This fuse may not be suitable for applications requiring standard time-delay characteristics or for circuits operating at voltages exceeding 690VAC. It is specifically optimized for semiconductor protection and may not provide the intended results in general-purpose residential or low-voltage household wiring applications.

Key specifications

• Rated voltage: 690VAC
• Rated current: 8A
• Fuse size: 10x38 mm
• Characteristic: gR (full-range semiconductor protection)
• Type: Cylindrical ultra-fast

To use the Mersen Z1014575, ensure that the power supply to the circuit is completely disconnected before installation. Insert the fuse into a compatible 10x38 mm fuse holder or disconnect switch, ensuring a secure fit to prevent overheating due to poor contact. Once installed, verify that the circuit is properly closed and that the fuse is correctly seated before restoring power to the system.

What to consider before purchase

• Verify that the 8A current rating matches your circuit requirements
• Ensure the 690VAC voltage rating is compatible with your application
• Confirm that the 10x38 mm physical size fits your existing fuse block
• Check that the gR characteristic is appropriate for your specific semiconductor protection needs

Always replace the fuse with one of the exact same type and rating to maintain the safety and performance of your electrical equipment. Regularly inspect fuse holders for signs of oxidation or wear to ensure optimal electrical conductivity.
