Dear Mehdi-Mohammadian, Some electricians argue that fuses offer more of an incentive for homeowners to address the root cause of an overcurrent event, mainly because frequently replacing melted fuses can become expensive and frustrating. The fast trip time of these devices minimizes damage to control circuit conductors from low-level faults. In order to use AC breaker in DC applications you should follow manufacturer recommendations. This means that the tabulated maximum Zs values of Tables 41.2, 41.3 and 41.4 need to be adjusted accordingly. IEC 60947-2 governs circuit breakers (CBs) for industrial applications. The technical storage or access is required to create user profiles to send advertising, or to track the user on a website or across several websites for similar marketing purposes. As you can see, breaker performs 7,5kA service capacity which is applicable for both standards requirements to declare. In other words in the final distribution electrical switchboards of buildings in which the nominal current does not exceed 125A. 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? But because circuit breakers are more complicated pieces of equipment, they have a higher cost of installation and repair. 60898 is an IEC standard; there are two parts. Calculate the maximum measured Zs. They are intended for use in pollution and humidity-free environments where their operation is by uninstructed persons. MCCB standard is IEC60947 and MCB is coming under IEC 947 & 898. BS 3871 Part 1 was withdrawn on the 1st July 1994. However, if you have a choice to install either a breaker box or a fuse box for a new or renovated home, the choice is based completely on how much importance you give to the advantages and disadvantages of circuit breakers and fuses. I was just about to book an EICR inspection for my property when the decorator said he didn't think the fuse board would pass. 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. The technical storage or access is necessary for the legitimate purpose of storing preferences that are not requested by the subscriber or user.

Please contact our Customer Service team on Email: This product cannot be added to your cart right now. In this article, we will show you the tripping characteristics (trip curves) of circuit breakers. Utilities and manufacturing facilities often use air circuit breakers (ACBs), molded case circuit breakers (MCCBs), and miniature circuit breakers (MCBs). This is the reason why manufacturers additionally provide a wide scope of different curves: K, Z, MA. 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. I have been trying to find the BS numbers for various breakers, cut outs and MCB's and fuses. the rating if the device must be less than the current capacity of the cable ( allowing for derating ), e.g. 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. Advantages and Disadvantages of Microgrids. Please enter a valid email address (See below curves). Hunker may earn compensation through affiliate links in this story. I have never confused them yet maybe because its not much since I started working.Anyways the information was very useful and Im sure I will need it in future. 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. From Table B6 of the OSG, the maximum measured Zs value is1.75 at an ambient temperature of 10oC.

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. When too much current runs through a circuit breaker, either the metal strip bends and flips the switch, or the magnet becomes strong enough to pull a metal lever that flips the switch. Best Answer. Icu is the maximum short-circuit current that the circuit- breaker can break without damage which might be 6,000 A or 10,000 A and in the case of MCCBs, 200,000 A for specific voltage ratings. 01-01-1991, Publisher: We use Siemens breakers and they have a SCCR rating of 10KA as per IEC 60898. If such recommendations do not exist its better to use dedicated DC offer. Please contact our Customer Service team. (See below curves), Electromagnetic Trip Curve: This is the trip curve for the coil or solenoid. However, as the resistance of conductors tends to increase with temperature, the ambient temperature at which testing is carried out is a significant factor in determining the temperature (and therefore the resistance) of conductors. Following IEC 898-1 ratio between Icn and Ics (service breaking capacity) shall be: SPECIFICATION FOR CIRCUIT-BREAKERS FOR OVERCURRENT PROTECTION FOR HOUSEHOLD AND SIMILAR INSTALLATIONS. -and by email From Fig 2, the MCCB trips instantaneously at 20 times In (32 A) which equals 640 A. What is the difference between short circuit values mentioned in the 2 standards , Icn values in IEC60898 & Icu value in IEC60947. MXN In contrast, Table 41.3 of BS 7671 gives values suitable for all BS EN 60898 MCBs and BS EN 61009-1 RCCBOs. The two major components of the trip curve are: With lower overload currents, only the thermal trip is active. EN 60898-2/prA1-2002 But Im still confused in case of MCBs that have 2 condition of breaking capacity depend on which IEC that MCB comforting to, Lets take an example of MCB iC60N Assemblies such as distribution boards are validated with specific circuit-breakers installed and these cbs are usually from the same manufacturer as the distribution board.
