What type is bs3036?

The requirements applicable to rewireable (semi-enclosed) fuses are specified in BS 3036: Semi-enclosed electric fuses. Semi-enclosed fuses are restricted to a.c. circuits. There are three basic types of BS 3036 fuse, categorized according to duty. These categories of duty are S1A, S2A and S4A.

What are the advantages of bs3036 fuses?

Advantages of Cartridge Fuses

  • They have no mechanical moving parts.
  • The declared rating is accurate.
  • The element does not weaken with age.
  • They have small physical size and no external arching which permits their use in plug tops and small fuse carriers.
  • Their operation is more rapid than semi enclosed fuses.

What is a BS 1361 fuse?

BS 1361 is the British Standard number for HRC cartridge fuses in household consumer units and similar applications. 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.

What are BS 3036 fuses?

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.

Why is fuse not used in neutral wire?

Because the fuse can disconnect the circuit only when the excess current flows completely through the neutral. Since, neutral is not a live conductor coming from the source, disconnecting a neutral line can only open the current path through neutral. But, the live phase still carries the charge.

What are BS88 2 fuses 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 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 …
