14x51mm Ac Fuse Holder

China Suppliers ICHYTI Customized 14x51mm ac fuse holder Price is a disposable circuit protection component typically made of low melting point lead-tin alloy, zinc, copper, or silver in the form of a wire or sheet. When the current in the circuit is too high, the metal wire or piece inside the fuse will melt due to high temperature, causing the circuit to interrupt and protecting the circuit from damage. The traditional fuse needs to be manually replaced with a new one after it blows in order to restore the circuit to operation.

ICHYTI 14x51mm ac fuse holder Feature

◉ When used to protect stable loads without starting process (such as lighting circuits, resistors, electric furnaces, etc.), the rated current of the fuse should be slightly greater than or equal to the rated current in the load circuit.
◉ When used to protect a single long-term motor, the current rating of the fuse can be selected based on the maximum starting current, or the following formula can be used: IRN ≥ (1.5～2.5)IN
Among them, IRN is the rated current of the fuse, and IN is the rated current of the motor. If the motor needs to be started frequently, the coefficient in the formula can be appropriately increased to 3-3.5, and the specific value should be determined according to the actual situation.

ICHYTI 14x51mm ac fuse holder Differences from circuit breakers

Both fuses and circuit breakers can achieve short-circuit and overload protection of the circuit, and their similarity is that they can achieve short-circuit protection in case of circuit abnormalities. The principle of a fuse is to use current to flow through a conductor, causing it to heat up. After reaching the melting point of the conductor, the conductor melts and cuts off the circuit to protect electrical appliances and circuits from being burned out. 

Because the melting of the melt requires accumulated heat, fuses can also achieve overload protection. Once the melt burns out, it needs to be replaced. Unlike this, the principle of circuit breaker to achieve circuit breaker protection is achieved through the bottom magnetic effect of current (electromagnetic release), while overload protection is achieved through the thermal effect of current, rather than fuse, so there is no need to replace components.
