The basic requirements of GB 14048.1-2006 include clauses in the General Principles, which will be specifically stated when adopted in this section. The clauses, tables, figures, and appendices cited in this section are all labeled with "GB 14048.1-2006", such as 1.2.3 in GB 14048.1-2006, Table 4 in GB 14048.1-2006, or Appendix A in GB 14048.1-2006. Scope and purpose of application: This section applies to control circuit appliances and switch components used for control, signaling, interlocking, and other purposes in switchgear and control equipment. This section is applicable to control circuit appliances with a rated voltage not exceeding 1000 V AC (frequency not exceeding 1000 Hz) or 600 V DC. For operating voltages less than 100 V AC or DC, see Note 2 of 4.3.1.1. This section applies to the following types of control circuit appliances: ------ manually operated control switches, such as buttons, rotary switches, foot switches, etc.; ------ Electromagnetic operated control switch with delayed or instantaneous action, such as contactor type relay; - indicating switch, such as pressure switch, temperature sensitive switch (thermal switch), programmable controller, etc—— Position switches, such as control switches operated by machines or mechanical components; related control circuit appliances, such as indicator lights. Note 1: Control circuit appliances include control switches and related appliances, such as indicator lights. Note 2: Control switches include switching components and operating systems. Note 3: Switching elements can be contact elements or semiconductor components. This section also applies to specified types of switching components associated with other electrical appliances (whose main circuit meets other standards), such as auxiliary contacts for switching appliances (such as contactors, circuit breakers, etc.), which are not only used for the coils of the appliances; interlocking contacts on the enclosure door; control circuit contacts for rotary switches; control circuit contacts for overload relays
Function of testing report:
