Regular (APR / ATC / ATO / ATS) blade-type fuses, also known as standard, were developed in 1976 as ATO by Littelfuse [2] for low voltage use in motor vehicles. Bussmann makes the ATC [3] that also complies with the same ISO 8820-3 and SAE J1284 standards. OptiFuse, a newer entrant in the market, makes regular (APR / ATC / ATO) fuses that meet ...
Fuse packages may include a rejection feature such as a pin, slot, or tab, which prevents interchange of otherwise similar appearing fuses. For example, fuse holders for North American class RK fuses have a pin that prevents installation of similar-appearing class H fuses, which have a much lower breaking capacity and a solid blade terminal ...
Japanese-style ATC cab signalling indicator. Automatic train control (ATC) is a general class of train protection systems for railways that involves a speed control mechanism in response to external inputs. For example, a system could effect an emergency brake application if the driver does not react to a signal at danger.
On a 3-phase circuit, a recloser is more beneficial than three separate fuse cutouts. For example, on a wye to delta conversion, when cutouts are used on the wye side and only 1 out of 3 of the cutout fuses open, some customers on the delta side have a low voltage condition, due to voltage transfer through the transformer windings. Low voltage ...
Breaking capacity or interrupting rating [1] [2] is the current that a fuse, circuit breaker, or other electrical apparatus is able to interrupt without being destroyed or causing an electric arc with unacceptable duration.
