G&W Electric’s encapsulated fuses provide the current limiting protection of an X-Limiter™ full range fuse within a completely sealed, rugged epoxy housing designed for submersible applications. No derating of the fuse is required. Terminal connections consist of IEEE 200A bushing wells, permitting the use of 200A dead break and load break bushing inserts and elbows. The small size and ease of installation of the fuses make them ideal for padmount, vault or subsurface applications where space is at a premium. Optional stainless steel mounting brackets with integral parking stands allow the fuses to be mounted easily with a minimal support structure.
Features and Benefits
Ease of Installation - The economical, one piece epoxy encapsulated fuse can be easily installed and removed. There is no assembly of components or special tools required. Hold down straps permit fuse removal without removing the mounting bracket
G&W Electric Encapsulated Fuses - Utilize rugged time-proven EPOX technology comprised of Vantico Araldite® 229 polymer to assure a void-free, extremely durable system impervious to environmental contamination
Tested Reliability - Epox fuses are designed and tested to applicable sections of IEEE C37.40, IEEE C37.41, IEEE C37.47 and IEEE 386 standards
Customizing Capability - G&W Electric specializes in custom solutions to meet the ever changing needs of it’s customers. Contact your G&W Electric representative with specific application requirements
Fuses use Cooper X-Limiter type - 8.3kV and 15.5kV rated fuses. A link is provided under the "Resources" section to take you to the TCC curves located on the Cooper web site
2-Position Design
The 2-position encapsulated fuse is G&W Electric's most compact design. The small space required for mounting makes this design ideal for vault, transformer, and padmount installations. The optional 304 stainless steel mounting bracket can be mounted horizontal or vertically. Integral parking stands can be rotated to match the installation. Hold down straps allow fuse replacement without removing the bracket and also provide direct surface mounting of the fuse for padmount installations.
3-Position Design
The 3-position encapsulated fuse provides a feed thru bushing on the line side of the fuse in addition to a single bushing on the load side. The feed thru bushing can also be used to install an arrestor or insulating plug. The optional 304 stainless steel mounting bracket can be mounted horizontal or vertically. Integral parking stands can be rotated to match the installation. Hold down straps allow fuse replacement without removing the bracket and also provide direct surface mounting of the fuse for padmount installations.
