A resettable fuse or polymeric positive temperature coefficient device (PPTC) is a passive electronic component used to protect against overcurrent faults in electronic circuits. The device is also known as a multifuse or polyfuse or polyswitch .
In 1992, Black & Decker began a major effort to rebrand its professional quality and high-end power tools to DeWalt. In 1994, DeWalt took over the German woodworking power tool producer ELU, and used ELU's technology to expand their tool line. As of 2001, they manufacture and sell more than 200 hand power tools and 800 accessories. [2]
In electrical distribution, a fuse cutout or cut-out fuse (often referred to as a cutout) is a combination of a fuse and a switch, used in primary overhead feeder lines and taps to protect distribution transformers from current surges and overloads. An overcurrent caused by a fault in the transformer or customer circuit will cause the fuse to ...
A 115 kV high-voltage fuse in a substation near a hydroelectric power plant Older medium-voltage fuse for a 20 kV network. These type of fuses may have an impact pin to operate a switch mechanism, so that all three phases are interrupted if any one fuse blows. High-power fuse means that these fuses
The AC output voltage of a power inverter is often regulated to be the same as the grid line voltage, typically 120 or 240 VAC at the distribution level, even when there are changes in the load that the inverter is driving. This allows the inverter to power numerous devices designed for standard line power.
A distribution board (also known as panelboard, circuit breaker panel, breaker panel, electric panel, fuse box or DB box) is a component of an electricity supply system that divides an electrical power feed into subsidiary circuits while providing a protective fuse or circuit breaker for each circuit in a common enclosure.
230/240-volt incandescent light bulb with E27 screw baseEdison screw (ES) is a standard lightbulb socket for electric light bulbs. It was developed by Thomas Edison (1847–1931), patented in 1881, [1] and was licensed in 1909 under General Electric's Mazda trademark.
