Inverter and converter circuits
This fuse is not suitable for general-purpose residential electrical circuits or applications where a gG (general purpose) characteristic is required for cable protection. It is specifically designed for semiconductor protection and may not provide the necessary time-delay characteristics required for motor starting or high-inrush current applications.
Key specifications
Rated current: 400A
Rated voltage: 500V
Characteristic: aR (semiconductor protection)
Size: NH00
To install the fuse, ensure the power supply is completely disconnected and the circuit is de-energized. Insert the fuse link into a compatible NH00 fuse base using an appropriate insulated fuse handle or extraction tool. Verify that the fuse is seated firmly and that all electrical connections are tightened to the manufacturer's specified torque settings before restoring power.
What to consider before purchase
Verify that the 400A rating matches your circuit requirements
Ensure the fuse base is compatible with the NH00 size
Confirm that the aR characteristic is appropriate for your specific equipment
Always replace fuses with the exact same type and rating to maintain the safety and integrity of your electrical system. Regularly inspect the fuse base for signs of heat damage or oxidation to ensure optimal performance.
