What is the interrupting rating of a Class T fuse?

Class T fuses generally have high interrupting capacities, often ranging from 10,000 to 200,000 amperes. This means they can safely interrupt fault currents of varying magnitudes without causing damage to the electrical system or posing a safety hazard. It’s essential to select a Class T fuse with an interrupting rating that meets or exceeds the maximum fault current that could occur in the system to ensure proper protection and safety.

How do I select the correct Class T fuse for my application?

Consider factors such as current and voltage ratings, time-delay requirements, interrupting capacity, and physical dimensions to ensure compatibility and optimal protection.

Can Class T fuses be used in both AC and DC circuits?

Yes, Class T fuses can typically be used in both AC and DC circuits, but it’s essential to verify compatibility and select the appropriate fuse for each application.
