The "S" and "W" markings on a 250V T800mA fuse typically indicate the type and characteristics of the fuse. The "S" stands for "slow-blow" or "time-delay," meaning the fuse can withstand temporary overloads without blowing, while "W" may signify a specific manufacturer’s designation or a particular application. Together, they help identify the fuse's intended use and its protection characteristics in electrical circuits. Always refer to the manufacturer’s documentation for precise definitions.

What do numbers mean in t630mA 250v stand for?

In the designation "t630mA 250V," the "t" indicates that the component is a time-delay fuse. The "630mA" specifies the current rating, meaning the fuse will allow a maximum current of 630 milliamperes before it blows. The "250V" indicates the maximum voltage rating, meaning the fuse can safely operate at voltages up to 250 volts. Together, these specifications define the fuse's electrical characteristics and its suitable application in circuits.


Can you substitute 6a 250v with 10a 250v?

Yes, you can substitute a 6A 250V component with a 10A 250V component as long as the voltage rating is the same and the application does not exceed the 10A current rating. The higher-rated component can handle more current, making it a suitable replacement. However, ensure that other specifications, such as physical size and connection compatibility, are also met. Always consult relevant guidelines to ensure safety and compliance.


What does 312 mean on a fuse?

The 312 designation means that it is a 312 series fuse made by a company called Littelfuse. This is a series of fast acting, glass cartridge fuse. Knowing the series allows you to look up the exact specifications for the fuse at the company's website. The fuse would have a rating impressed into one if the steel caps that looks like: 250V 312 5A Indicating it is a 250 Volt, 5A fuse, and is a Littelfuse 312 series, which implies fast acting, specific performance specifications and its size (31.75+/- 1.12mm x 6.25 +/- 0.3mm).


What does F stand for in a fuse labeled F6A 250V?

Typically the "F" stands for "Fast Blow" or "Fast Acting". A "T", as in T6A, would mean "Time Delay" or Slow-Blow. So, an F6A 250 is a Fast Acting (Fast Blow) 6 Amp 250 Volt Fuse.


What does a 250v - 660w rating mean on a bathroom fixture?

A 250V - 660W rating on a bathroom fixture means that it is designed to operate with a maximum voltage of 250 volts and draw a maximum power of 660 watts. This rating helps ensure that the fixture is safely connected to the appropriate electrical supply in your home.
