Where is low-voltage switchgear testing done? The BAIJIAN testing platform will develop a low-voltage switchgear testing plan based on customer needs, conduct testing and analysis on designated items of samples according to relevant standards, and issue authoritative and effective low-voltage switchgear testing reports
Testing standards:
GB/T 14048.4-2020 low-voltage switchgear and control equipment - Part 4-1: Contactors and motor starters - Electromechanical contactors and motor starters (including motor protectors)
Scope of application:
This part specifies the characteristics of
electrical appliances.
Applicable conditions for the following aspects:Operation and performance, dielectric performance, protection level, structure, including safety measures to prevent electric shock fires and mechanical hazards.
The test used to confirm that the electrical appliance meets these conditions, as well as the test method The information to be provided on the product or in the manufacturer's documentation This section also specifies the evaluation procedures for electromechanical overload protection in safe places, such as protecting motors located in explosive environments from external environmental influences (see Appendix L)This section applies to:
- electromechanical contactors and starters, including motor protection switchgear (MPSD)
- Operator of contactor type relay
- Special contacts for contactor or contactor relay coil circuits
- Special accessories (such as special wiring, special lock buckle accessories) The above electrical appliances are connected to the distribution circuit, motor circuit, and other load circuits, with a rated voltage of AC not exceeding 1000 V1 or DC not exceeding 1500 V
