China Supplier of Forkbolt Automotive Fuses

Forkbolt auto fuses (also known as forkbolt fuses) are automotive fuses designed for high-current circuits. Their core parameters and characteristics are as follows:
аз. Core Parameters
‌Current Specifications‌
‌Small Forkbolt Type‌: 30A-150A (typical model ANS-B)
‌Large Forkbolt Type‌: 40A-800A (some models support 500A and above)
‌Voltage Rating‌
Compatible with 32V or 125V DC systems
‌Physical Dimensions‌
Typical dimensions of small size: 12×41×8.5mm (with D5.5mm mounting holes)

II. Structural Characteristics
‌Connection Method‌
Bolt-on fastening increases the contact area by 300% compared to blade-type fuses, reducing the risk of loose connections.
‌Fusing Characteristics‌
Most fuses are slow-blow, capable of withstanding short-duration surges of up to 7 times the rated current (such as those used for motor starting).
‌Material‌
Housing: PBT flame-retardant material
Диригент: Copper alloy with gold plating/zinc alloy, strong oxidation resistance

III. Typical Application Scenarios
Heavy-Duty Vehicles: Truck and Bus Starter Motors (over 300A)
Modified Circuits: High-Power Audio Systems, Inverters (100-200А)
New Energy Vehicles: High-Voltage Power Distribution Systems (125V/150A)

IV. Selection Considerations
Matching Principles
Must be compatible with the original vehicle fuse holder (e.g., ANS-200/300).
Installation Requirements
Use a torque wrench to tighten the bolts (5-8 N·m recommended).
Replacement Risks
Misuse of blade-type fuses may result in poor contact and fire.

Забележка: When replacing, consult the vehicle maintenance manual first. Do not use fuses that exceed the specified fuse specification.
