This standard applies to indoor AC contactors and/or contactor-based motor starters used in power systems with rated voltages of 3.6 kV and above but not exceeding 12 kV and frequencies of 50 Hz and below. This standard is only applicable to three-pole contactors and starters in three-phase systems, and single-pole contactors and starters used in single-phase systems. Two-pole contactors and starters used in single-phase systems should be negotiated between the manufacturer and the user. The contactors and/or starters involved in this standard are generally not used to break short-circuit currents, so appropriate short-circuit protection (see 3.4.110.12 and Note 2 below) can be part of the device, but not necessarily part of the contactor or starter. This standard sets requirements for the following devices: - Contactors associated with overload and/or short-circuit protection devices (SCPD); - Starters associated with separate short-circuit protection devices and/or separate short-circuit and overload protection devices integrated therewith; - Contactors or starters combined with their own short-circuit protection devices according to specified conditions. These combined appliances, such as integrated starters (see 3.4.110.9), are considered as a whole. This standard covers contactors used to close and open circuits and, if combined with suitable relays (see 3.6.108), to protect the circuits from possible overloads. This standard also applies to contactor operating devices and their auxiliary equipment. This standard covers motor starters used to start and accelerate motors to normal speed, ensure continuous operation of the motor, cut off the power supply to the motor and provide protection for overloads of the motor and the circuits connected to it. Types of motor starters include: - direct starters - reversing starters - bidirectional starters - reduced voltage starters - autotransformer step-down starters - varistor starters - reactor starters. Starters whose operation depends on thermal relays for protecting motors in accordance with GB/T 14598.15 or thermal protection devices for motors in accordance with GB 13232 do not need to meet the relevant requirements of this standard. Overload relays for starters, including those based on solid-state technology, are included in the scope of this standard. This standard does not apply to: - circuit breaker-based motor starters; - single-pole operation of multi-pole contactors or starters; - two-stage auto-decompression starters for continuous operation in the starting position; - asymmetric variable resistance rotor starters, that is, starters with different resistance values ​​for all phases; - equipment that can start and adjust the speed; - liquid starters and "liquid-steam" starters; - semiconductor contactors and starters using semiconductor contactors in the main circuit; - variable resistance stator starters; - contactors or starters for special purposes. This standard does not involve the components installed in contactors and contactor-based starters, as they have their own technical requirements. The purpose of this standard is to specify: a) the characteristics of contactors, starters and related equipment; b) the relevant conditions that contactors and starters should comply with; - operation and characteristics; - insulation performance; - when applicable, the degree of protection of the enclosure; - structure; - for integrated starters, the interaction between the various components, such as coordination with SCPD. c) tests used to confirm that these conditions have been met, and the methods used for these tests; d) information that should be indicated in the accompanying documents or manufacturer's documents.

This standard applies to AC terminals and/or motor starters based on rectifiers installed in production with rated voltage of 1000 kV or above but not exceeding 12 V and power of 5 H or below. This standard is applicable to three-pole contactors and starters in three-phase systems and single-pole contactors and starters in single-phase power systems. The use of two-pole contactors and starters in single-phase systems should be negotiated between the manufacturer and the user. The contactors and/or starters covered by this standard shall be Starter: Generally, a short-circuit protection device is not required. Therefore, when short-circuit protection is provided (3, 4.11, 3.12 and Note 2 below), it can be part of the device and must not become part of the complete device or the active device. This standard lists the following devices that exceed these requirements:
