What is a BS 88 fuse?
Eaton’s Bussmann British standard fuses can be used in multiple applications; industrial, utility, street lighting and domestic. Full range of rated current, voltage available as well as compatible fuse holders. They meet the BS88 part 1 and 2 and IEC 60269-1 and -2 standards. Rated current.
How does a BS 88 fuse work?
The lower the fuse rating, the quicker it will internally disintegrate. (Inside the BS88 fuse body is the fuse wire/wires which are surrounded by sand. The fuse clears the fault once the wire/wires are melted inside the sand). So the fuse is melted by energy which is the I2T number you are referencing.
What are gG fuses?
As a first approximation – “gG” are general purpose fuses (i.e. normal ones) and “aM” are “motor” fuses (i.e. ones intended to withstand the startup surges from motors or other similar equipment) – typically providing a higher rated fusewire element within a lower rated cartridge (e.g. 20M25) and often only used to …
What are gM fuses used for?
“g” stands for full-range breaking capacity, meaning that the fuse is capable of breaking all overcurrents from its minimum melting current up to its breaking capacity. These fuses can protect from overloads and short circuits. Full-range breaking capacity fuses can be used as sole protective devices.
What is a BS 88?
A fuselink is a device comprising a fuse element or several fuse elements connected in parallel enclosed in a cartridge, usually filled with an arc-extinguishing medium and connected to terminations, the fuselink is the part of a fuse which requires replacing after the fuse has operated. ( BS 88)
What type is a BS 1361 fuse?
BS 1361 is the British Standard number for HRC cartridge fuses in household consumer units and similar applications. We have a range of sizes from 5 to 100 Amps. BS1361 type 1 fuses are used in older household consumer units (fuse-box).
What is the difference between gG and gL fuses?
gG and gL is the same thing where gL is an older definintion. The application cateogory is a two-digit code. The first letter is a if the fuse is for short-circuit protection only; an associated device must provide overload protection.
How many watts can a 1 amp fuse handle?
How many watts can a 1 amp fuse handle? 3kWatts divided by 230 = 13.04amps. 3000 Watts is the maximum it is safe to put on a 13amp fuse in a plug.
What is the breaking capacity of a 3036 fuse?
Rated breaking capacity ‘ 4 kA at a lagging power factor of 0.7 to 0.8 for category of duty S4A. BS 3036 fuses are also tested in circuits with a power factor of 0.4 to 0.5 lagging at a current of between 5 and 7 times the minimum fusing current†.
What is a disadvantage of a BS 3036 fuse?
Disadvantages of Cartridge Fuses. They are more expensive to replace than rewirable fuse elements. They can be replaced with an incorrect cartridge. The cartridge may be shorted out by wire or silver foil in extreme cases of bad practice. They are not suitable where extremely high fault currents may develop.
What is a BS 3036 fuse?
BS 3036 semi-enclosed fuses, more commonly known as rewireable fuses, they are still recognised in BS 7671. They may be provided for new installations and may continue to be used in existing installations.
What do you need to know about a bs88 fuse?
BS 88 cartridge fuses for voltages up to and including 1000 V a.c. and 1500 V d.c. Definition of Fuse. A fuse is a device that, by the fusion of one or more of its specially designed and proportioned components, opens the circuit in which it is inserted and breaks the current when this exceeds a given value for a sufficient time.
Is there a GG that is bs88-2?
So BS88-2 has nothing to do with gG. There can be a gG that is BS88-2 Currently we have BS 88 withdrawn on 30 Nov 2010 and replaced by BS HD 60269-2:2010…………which is DUAL NUMBERED as BS 88-2:2010. Let the wind blow you, across a big floor.
When did the British standard for Fuses come out?
The first British specification that defined the performance requirements of fuses for BS 88 was introduced 1919. In the time before exists a wide variety of fuses, but without national, British Standard. The first definition of British Standard 88 was limited to the fuses of that time.
What’s the difference between BS 88 and BS 88-3?
I believe BS 88-3 is the replacement for the withdrawn BS 1361 that cover the fuses originally used for domestic supply cut-outs, etc, but the details are not exactly the same.
