HV FUSES - FERRAZ SHAWMUT
Ferraz Shawmut Acquired GE Fuses in December 2007
Limitor High Voltage Fuses
Ferraz Shawmut fuses provide circuit protection to high voltage electrical systems to IEC60282-1. The expertise is centered on the circuit protection of high voltage transformers in the power distribution networks with solutions including high voltage Limitor® fuses for overhead line protection, oil-tight high voltage fuses and fault indicators, especially the Nortroll® products.
Ferraz Shawmut also provide North-American and European (DIN) standard high voltage motor protection fuses and circuit protection fuses for potential transformers and capacitors.
High voltage electricity distribution systems supplying industrial plants, shopping centres, hospitals, schools and commercial projects often require improved overcurrent protection.
Ferraz Shawmut current limiting high voltage fuses are specified for enhanced over-current protection and noiseless service. Ferraz Shawmut current limiting fuses restrict the damage to high voltage electrical equipment by limiting the let through energy at the fault.

Current Limiting Fuses 9F60 Series - Capacitor Fuses.
Ferrax Shawmut fuses are available for use with high voltage motors, transformers, capacitors and circuit-protection equipment.
Ferraz Shawmut Capacitor Fuses - 9F60 Series - 25-80A - 5.5kV
Ferraz Shawmut Capacitor Fuses - 9F60 Series - 15-40A - 9.52kV
Current Limiting Fuses 9F60 Series - Power .
Ferraz Shawmut current limiting fuses are designed not only to interrupt the high-fault currents but also to interrupt low-fault currents down to 3 times their continuous rating.
Ferra Shawmut Power Distribution Fuses - 9F60 Series - EJ1 EJ01
Current Limiting Fuses 9F62 Series - General Purpose .
Ferraz Shawmut general purpose current-limiting fuses are designed to interrupt low and high fault currents down to 1.6 to 2.2 times their continuous rating. This type of Ferraz Shawmut fuse is defined in the IEEE Std. C37.40-1993 as "a fuse capable of interrupting all currents from the rated interrupting current down to the currrent that causes melting of the fusible element in less than one hour".
Ferraz Shawmut general purpose fuses are available from 5.5kV to 15kV and 20 to 900A.
