Ferraz Shawmut To Display Comprehensive Medium Voltage Fuse Line


NEWBURYPORT, Mass. - Ferraz Shawmut, a global leader in the field of circuit protection, will exhibit its comprehensive line of medium voltage circuit protection fuses, including E-Rated, R-Rated and PT fuses, at the 2010 IEEE/PES Expo.
Ferraz Shawmut's medium voltage fuses are used for the protection of capacitors, transformers or motors and have been designed to meet various mounting configurations or standards requirements.

Ferraz Shawmut's E-Rated Medium Voltage fuses deliver overload and short circuit protection of transformers and distribution lines. E-Rated fuses are general purpose, current-limiting fuses that will melt at a current as low as 1.7 times the fuse current rating up to its maximum interrupting rating. Also known as power distribution fuses, they range from 2.7kV to 38kV. E-Rated fuses are designed to withstand transformer magnetizing inrush current.

"Our customers find that our line of E-Rated and R-Rated medium voltage fuses are a more economical solution as compared to other circuit breaker options," said Jean Christophe Bertrand, Ferraz Shawmut Product Manager. "We also recommend customer's keep an inventory of fuses and spare parts to ensure continuously running applications and avoid costly downtime."

The company's line of R-Rate Fuses provide short-circuit protection for medium voltage motors and motor controllers. R-Rated medium voltage fuses range from 2.4kV to 15.5kV. These backup-type, current-limiting fuses will melt in the range of 15 to 35 seconds at a current equal to 100 times the "R" rating. The elements of these fuses are designed to withstand the cyclic motor-starting inrush current. They are not intended for overload protection. Full protection, short circuit and overload is achieved using other protective devices such as overload relays.

Ferraz Shawmut has been a leader in circuit protection for industry and the electrical market for more than 100 years. With a complete line of current-limiting fuses and accessories, Ferraz Shawmut prides itself on delivering innovative, problem-solving products like the Surge-Trap® SPD, Thermally Protected Metal Oxide Varistor (TPMOV®), the FSLBS Load Break Switch, the SmartSpot® open-fuse indicator, Amp-Trap 2000® fuses, and UltraSafe(TM) fuse holders. Two of the company's latest innovations are its new line of Amp-Trap® High-Speed Class J (HSJ) fuses, engineered specifically for the protection of today's sensitive electronic motor controllers, and the industry's first line of Finger-Safe Power Distribution Blocks (FSPDBs), delivering the ultimate in safety and ease-of-use when making power connections in electrical panels.
