gR-CLASS FERRAZ SHAWMUT EXPERTISE aR-class fuses feature a high minimum interrupting current as compared with their current rating. The primary time-current characteristic of aR-class fuses is the CC' curve, above which another protection device must be associated. The gR-class fuse represents considerably improved performance in semiconductor protection. gR-class fuses should be used in the design of low voltage equipment and in the protection of power electronics equipment. Designers can often substitute a gR-class fuse for an aR-class fuse (10x38, 14x51, 22x58, PSC 000 and 17x49 DIN80 or BS 88-4) but the reverse is not true: an aR fuse can never replace a gR fuse. Start protecting your new equipment with gR-class fuses today. The application of gR class fuses, with current ratings less than 100 Amps, offers enhanced protection, safety and reliability, along with reduced risk of replacement errors and assembly costs. 12/04 SCAC229
