• General electrical equipment protection

This fuse may not be suitable for applications requiring specific fast-acting characteristics for highly sensitive electronic components, as it is designed with a gG curve for general-purpose protection. It is also not intended for use in circuits exceeding its rated voltage of 690V AC or current rating of 4A.

Key specifications

• Dimensions: 14x51mm
• Rated current: 4A
• Rated voltage: 690V AC
• Characteristic: gG
• Quantity per pack: 1 piece

To install the fuse, ensure the power supply is completely disconnected from the circuit. Insert the cylindrical fuse link into a compatible 14x51mm fuse holder or base, ensuring a secure and firm fit. Once installed, verify that the fuse is properly seated before restoring power to the system. Always handle the component with care to avoid physical damage to the ceramic body or contact caps.

What to consider before purchase

• Verify that the 4A current rating matches your circuit requirements.
• Ensure the fuse holder is compatible with the 14x51mm form factor.
• Check that the system voltage does not exceed 690V AC.

Always replace a blown fuse with one of the exact same type, rating, and physical dimensions to ensure continued safety and compliance with electrical standards.
