1 Scope This standard applies to controllers and starters, which may include a series mechanical switching device, intended to be connected to circuits, the rated voltage of which does not exceed 1000V a.c. This standard characterizes controllers and starters with and without bypass means. Controllers and starters dealt with in this Part are not normally designed to interrupt short-circuit currents. Therefore, suitable short-circuit protection (see 8.2.5) shall form part of the installation, but not necessarily of the controller or starter. In this context, this Part gives requirements for controllers and starters associated with separate short-circuit protective devices. This standard does not apply to: -The motor speeds of the continuous operation a.c. motors at abnormal speed; -Semiconductor equipment controlling non-motor loads, including semiconductor contactors (see 2.2.13 of GB 14048.1); -Electronic a.c. power controllers covered by IEC 60146. Contactors and control circuit devices used in controllers and starters shall comply with the requirements of their relevant product standard. Where mechanical switching devices are used, they shall meet the requirements of their own national standard, and the additional requirements of this Part. The object of this Part is to state as follows: -The characteristics of controllers and starters and associated equipment; -The conditions with which controllers and starters shall comply with reference to: a) Their operation properties; b) Their dielectric properties; c) The degrees of protection provided by their enclosures where applicable; d) Their construction; -The tests intended for confirming that these conditions have been met, and the methods to be adopted for these tests; -The information to be given with the equipment, or in the manufacturer's literature.
