Country of Origin Made in Denmark. CO2 Impact By purchasing this pre-owned fuse, you are contributing to a circular economy and avoiding approximately 60 kg of CO2 emissions associated with the production of a new unit. This is comparable to the emissions of a 300 km car journey. Availability This item is in stock and ready for immediate dispatch. Order now from profideals for expert support and fast delivery. FAQ Question?What does the ‘aR’ rating on this Bussmann 170M6419 fuse signify? Answer:The ‘aR’ class designation indicates a partial-range, high-speed fuse. It is specifically designed for short-circuit protection of power semiconductors like diodes, thyristors, and IGBTs. It is not intended for overload protection. Question?Can I replace a standard ‘gG’ fuse with this ‘aR’ fuse? Answer:No, this is not recommended. A ‘gG’ fuse provides full-range protection (both overload and short-circuit), while this ‘aR’ fuse only protects against short-circuits. Using an ‘aR’ fuse in a ‘gG’ application would leave the circuit unprotected against overloads. Question?What is the function of the red dot indicator on the fuse body? Answer:The red dot is a visual trip indicator. If the fuse operates (blows) due to a short-circuit, a small pin will pop out from this indicator. This provides an immediate visual confirmation that the fuse needs to be replaced. profideals is not an authorized distributor, reseller or representative of the products featured on this website.
