MRBF battery terminal fuse designed for 58V DC high-current circuit protection. CZY-FS14 is the non-waterproof version of this MRBF series and supports a 30A–500A current range for compatible battery and power distribution applications.
B2B inquiries are normally answered within one business day.
The CZY-FS14 MRBF battery terminal fuse is a compact high-current fuse designed for 58V DC battery and power distribution circuits.
This product is the non-waterproof version of Cozy Electronics’ MRBF fuse series and is available in a confirmed 30A–500A current range. The compact MRBF format allows circuit protection to be positioned close to the battery or main power connection in compatible electrical systems.
CZY-FS14 is suitable for applications that require an MRBF battery terminal fuse but do not require the additional environmental protection provided by the waterproof version.

The CZY-FS14 MRBF battery terminal fuse can be used in compatible high-current DC electrical systems.
Typical applications include:
The appropriate current rating should always be selected according to the actual electrical system and circuit protection requirements.
MRBF fuses are designed to provide compact high-current circuit protection close to the battery or main power source.
The CZY-FS14 uses the MRBF battery terminal fuse format and is intended for installations where this specific fuse structure is required.
When selecting an MRBF fuse, buyers should confirm:
A fuse should not be selected only because its current rating appears similar to another product.
CZY-FS14 supports a confirmed current range of:
30A–500A
The exact fuse rating should be selected according to the original circuit design, wiring capacity and connected equipment.
Do not increase the fuse rating simply because a higher-current fuse physically fits the installation.
Cozy Electronics offers two versions of this MRBF fuse series:
Designed for applications where additional environmental protection around the fuse assembly is required.
The standard non-waterproof version, intended for compatible installations where additional waterproof protection is not required.
Both versions share the same confirmed electrical specifications:
The correct version should be selected according to the installation environment and system requirements.
Make sure the electrical system is designed for an MRBF battery terminal fuse.
Select the fuse rating specified for the intended circuit.
The current rating should be based on the circuit design rather than fuse appearance or color.
CZY-FS14 is designed for 58V DC electrical systems.
Confirm that the fuse structure matches the intended battery terminal, fuse holder or power distribution arrangement.
CZY-FS14 is the non-waterproof version.
If additional environmental protection is required, the waterproof CZY-FS13 version should be considered instead.
Battery-side overcurrent protection is an important part of high-current DC electrical system design.
Placing a compatible fuse near the battery or main power connection allows the protection device to interrupt the circuit when an overcurrent condition exceeds the intended fuse characteristics.
The fuse rating, cable capacity and electrical load should therefore be considered together when designing or replacing a battery protection circuit.
Cozy Electronics supports OEM / ODM cooperation for automotive and DC circuit protection projects.
Product configuration, current-rating requirements and packaging requirements can be discussed according to the customer’s project.
An MRBF battery terminal fuse is a compact high-current fuse designed for installation in compatible battery and DC power circuits, typically close to the main power source.
CZY-FS14 is rated for 58V DC.
The confirmed current range is 30A–500A.
No. CZY-FS14 is the non-waterproof version of this MRBF fuse series.
For applications requiring additional environmental protection, the CZY-FS13 waterproof version is available.
Both versions have the same confirmed electrical specifications:
The difference is the product configuration:
No. Fuse color should not be used as the only method of identifying current rating. The required rating should be confirmed from the circuit specification and product marking.
Cozy Electronics supplies MRBF fuses and other battery circuit protection components for automotive, distribution and customized electrical projects.
