1. CPSKB0 Overview
CPS is "Control and protective switching devices" is the new low-voltage electrical products, as a new category of products, its product category, code-named "CPS" (Control and Protective Switching Devices). CPS meet standards: GB14048.9 "low-voltage switchgear and control equipment, multi-function devices (or equipment) Part 2: Control and protective switching devices (or equipment)", IEC60947-6-2 "low-voltage switchgear and control equipment Part 6 Section 2 multi-function electrical control and protective switching devices. "
2. Function
CPSKB0 control and protection switching of a single modular product structure type, integration of the traditional circuit breaker (fuse), contactors, overload (or over-current, phase) relays, starters, main functions such as isolation, automatic control with remote and local direct human control, with the panel, and electrical and mechanical signal indicates alarm function, with coordination of the time - current protection features (anti-time, fixed time and instantaneous protection features three sections), as shown in Figure 4. Optional function modules as needed or accessories, you can achieve the general (non-frequent start) of the motor load, frequent starting the motor load, the load distribution control and protection circuit.
3. Product Type
To CPSKB0 basic control and protective switching products as the main switch, with the combination of various agencies and functions of attachment to form each of the following products:
A. Fire control and protective switching type CPSKB0-F
B. Isolated Control and Protective Switching CPSKB0-G
C. Two-speed motor controller CPSKB0D
D. Three-speed motor controller CPSKB0D3
E. Double power automatic transfer switching equipment CPSKB0S
F. Vacuum starter CPSKB0J, CPSKB0J2, CPSKB0R, CPSKB0Z
G. Reversible Control and Protective Switching CPSKB0N
H. Protect the control box XBK1
I. After the plug-board wiring CPSKB0-R
J. Control and protection of explosion-proof switch box BQD55-CPSKB0
4. Use:
CPSKB0 control and protective switching mainly used for AC 50Hz (60Hz), rated voltage up to 690V, rated current from 0.16A to 125A of the power system, able to turn, carrying and breaking under normal operating conditions, including conditions of current overload, and can turn, load and non-breaking provisions of the current under normal conditions, such as short circuit current. As well as: metallurgy, coal, steel, petrochemicals, ports, ships, railways and other areas of power distribution and motor protection and control systems.
