Fuse Specifications
This pack contains twenty cylindrical ceramic fuses rated at 40 amps with a gG operating class. They are built to a 14 by 51 millimetre form factor and carry a dual voltage rating of 500 volts AC and 690 volts AC. The breaking capacity is listed as 100 kiloamps at 500 volts and 50 kiloamps at 690 volts.
Target Applications
These fuses suit industrial and commercial circuits that need general-purpose conductor protection at the stated voltage and current levels. They are not intended for motor-start circuits requiring aM characteristics or for systems that demand a different body diameter or length.
Critical Selection Parameter
The 40 amp gG rating at 500/690 volts AC in a 14x51mm ceramic body is the single specification that determines whether this fuse matches the circuit design. Verify the required current rating, voltage class and physical dimensions against your equipment documentation before fitting.

Questions about this item
When will the 40A gG fuse element need replacement?
The ceramic fuse element is single-use; it must be replaced after any over-current event that causes it to blow.
What interrupts the 500/690V circuit first during a sustained overload?
The 40A gG rating opens the circuit once current exceeds 40 amps for the time defined by the gG curve.
How much heat does the 14x51mm ceramic body dissipate during continuous 40A operation?
The ceramic tube is designed to run at its rated 40A without excessive temperature rise under normal ventilation.
