Product Details What is this standard about? This part of IEC applies to a. As far as possible, it is in line with the requirements contained in IEC These circuit-breakers are intended for the protection against overcurrents of wiring installations of buildings and similar applications; they are designed for use by uninstructed people and for not being maintained.

Circuit-breakers of this standard are suitable for use in IT systems provided that the requirements of HD are complied with. This standard also applies to circuit-breakers having more than one rated current, provided that the means for changing from one discrete rating to another is not accessible in normal service and that the rating cannot be changed without the use of a tool.

This standard does not apply to — circuit-breakers intended to protect motors; — circuit-breakers, the current setting of which is adjustable by means accessible to the user. For circuit-breakers having a degree of protection higher than IP20 according to IEC , for use in locations where arduous environmental conditions prevail e.

This standard does not apply to circuit-breakers for a. This standard does not apply to circuit-breakers which incorporate residual current tripping devices, which is covered by IEC , IEC , and IEC Supplementary requirements may be necessary for circuit-breakers of the screw-in types.

A guide for co-ordination under short-circuit conditions between a circuit-breaker and another short-circuit protective device SCPDs is given in Annex D. For more severe overvoltage conditions, circuit-breakers complying with other standards e. IEC should be used. For an environment with a higher pollution degree, enclosures giving the appropriate degree of protection should be used.

This standard contains all requirements necessary to ensure compliance with the operational characteristics required for these devices by type tests. It also contains the details relative to test requirements and methods of testing necessary to ensure reproducibility of test results.

They are both standards that specify requirements for low-voltage circuit breakers. Is there more in common? Which one if for homes, which one for industry? IEC , which I introduced at length in the first of these blog posts , governs CBs for industrial applications. They protect electrical power distribution of up to volts a. As for IEC , it relates to the a.
