IEC 60715 Ed. 1.0 b:1981, Dimensions of low-voltage switchgear and controlgear. Standardized mounting on rails for mechanical support of electrical devices in switchgear and controlgear installations

Specifies dimensional and functional requirements for the compatible mounting of varied electrical devices on some types of rails in switchgear and controlgear assemblies. An appendix gives the standardized dimensions of steel mounting rails with Top Hat, C and G sections. A second appendix provides an application guide for the use of rails.
