Circuit-breakers to BS EN 60898-1 may look identical to those complying with BS EN 60947-2 but they are not necessarily inter-changeable. Alternatively, the maximum Zs value can calculated using the time- current characteristic of the MCCB being used, as shown in Fig. Due to the high level of protection performance of these CBs, they should be used at least for the incoming electrical switchboards in buildings applications. 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. Tripping characteristics describe the operational and tripping behavior of miniature circuit breakers in the event of an overload or short circuit. Curve Z is developed for applications with very low inrush currents. if it does, you split into 2 or more circuits. However, fuses remain a highly effective option for overcurrent protection. legrand 32 amp mcb circuit breaker 06163 05172tz bs en 60898 . British Standards Institution, 1. Two standards that specify requirements for low-voltage circuit-breakers (cbs) have been causing confusion for some time among designers and installers of electrical installations. Where cbs made by a different manufacturer are to be installed, verification will have to be undertaken by the manufacturer of the distribution board to BS EN 61439-2 or BS EN 61439-3. IEC 60898-1 relates to a.c. low-voltage circuit breakers for household and similar applications also known as MCBs (miniature circuit breakers) which we find in homes, schools, shops, and office electrical distribution switchboards.

Strange question for you, I know you dont have crystal balls :) but can anyone give me any clue on the following They are intended for use in pollution and humidity-free environments where their operation is by uninstructed persons. Appx 4 in the regs takes you through circuit design, albeit quite in depth. Therefore, manufacturers tables should be consulted for the rating of the MCCB to be used. Hi guys, I have come across two problems today well acutely three so I will list them first.. Applications where short circuits currents may exceed 1,000 amps require more expensive breakers. Without a subpoena, voluntary compliance on the part of your Internet Service Provider, or additional records from a third party, information stored or retrieved for this purpose alone cannot usually be used to identify you.

Please contact our Customer Service team on Email: standards@saiglobal.comPhone: +44 0203 327 3140. I mean Schneider MCBs. The maximum earth fault loop impedance values (Zs) in BS 7671 or the equivalent tables in the IET On-Site-Guide (OSG) and IET Guidance Note 3 Inspection and Testing (GN 3) are essential references when carrying out Zs tests. For example, Schneider, recommend using a factor of 0.8. Like Tel says , size of mcb depends on size of cable, size of cable depends on size of load. Or take the tripping characteristics: IEC 60898-1 clearly describes B, C, and D curves with ratio to rated current, while in IEC 60947-2 the instantaneous tripping release may be adjustable according to the need of the user, or pre-defined by the manufacturer, with 20% tolerance. Hello Vlad, our customer need 10kAIC circuit breaker for Lighting / C.O. As you can see, breaker performs 7,5kA service capacity which is applicable for both standards requirements to declare. More details you can find in my blogs about 60947-2 standard (https://blog.se.com/tag/iec-60947/). ICU and ICN. Dear Amey, Difference is in the breaking technology and size. 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. You need to be logged in to add this standard to your Watchlist. on circuits with high start up currents, e,g. normal. Those basic tech specs alone tell us just how different the use of circuit breakers (CBs) are as defined by the two standards. The metal either melts or it does not. How to verify MCB functioning well on site? Answer (1 of 5): [1] DISADVANTAGES:- Expense While inexpensive options exist, low-cost MCBs offer limited protection against short circuits. SPECIFICATION FOR CIRCUIT-BREAKERS FOR OVERCURRENT PROTECTION FOR HOUSEHOLD AND SIMILAR INSTALLATIONS. Although cbs from different manufacturers may appear similar, the technical performance, dimensions and terminations are not always compatible. From your article I get that IEC 947-2 has stronger specs more than IEC 898-1 such as ( Ue , Ui , pollution degree) but how Icu for 947 ( stronger conditions ) can be greater than 898 for the same MCB, Dear Mostafa, in IEC 898-1 it is mainly used definition of Icn (rated (nominal) breaking capacity) but not Icu (ultimate breaking capacity) and it makes the difference. 1 is for AC, 2 is for DC.
