What is the short circuit capacity of a BS88 fuse?
daz-daz, BS88 type fuses were always considered as industrial fuses. As far as i remember rated at 415 vac/250 vdc and had a 80KA(ac)/40KA(dc) breaking capacity.. HRC fuses for domestic and smaller commercial installation were to BS1361.
How does a BS88 fuse work?
(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 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 is short circuit capacity?
Circuit breakers and IEC/EN 60898-1 The service short-circuit breaking capacity (Ics) is the breaking capacity according to a specified test sequence that does include the capability of the circuit breaker to carry 85 percent of its nontripping current for a specified time.
What is a Type 2 fuse?
BS1361 type 2 fuses are used as a house service cut-out main fuse and protect an entire house. …
Where is a BS88 fuse used?
A BS88 fuse contains a sacrificial link that breaks during an overload or short circuit scenario to protect the rest of the electrical system. BS88 fuses are used in low voltage industrial and general-purpose applications and meet the requirements of BS88 and IEC60269.
What type of fuse is a BS88?
NIT BS88, IEC269 Industrial HRC Fuse Links Offset Bolted Tags 550V ac 415V ac For Motor Rated Fuse Links In most circuit applications gG fuse links are used. Extended dual ratings of motor circuit protection with gM characteristics are available offering savings in the size and cost of Fusegear equipment.

What is the short circuit capacity of a BS3036?
Cartrdige fuse to BS 1361 type 2 a staggering 33KA rated short ciruit capacity.
What is short circuit capacity of a bus?
Short circuit capacity(SSC). ο The short circuit capacity at a bus is defined as the product of the magnitudes of the prefault bus voltages and post fault current. Short Circuit MVA(3Ο)= π ππππππ’ππ‘* πΌ π π*πππ΄ π ο SSC used to determine the dimensions of the bus bar and interrupting capacity of the circuit breaker.
