Frequently Asked Questions
What does the gTr characteristic mean for this fuse?
The gTr characteristic indicates a time-delay fuse suitable for protecting transformers and motors, allowing brief overloads without blowing, but providing fast interruption under short-circuit conditions.
Can this fuse be used in DC circuits?
No, this fuse is designed specifically for AC applications up to 400VAC and should not be used in DC circuits.
How does the centre indicator work?
The centre indicator visually shows the fuse status by changing appearance when the fuse element has operated, enabling quick identification of blown fuses without disassembly.
Are isolated tags necessary?
Isolated tags improve safety by reducing the risk of accidental contact with live terminals during installation or maintenance, making them highly recommended in industrial environments.
