| Title | Electrical installations of buildings - Part 4: Protection for safety - Chapter 43: Protection against overcurrent |
| Project Number | 11806 |
| Abstract/Scope | Sets out general rules for protection of live conductors against overload and short circuit. Specifies the features of various protective devices and necessary coordination between conductors and overload protective devices. Formula for calculation of time in which a given short-circuit current will raise a conductor from the highest admissible temperature in normal duty to its limit temperature. Enumerates requirements for coordination of overload and short-circuit protection. Note: For details of -low-voltage circuit breakers, see EN 60974-2 -low-voltage fuses, see EN 60269 -for coordination of low-voltage direct-online (full voltage) motor starters with short-circuit protective devices, see EN 60974-1 -for current-carrying capacities of conductors for electrical installations of buildings, see IEC 60364-5-523. |

| Normative reference (6) |
(1) Date of ratification (dor) date when the Technical Board notes the approval of an EN (and HD for CENELEC), from which time the standard may be said to be approved
(2) Date of availability (dav) date when the definitive text in the official language versions of an approved CEN/CENELEC publication is distributed by the Central Secretariat
(3) Date of announcement (doa) latest date by which the existence of an EN (and HD for CENELEC), a TS or a CWA has to be announced at national level
(4) Date of publication (dop) latest date by which an EN has to be implemented at national level by publication of an identical national standard or by endorsement
(5) Date of withdrawal (dow) latest date by which national standards conflicting with an EN (and HD for CENELEC) have to be withdrawn
(6) This list of normative references is purely indicative. The only official list of normative reference is the list of the published standard.
