NEW gR-CLASS

OPTIMAL PROTECTION OF POWER EQUIPMENTThanks to recent technological developments, Ferraz Shawmut todaymarkets gR-class PROTISTOR® fuses capable of clearing all types of over-loads, from low multiples of current ratings up to very high short-circuitcurrents. Enhanced performance enables these fuses to provide solu-tions to many previously unsolved problems in power electronics: pro-tection of cables without the use of additional components, protectionof equipment from fire hazards, selective coordination of different fuseswithin a single power distribution installation...

SELECTIVE COORDINATIONgR-class semiconductor fuses can be utilized in association with gI and gG-classlow voltage power distribution fuses of the same current rating, installed upst-ream. In a “selectively coordinated“ distribution installation, melting is limitedto the fuse associated with the faulted circuit, while upstream fuses remainintact. This prevents unnecessary down-time due to power blackouts in non-faulted branches.

FERRAZ SHAWMUT EXPERTISEgR-class fuses should be used in the design of low voltage equipment and in the protection ofpower 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 aRfuse 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 pro-tection, safety and reliability, along with reduced risk of replacement errors and assembly costs.

aR-CLASS vs. gR-CLASSaR-class fuses feature a high minimum inter-rupting current as compared with their cur-rent rating. The primary time-current charac-teristic of aR-class fuses is the CC’ curve,above which another protection device mustbe associated. The gR-class fuse representsconsiderably improved performance in semi-conductor protection.

NEW gR-CLASS

OPTIMAL PROTECTION OF POWER EQUIPMENTThanks to recent technological developments, Ferraz Shawmut todaymarkets gR-class PROTISTOR® fuses capable of clearing all types of over-loads, from low multiples of current ratings up to very high short-circuitcurrents. Enhanced performance enables these fuses to provide solu-tions to many previously unsolved problems in power electronics: pro-tection of cables without the use of additional components, protectionof equipment from fire hazards, selective coordination of different fuseswithin a single power distribution installation...

SELECTIVE COORDINATIONgR-class semiconductor fuses can be utilized in association with gI and gG-classlow voltage power distribution fuses of the same current rating, installed upst-ream. In a “selectively coordinated“ distribution installation, melting is limitedto the fuse associated with the faulted circuit, while upstream fuses remainintact. This prevents unnecessary down-time due to power blackouts in non-faulted branches.

FERRAZ SHAWMUT EXPERTISEgR-class fuses should be used in the design of low voltage equipment and in the protection ofpower 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 aRfuse 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 pro-tection, safety and reliability, along with reduced risk of replacement errors and assembly costs.

aR-CLASS vs. gR-CLASSaR-class fuses feature a high minimum inter-rupting current as compared with their cur-rent rating. The primary time-current charac-teristic of aR-class fuses is the CC’ curve,above which another protection device mustbe associated. The gR-class fuse representsconsiderably improved performance in semi-conductor protection.
