GB/T 14048.9-2008 Low-voltage switchgear and controlgear—Part 6-2:Multiple function equipment—Control and protective switching devices(or equipment)(CPS)

Scope

This part applies to control and protection switchgear (equipment) (CPS) with a rated voltage of no more than 1,000 V AC or 1,500 V DC, which are connected to the main contact circuit.
CPS are used to provide protection and control functions for circuits and can be operated manually or by other means (such as automatic control, remote control, etc.). They can also perform additional functions, such as isolation functions.
Digital inputs and/or digital outputs compatible with PLC in CPS shall meet the requirements of GB/T 15969.2—1995.
The purpose of this part is to specify:
——The characteristics of CPS;
——The conditions that CPS should meet in terms of operating performance, dielectric performance, and enclosure protection level (when equipped with an enclosure);
——The tests used to verify that these conditions are met and the test methods employed;
——Markings on the product or information provided by the manufacturer.
