What is BS 1362 fuse?
BS 1362 is the British Standard number for cartridge fuse links used in UK plug tops. BS1362 fuses protect the cables connected to domestic equipment against overloads or small overcurrents. They may also be used in appropriate single-phase installations (for example, fused spur connection units).
What is the breaking capacity of a 1361 fuse?
Semi-enclosed fuses are capable of breaking currents of 1 kA to 4 kA depending on their type. whilst cartridge fuses to BS 1361 will safely break at 16.5 kA for type 1 or 33 kA for type II.
What does 13 amp fuse mean?
Plugs for appliances rated between about 700 watts and 3000 watts (the maximum rating of a wall socket) should be fitted with a 13-amp fuse (coloured brown). For example: 13A Fuse – Washing machine, dishwasher, microwave, kettle, toaster, iron.
What is fuse breaking capacity?
> Breaking capacity is the maximum short circuit current a fuse can safely blow without a catastrophic failure such as a fire, breakage or explosion. > Low and high breaking capacity ratings typically range from 35A up to 10kA.
What is the breaking capacity of a fuse?
Are Rewireable fuses illegal?
The consumer unit (colloquially known as the fusebox) must meet the legal requirements from the time it was installed, even if that was some years ago. Therefore if you do have such a fuse box present, then there’s not necessarily a specific legal requirement to replace it with a modern electrical consumer unit.
What is the breaking capacity of a BS88 fuse?
80kA
The standardised values of Breaking Capacity are 80kA for voltages of 415V a.c. and above, and 40kA for d.c. applications.
What is the difference between BS88 and BS 1361?
BS 88 HRC fuses mainly for commercial and industrial use, can handle up to 80 KA. 1000 V ac, and 1500 V dc. BS 1361 fuses mainly for domestic use,and will have a much lower breaking capacity.
What is a BS 88 2 fuse used for?
The fuse complies with standard EN 60269-2 section II and standard BS 88 part 2. This fuse range insures an excellent current limi- tation for all overloads on a large range of appli- cations. Their size cannot allow exchange by other fuses of higher rating in their range.
What type is a BS 88 2 fuse?
I think most will know that a BS 88-2 fuse is a HBC, a high rating/breaking capacity for, sort of, industrial type applications. You say that ‘industrial’.
What is minimum breaking capacity in fuse?
Breaking capacities In North American practice, approved general-purpose low-voltage fuses must interrupt at least 10,000 amperes. Types used in commercial and industrial low-voltage distribution systems are rated to safely interrupt 200,000 amperes.
How do you choose breaking capacity?
Choosing breaking capacity Supply impedance is calculated from the impedance of the elements making up the supply system. Customers of an electrical supply utility can request the maximum value of prospective short-circuit current available at their point of supply.
