Typically IEC 60898-1 certified circuit breakers meet required performance to prove proper protection of household installations: Pollution degree 2, impulse voltage 4kV, isolation voltage is the same as nominal voltage 400V. You should keep it simple: residential installations IEC60898-1, industry and commercial buildings IEC60947-2 & IEC60898-1. The most suitable solution is for MCBs that are certified by both IEC standards since their performance meets requirements for use in residential installations and is high enough for use in industry and infrastructure applications. As you can see, breaker performs 7,5kA service capacity which is applicable for both standards requirements to declare. I have mid eighties Looks like someone wants their homework doing. However, fuses remain a highly effective option for overcurrent protection. Calculate the maximum Zs value. They are intended for use in pollution and humidity-free environments where their operation is by uninstructed persons. Hello Sumith, They should disconnect automatically as soon as the combination of the current rise and duration causes the cable or a component to heat up excessively. Like Tel says , size of mcb depends on size of cable, size of cable depends on size of load. You need to be logged in to add this standard to your Watchlist.

All in all there are so many interrupting ratings that I am so confused. Circuit-breakers to BS-EN 60898-1 are used for household and similar installations and are also commonly found in retail premises, schools and offices. The two major components of the trip curve are: With lower overload currents, only the thermal trip is active. The earth fault loop path from which the earth fault loop impedance (Zs) is derived in shown in Fig. Is it OK to use it. In any case it will break 15kA. Where manufacturers values of Zs for MCBs are used, they will often recommend multiplying the measured value of Zs by a correction factor, to correct for ambient temperature. Hunker may earn compensation through affiliate links in this story. Does it mean that the trip kA is different when the breaker is used for residential or non residential use? But what if the manufacturer of a particular overcurrent device provides a maximum Zs value for the device which differs from the corresponding value in BS 7671? It is usually stated in percentage 100%, 75%, 50% or less. How to Check Whether a Multimeter is Working or Not!

Hello Lim, I want to ask you that. Can BS EN 60898-1 be used instead of BS EN 60947-2? But somewhere on the breaker it says Icu 20 KA . Dear Abdullah, To allow electricity to pass through again normally, reset the switch manually. The rating is the same in DC, there is a new magnetic threshold and voltage limitation. An MCB designed for indoor, pollution degree 2 conditions would be inadequate for harsh, outdoor applications that require pollution degree 3. Required fields are marked *. If the field of installation is commercial buildings or industry, Icu=10kA is proper solution. and 50 kA Icu conforming to IEC 60947-2 380415 V AC 50/60 Hz. For a cable having thermoplastic insulation with a maximum permitted temperature of 70C, this adjustment can be made by simply multiplying the maximum Zs values in the appropriate table by 0.8 (Appendix A2 of GN 3). SPECIFICATION FOR CIRCUIT-BREAKERS FOR OVERCURRENT PROTECTION FOR HOUSEHOLD AND SIMILAR INSTALLATIONS. and that link is unavailable too. I have a customer that requested kwh meters on the socket circuits of an office lock he rents out,(rooms are rented separately). You must replace a fuse once it serves its purpose, but circuit breakers operate via a switch that you simply reset. From Table B8 of the OSG, the correction factor is 1.06.

Advantages and disadvantages of full wave rectifier. I mean Schneider MCBs. But the BS EN 60947-2 standard prescribes an instantaneous tripping release which may be provided with a plus or minus 20% tolerance and adjustable as illustrated in Fig. 40.00 + 17.20 p&p . Knowlhill Milton Keynes MK5 8PG Hi guys, I have come across two problems today well acutely three so I will list them first.. Can anyone help? The requirements of BS 7671 for automatic disconnection are satisfied when: Ia = current causing the automatic operation of the protective device within the time given in Table 41.1. It is a mechanical device that disturbs the flow of high magnitude (fault) current and in additions performs the function of a switch. Circuit-breakers to BS-EN 60947-2 are frequently used for industrial applications in utilities and manufacturing industries. In other words in the final distribution electrical switchboards of buildings in which the nominal current does not exceed 125A. The electromagnetic trip is two to three times the rated current of the supplementary protector (2~3 x In). You already added this Product in the Watchlist. Dear Sumedha, Unfortunately I have no answer for the question. Reference ambient temperature is 30C for households. Therefore, manufacturers tables should be consulted for the rating of the MCCB to be used. You have selected more than three (3) trainings. CAD THIS MUST BE HIGHLITED EVEN MORE BY IEC COMMITTEE TO AVOID ERROR. Dear Max, you should verify the inrush current of the inductive load first. Your email address will not be published. The high instantaneous trip level prevents nuisance tripping, and components being protected can typically withstand higher fault currents without being damaged. Some manufacturers state that their cbs with a short-circuit capacity of say, 10 kA comply with BS EN 60898-1 and the same cb with a short-circuit capacity of 15 kA complies with BS EN 60947-2.
