What is 1a fuse used for?

1 AMP Ceramic Fuse are suitable for various different uses. These include providing reliable performance and cost-effective circuit protection. They are ideal for use in plugs to protect cables from melting or catching fire if they are overloaded.

What does fuse amp rating mean?

An amp or an ampere rating is the current rating for a specific fuse. The current rating of a fuse identifies the allowable current that the fuse can carry without opening under specified test conditions. Each fuse is marked with its current rating.

What is a Type 1 fuse?

BS1361 type 1 fuses are used in older household consumer units (fuse-box). BS1361 type 2 fuses are used as a house service cut-out main fuse and protect an entire house.

How do you choose a fuse rating?

In order to select the right amperage of the fuse, you first need to know the full-load steady-state current of the circuit at an ambient temperature of 25º C (68º F). Once the current value is determined, then a fuse rating should be selected as to be 135% of this value (taken to the next standard value).

How do I choose a fuse rating?

What are the fuse ratings?

The fuse rating relates to the strength of current allowed through the circuit, which changes depending on the type of appliance….What is a Fuse Rating?

  • The wire fuse element heats up quickly.
  • The fuse then melts or explodes, depending on the current.
  • The broken fuse interrupts the flow of electricity.

What happen if fuse rating is too high?

What happens if the fuse has a rating higher than the permitted rating of the wiring? Then the fuse will not blow out even the current rises above the permitted value. Such a fuse remains the circuit close and allows the current to flow beyond the limit permitted to the wiring or other components.

What is the voltage rating of a fuse?

A fuse may be used in circuits where the fuse’s voltage rating is equal to or greater than the circuit voltage, unless otherwise stated on the fuse. For example, the FLSR_ID indicating fuse has a voltage rating of 75–600 volts.

What is the fuse rating for a single lamp?

Hence the fuse standard rating for the individual lamp should be 4A. For the capacitor circuit, the fuse rating is equal to 1.5 times of the full load reactive current by considering staring inrush current, circuit harmonics and capacitor tolerances. The formula will be

What is the fuse rating of a single-phase motor?

For single-phase: Motor fuse rating = P kW x 1.25 / (pf x V (V)) In other words, the fuse rating is equal to 1.25 times the full load current.

What is the standard size of a fuse?

Fuse standard Sizing: We cannot size exact resultant rating of the fuse from the above formula. Instead, we can choose nearest available standard fuse size. They are 1, 2, 3, 4, 6, 10, 16, 32, 40, 63, 125, 150, 160, 200, 250, 315, 355, 450, 500, 560, 630, 710, 800, 1000, 1250, 1600, 2000, 2500, 3200, 4000, 5000, and 6000 amperes.
