What are BS88 2 fuses used for?

What are BS88 2 fuses used for?

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 2?

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’.

How does a BS88 fuse operate?

(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 is a BS 88 2?

BS 88-2-1:1988 Cartridge fuses for voltages up to and including 1000 V a.c. and 1500 V d.c. Specification for fuses for use by authorised persons (mainly for industrial application). Supplementary requirements (AMD 6684) (AMD 8741) (AMD 10493) (AMD 13814) (Renumbered to BS EN 60269-2:1995)

What is the difference between bs88 and bs1361?

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 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 short circuit capacity of a bs88 fuse?

The standardised values of Breaking Capacity are 80kA for voltages of 415V a.c. and above, and 40kA for d.c. applications.

What is a Type 2 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 does a Type 2 circuit breaker work?

Type I Circuit Breakers – Automatic Reset, which means the circuit breaker keeps cycling on and off until the overload is removed. Type II Circuit Breakers – Modified Reset or Non Cycling, where the circuit breaker doesn’t reset until the overload is removed or the power is turned off.

What is Type 2 short circuit protection?

Type 2 protection provides confidence that motor control components will be operable following a short circuit fault. This reusability translates into hundreds or even thousands of dollars in savings due to reduced downtime and replacement costs.

What is a Type 2 circuit-breaker?

Type II – Modified Reset Non-cycling, remains in open position while there is power to the circuit. Resets when ignition is turned off. Type II circuit breakers are typically used in applica- tions where fuse replacement is objectionable, such as power window, seat and sunroof circuits.

What is the breaking capacity of a bs88-2 fuse?

in the on-site guide i think it states 50ka for BS88-2. As far as I understood it BS 88 Parts 2 or 6 is 80KA breaking capacity. BS 1361 type 2 is most common for domestic @ 33 KA. BS1361 type less common is 16.5 KA. I have come across all three in domestic installations. BS88 fuses can be and are used as main fuses in dom inst.

What are the a and B types of fuses?

A and B types – gM curve Ratings A type A1 : 20A A2 : 30A A3 : 63A A4 : 100A and 200A Approval Asta 20 Certified • The fuse complies with standard EN 60269-2 section II and standard BS 88 part 2.

What is a British standard 88 fuse?

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. It was generally redefined in 1931, giving the time, temperature and other definition how the fuselink has to function.

What does bs88 mean?

The first definition of British Standard 88 was limited to the fuses of that time. It was generally redefined in 1931, giving the time, temperature and other definition how the fuselink has to function. Since this time BS88 has several time be revised.
