FSC Porcelain Type Standard and Loadbreak Fuse Cutout

FSC Porcelain Type Standard and Loadbreak Fuse Cutout

Drop out fuse cutout can is for use of outdoor medium voltage and high voltage alternative current system,which mainly protects transformer and distribution power line from short circuit and overload. It drops down in base while fuse link melted.Standard type fuse cutout can function like overhead disconnect switch.A 300 amp disconnect blade is also available for this purpose.
Products are completely in accordance with IEC60282-2, ANSI C37.41, ANSI C37.42 standard.

Overview

FSC porcelain fuse cutout series

Standard and Loadbreak Protection for Overhead Distribution

The FSC porcelain drop out fuse cutout series is designed for outdoor AC distribution systems, where the fuse link operates under overload or short-circuit conditions and the holder drops to provide a visible indication.

The published FSC range covers 10–36 kV with 100 A and 200 A rated-current options. Standard and FSC-( )F loadbreak executions are listed in the supplier source.

Rated-voltage range: 10–36 kV
Rated-current options: 100 A / 200 A
Published frequency: 48–62 Hz
Executions: Standard / loadbreak

The source lists compliance with IEC 60282-2, ANSI C37.41 and ANSI C37.42. Confirm the required edition and project acceptance documents before ordering.

Construction and operation

Components That Support Switching and Interruption

The supplier source describes the conductive path, fuse-tube construction and selectable hardware. Match each option to the utility specification rather than treating every feature as standard.

Fuse tube and holder

The fuse tube uses fiberglass with a synthetic arc-extinguishing liner and a UV-resistant coating. The holder is described as exchangeable.

Conductive contacts

The top contact is a silver-coated red-copper strip, while the hinge uses bronze and silver-plated copper-alloy contacts.

Arc-shortening option

A silver-plated copper arc-shortening rod is available; when this option is used, the source requires a fuse link with a removable button head.

Mounting and hardware

Choose NEMA A, NEMA B or an extended galvanized-steel mounting bracket for the project crossarm. Stainless-steel hood, loadbreak hooks and hardware are listed as corrosion-resistance options.

The supplier source states a mechanical life of more than 3,000 opening and closing operations. Treat this as supplier-stated data until the applicable test method and report are confirmed.

The original specification table contains an unlabeled 300 A column. Its meaning is not published, so confirm whether it refers to the optional disconnect blade before using it in a purchase specification.

Selection checklist

Define the Configuration Before Quotation

Match the system voltage. Start with FSC-1, FSC-12, FSC-18 or the FSC-21/22/23 group using the published voltage range.
Pair current and interrupting duty. Select the 100 A or 200 A row and verify that the corresponding breaking-current value suits the protection study.
Choose standard or loadbreak. The standard type is described as usable for overhead disconnecting service; FSC-( )F identifies the porcelain loadbreak execution.
Confirm mounting and materials. State the bracket type, crossarm arrangement and required corrosion-resistant hardware.
Confirm the fuse-link arrangement. If an arc-shortening rod is selected, specify the removable button-head fuse link required by the source.

Configuration boundaries

Items to Confirm With the Supplier

Porcelain or polymer support

The source also describes a silicone-rubber polymer support that has passed a 1,000-hour salt-spray test. Because this page is for the porcelain series, confirm the required support material before quotation.

Disconnect-blade rating

A 300 A disconnect blade is listed as an option for disconnecting service. Confirm its relationship to the unlabeled 300 A table column and the selected standard or loadbreak execution.

Frequently asked questions

FSC Porcelain Fuse Cutout FAQ

What voltage range does the FSC porcelain series cover?

The published table covers 10–36 kV across FSC-1, FSC-12, FSC-18, FSC-21, FSC-22 and FSC-23. Use the individual row to confirm current, breaking duty and insulation values.

What is the difference between the standard and loadbreak versions?

The source describes the standard type as usable for overhead disconnecting service and identifies FSC-( )F as the porcelain loadbreak version. Confirm the blade and hook arrangement for the selected model.

Which fuse link is required with the arc-shortening rod?

The supplier source requires a fuse link with a removable button head when the arc-shortening rod is used.

What should be included in a quote request?

Confirm model, execution, bracket, fuse-link arrangement, quantity and destination market in the quote request. Include the applicable standard edition and project test-document requirements.
