SR HD 384.4.43 S2:2004

Electrical installations of buildings -- Part 4: Protection for safety -- Chapter 43: Protection against overcurrent

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.
