FAQ What does the gL/gG characteristic mean for this fuse?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. Can this 500V fuse be used in a 400V three-phase system?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. What is the significance of the 120kA breaking capacity?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. profideals is not an authorized distributor, reseller or representative of the products featured on this website.
