The CZY-FS12 Long-Body JCASE Fuse is an automotive cartridge fuse designed for 32V vehicle electrical systems.
This version uses a long-body JCASE structure with extended terminals, providing a different physical format from short-body and other JCASE fuse configurations. It is intended for compatible automotive fuse boxes and electrical assemblies that require this specific JCASE connection structure.
CZY-FS12 is available in current ratings from 20A to 120A, supporting a range of automotive circuit protection and power distribution applications.
Because JCASE fuses are available in different body and terminal configurations, the physical fuse format should always be confirmed together with the current rating and voltage requirement before replacement or bulk sourcing.

The CZY-FS12 long-body JCASE fuse is designed for automotive electrical systems that require a compatible long-body JCASE format.
Typical applications include:
The actual fuse requirement should always be checked against the vehicle, fuse box or equipment specification before installation.
The defining feature of CZY-FS12 is its long-body JCASE structure.
Compared with short-body JCASE versions, this fuse uses a longer body and extended terminal configuration. This difference in physical structure means that two JCASE fuses with the same current rating should not automatically be considered interchangeable.
For replacement and sourcing applications, buyers should confirm:
Physical compatibility is especially important when different JCASE fuse styles are used within the same automotive electrical system.
CZY-FS12 is available in the following confirmed current ratings:
20A / 30A / 40A / 50A / 60A / 70A / 80A / 90A / 100A / 120A
The required fuse rating should be selected according to the original vehicle or circuit specification.
Do not determine the fuse rating from body color alone.
Make sure the application requires the long-body JCASE fuse rather than a short-body, standard or low-profile JCASE format.
Use the current rating specified for the circuit. A higher-current fuse should not be substituted simply because the physical size appears compatible.
CZY-FS12 is designed for 32V DC automotive systems.
The body and terminal configuration should match the intended fuse box or electrical assembly.
CZY-FS12 and CZY-FS11 belong to the JCASE fuse family but use different physical formats.
The two versions should be identified by their body and terminal structure rather than by current rating alone.
When replacing an existing fuse, compare the original component carefully before selecting the replacement.

A long-body JCASE fuse is an automotive cartridge fuse with an extended body and terminal configuration designed for compatible vehicle fuse boxes and electrical circuits.
CZY-FS12 is rated for 32V DC automotive electrical systems.
The confirmed current ratings are:
20A, 30A, 40A, 50A, 60A, 70A, 80A, 90A, 100A and 120A.
No. Both belong to the JCASE fuse family, but their physical body and terminal configurations are different. The correct format should be confirmed before replacement.
Fuse color should not be used as the only method of identifying the current rating. Confirm the product marking and circuit specification.
