OptiFuse is an American manufacturer specialising in producing innovative circuit protection solutions. It offers an extensive product range encompassing fuses and circuit breakers, plus fuse accessories, such as blocks and clips.
The CBW57 series of thermal fuses are particularly worth your attention. They are offered in two rated voltage ranges, i.e. from 32 V to 50 V DCand from 125 V to 250 V AC. A broad rated current range, i.e. from 3 A to 15 A, is an additional advantage. The maximum voltage and current values are also a strong point of these products. They amount to, respectively, 1.5 kV AC and 1 kA, thanks to which the fuses meet the requirements of applications in the field of power engineering (e.g. renewable power sources, energy storage banks) or industry. The CBW57 fuses can also be used for additional circuit protection. For instance, they are compliant with the American UL1077 standards for additional protection, and they are often used in marine equipment or camping vans.
The dimensions of the CBW57 fuses available from TME are 29.5 x 14.6 x 22.7 mm. Their operating temperature range is from -10°C to 60°C. The fuses included in the series described here come with a manual reset function.
