FAQ

The gL/gG designation indicates a general-purpose fuse characteristic according to older (gL) and newer (gG) standards. It is designed to protect against both overload (slow-blow) and short-circuit (fast-blow) conditions, making it suitable for protecting cables and general equipment.

Yes, absolutely. A fuse's voltage rating is the maximum voltage it can safely interrupt. Using a 500V fuse in a 400V system is perfectly safe and common practice, as it provides a safety margin.

The breaking capacity, or interrupting rating, of 120kA (120,000 Amperes) is the maximum prospective short-circuit current that the fuse can safely clear without rupturing. This high rating is crucial for industrial systems where fault currents can be extremely high, ensuring personnel and equipment safety.
