Suitable for

• Industrial electrical distribution boards
• Commercial building power systems
• Protection of motor circuits and control panels
• General electrical circuit safeguarding

When it may not be suitable

This fuse is not intended for use in applications requiring specialized protection characteristics, such as fast-acting fuses for sensitive electronic components or aR fuses for semiconductor protection. It should not be installed in systems where the rated voltage or current requirements exceed the specific technical limits of the device.

Key specifications

• Dimensions: 22x58 mm
• Rated current: 40A
• Fuse class: gG
• Application: Industrial and commercial electrical protection

How to use

The fuse should be inserted into a compatible 22x58 mm cylindrical fuse holder. Ensure that the power supply is disconnected before installation or replacement to prevent electrical shock. Once placed in the holder, ensure the fuse is seated firmly to maintain proper electrical contact. The device is designed for maintenance-free operation, but it should be inspected periodically if the system has been subjected to significant electrical faults.

What to consider before purchase

• Verify that the fuse holder is compatible with the 22x58 mm size
• Ensure the 40A rating matches the requirements of the circuit being protected
• Confirm that the gG class is appropriate for the intended application

Usage recommendations

Always replace a blown fuse with one of the exact same type, size, and current rating to ensure continued safety and compliance with electrical standards. Never attempt to bypass or repair a blown fuse.
