适用范围：This standard applies to low-voltage switchgear and controlgear assemblies [Type-Tested Assemblies (TTA) and Partially Type-Tested Assemblies (PTTA)], the rated voltage of which does not exceed 1000 V a.c. at frequencies not exceeding 1000 Hz, or 1500Vd.c.NOTE: For higher frequencies, special considerations may be necessary.This standard also applies to assemblies incorporating control and/or power equipment, the frequencies of which are higher. In this case, appropriate additional requirements shall apply.This standard applies to stationary or movable assemblies with or without enclosures.NOTE: Additional requirements for certain specific types of assemblies are given in supplementary standards.This standard applies to assemblies intended for use in connection with generation, transmission, distribution and conversion of electrical energy and for the control of electrical energy consuming equipment. It also applies to such assemblies designed for use under special service conditions, e.g. in ships, in rail vehicles, for machine tools, for hoisting equipment, or in explosive atmospheres, and for domestic (operated by unskilled persons) applications, provided that the relevant specific requirements are complied with.This standard does not apply to individual devices and self-contained components, such as motor starters, fuse switches, electronic equipment, etc, complying with their relevant standards.
