2. M.V. Fuses & Accessories used for:
Motor and motor controller protection
Transformer protection
Distribution system protection
Capacitor protection
During this presentation we will review the Ferraz Shawmut medium voltage fuses and accessories product line. For the purpose of this presentation and since medium voltage fuses are designed for specific applications, we will categorize our product line for the type of application they are used for. For each type of application, we will review the products we offer, where they are used and who our competitors are.

3. Common fuse terms and definitions
Backup
Current-Limiting Fuse Types
General Purpose
Full Range
Per ANSI and IEEE standards, there are three different types of current-limiting fuses: Backup fuses, General Purpose fuses and Full Range fuses. The three fuse types differ in the “low” melting current they are designed to interrupt. Their characteristics define the type of applications the fuses can be used for.

A480R6R-1
For the protection of medium voltage motor and motor control centers, Ferraz Shawmut Amp trap R-Rated fuses make up the most extensive line of backup current-limiting fuses in the industry. Most fuses of this line are UL Recognized. An R-rated fuse must melt in 15 to 35 seconds at a value of current equal to 100 times the R rating.
The R-Rated Amp-Trap line ranges from 2.4 kilovolt to 15.5 kilovolt; with R-ratings from 1R to 57X. We offer three mounting configurations as shown here: Bolted, DIN-style and Ferrule.
Our part numbers are easy to decipher, for example the:
A072B3D0R0-48X fuse is 7.2 kilovolt, bolted, with 3 barrels and rated 48X
The A480R6R-1 fuse is 4.8 kilovolt and rated 6R.

5. Motor and Motor Controller Protection 9F line
9F60 series, EJ-2 type
R-Rated
Backup motor starter CL fuses
UL Recognized up to 24R
2.54 kV – 2R to 24R
5.08 kV – 2R to 36R
In addition to the Amp-Trap line for the protection of medium voltage motor and motor control centers, we have the 9F60 series Type EJ-2. These R-rated back-up current-limiting fuses are UL recognized for ratings up to 24R. Two voltages are available; 2.54 kilovolt and 5.08 kilovolt, rated from 2R to 36R. While the size and ratings available seem redundant with the Amp-Trap line, the element designs are very different, resulting in distinct electrical characteristics. You’ll find many of the 9F60 series EJ-2 type fuses in the GE motor control equipment.
The part numbering system for the EJ-2 is very close to be meaningless. For details, you will need to refer to the catalog.
Ferraz Shawmut is the market leader for R-Rated fuses with many OEMs such as Rockwell, Square-D, Benshaw, GE, Toshiba and ABB specifying our products in their equipment.

6. Motor and Motor Controller Protection
Applications:
Across the line starter
Soft starter
Drive
Motor Control Center
Fuse purpose:
Back up fuse
Short circuit protection
Fuse characteristics:
Handle the motor Inrush
R-Rated fuses are used for short circuit protection for the following type of motor and motor controller equipment:
Across the line starter
Soft starter
Drive
Motor Control Center
The purpose of the R-Rated fuses is to act as a back-up fuse and give high fault current protection. Since they do not provide overload protection, another protective device must be properly coordinated with the fuse to fulfill this function.
One of the most important characteristics for the motor protection fuses is that they must handle the motor inrush current during start-up time.

For the protection of transformers and distribution systems, Ferraz Shawmut offers general purpose fuses from our Amp-Trap product line, which meet E-rated requirements:
Please remember that an E-rated fuse is defined as follows, “When rated 100E and below, the fuse must melt in 300 seconds at 200% to 240% of its E-Rating. Above 100E, the fuse shall melt in 600 seconds at 220% to 264% of its E-Rating. Further information on E-rated fuses, can be found in our “Definitions and Introductions to IEEE/ANSI Standards” training module.
Our general purpose Amp-Trap line is for indoor usage only. Most of our fuses are UL listed. We offer voltage ratings from 5.0 kilovolt up to 15.5 kilovolt with ratings from 10E up to 1200E. For installation purposes, we offer three mounting configurations: Clip Lock style (or CL14) as shown on the left picture, Ferrule as shown in the center and Bolted as shown on the on the right.
Part numbers are easy to decode: An A825X30E-1, is a kilovolt fuse rated 30E.
An A072B2D0R0-350E is a 7.2 kilovolt, Bolted, made with 2 barrels and rated 350E.

14. Transformer and distribution system protection
Applications:
Potential transformers for metering application
Fuse purpose:
Short circuit protection
Fuse characteristics:
Handle the transformer magnetizing inrush when energized.
Measuring or monitoring certain electrical characteristics in a medium voltage circuit can only be done after stepping down the voltage. This is done using a potential transformer or a control potential transformer. The PT fuses are used for the protection of these transformers. The purpose of the fuse is to provide short circuit protection on the primary while being able to handle the high magnetizing inrush current when the transformer is energized.

Still part of our 9F61 series are the fuse disconnect switches. The type EK-3 on the left is for indoor usage and the type EKO-3 on the right is for outdoors. These fuse disconnect switches are a practical system to remove and install the fuse. While open it keeps the load safely disconnected from the source. It is important to note that these disconnecting switches are not load-breaking devices, therefore the circuit must be open prior to the fuse disconnection.
All fuse disconnecting switches and fuse supports come ready to use, all the user needs to supply is the fuse.

24. Why our medium voltage product line is successful
Broad product line
High service level, with many of items in stock
Medium voltage equipment is the most economical solution
It uses less power than low voltage
Requires less copper
Motor control centers reduce stress on the equipment and
electrical system.
Reduces energy consumption
Medium voltage semiconductors can support these applications
Medium voltage breakers are very expensive.
The strength of Ferraz Shawmut’s medium voltage fuse line is attributed to:
The breadth of our medium voltage product line and a high level of service with items in stock.
In addition, the need for medium voltage equipment is growing as compared to low voltage, because often it is the most economical solution:
A medium voltage system use less power than a low voltage system.
Medium voltage equipment requires less copper.
Medium voltage motor control centers reduce stress on the equipment and electrical system, consequently reducing maintenance and repair costs
The use of medium voltage equipment helps reduce energy consumption
Medium voltage semiconductors can support these applications as they are now able to work at higher voltages and can handle higher current values
Medium voltage breakers are very expensive as compared to fuses alone or fuse/contactor combination.

25. The Value of Having an Inventory of Spare Parts
Downtime on one piece of equipment is expensive.
Having spare parts is a necessity
Finally it is important to mention the value of having an inventory of spare parts. The downtime on medium voltage equipment is expensive because it typically powers all sections of a building or a few pieces of equipment. In order to reduce downtown on medium voltage equipment, having an inventory of spare parts should not be considered a luxury but a necessity.
