B2B inquiries are normally answered within one business day.
The CZY-FS13 waterproof MRBF fuse is a compact battery terminal fuse designed for 58V DC circuit protection in compatible high-current electrical systems.
MRBF fuses are designed for installation close to the battery or main power connection, helping provide circuit protection at the power source. CZY-FS13 is the waterproof version of this MRBF fuse series and is available in a broad 30A–500A current range for different battery and power distribution requirements.
Its compact battery-terminal format makes it suitable for applications where space-efficient high-current circuit protection is required near the power source.

The CZY-FS13 waterproof MRBF fuse is suitable for electrical systems requiring compact battery-side circuit protection.
Typical applications can include:
The exact fuse rating should always be selected according to the electrical system and circuit protection requirements.
CZY-FS13 is the waterproof version of the MRBF battery terminal fuse series.
This version is intended for applications where additional protection against environmental exposure is required around the fuse assembly.
The waterproof description does not imply a specific IP rating. No IP67 or IP68 classification should be assumed unless supported by a corresponding test report.
For applications with defined environmental protection requirements, the installation conditions and required protection level should be confirmed before product selection.
Installing circuit protection close to the battery can help protect downstream wiring and electrical equipment when an overcurrent condition occurs.
The compact MRBF format is particularly useful when the fuse needs to be positioned near the main battery connection while keeping the power distribution layout relatively compact.
When selecting the fuse, buyers should confirm:
CZY-FS13 supports a confirmed current range of:
30A–500A
The specific fuse rating should be selected according to the original circuit design, conductor capacity and equipment requirements.
Do not select a higher-current fuse simply because it physically fits the installation.
CZY-FS13 is designed for 58V DC systems.
Choose the required fuse rating according to the electrical design rather than body appearance or color.
Make sure the application is designed for an MRBF battery terminal fuse.
The fuse and battery-terminal connection must be mechanically compatible with the intended installation.
CZY-FS13 is the waterproof version. If the application requires a specific IP protection level, that requirement should be confirmed separately.
Cozy Electronics offers both waterproof and non-waterproof MRBF fuse versions.
The two versions share the same confirmed electrical specification:
The main distinction is the product version and environmental protection configuration.
For applications where additional environmental protection is preferred, CZY-FS13 is the appropriate version. For installations where this protection is not required, the non-waterproof version can be selected according to the system design.
Cozy Electronics supports OEM / ODM cooperation for automotive and battery circuit protection projects.
Customization requirements can be discussed according to the customer’s electrical system, product configuration and project requirements.
An MRBF fuse is a compact battery terminal fuse designed for high-current DC circuit protection near the battery or main power connection.
CZY-FS13 is rated for 58V DC.
The confirmed current range is 30A–500A.
Yes. CZY-FS13 is the waterproof version of this MRBF fuse series. However, no specific IP rating is claimed without a corresponding test report.
The confirmed electrical specifications are the same: 58V DC with a 30A–500A current range. The difference is the waterproof versus non-waterproof product configuration.
MRBF fuses are used in compatible battery and high-current DC power circuits, typically close to the battery or main power distribution point.
Cozy Electronics supplies MRBF fuses and other automotive circuit protection components for battery, vehicle and DC power distribution applications.
