KB0-16C control protection switch description:
CPSN ( KB0N ) reversible type control and protection switch
In CPS ( KB0 ) as the main switch, and a mechanical interlock and electrical interlocking attachment assembly, constitute a reversible control and protective switching devices ( KB0N CPSN ), applicable to the motor of reversible or two-way control and protection.
Main circuit parameters and the attachment module with basic type
CPSD ( KBOD ) double speed type control and protection switch
In CPS ( KB0 ) as the main switch, and the contactor, electrical interlocking attachment assembly, consisting of two speed motor controller CPSD ( KB0D ), suitable for double speed motor control and protection.
Double speed motor controller is configured with three:
The configuration of a: high-speed fire type ( overload, overcurrent alarm only not trip ), low speed as the basic type;
The configuration of two: high, low speed are the basic type;
The configuration of three: high, low speed are fire type ( should be marked with special orders ).
CPSD3 ( KBOD3 ) three speed type control and protection switch
In CPS ( KB0 ) as the main switch, and the contactor, electrical interlocking attachment assembly, consisting of three speed motor controller CPSD3 ( KB0D3 ), was applied to three speed motor control and protection.

One, overview
CPS" control and protection switch in low voltage electric apparatus" is a new product, as new categories of products, its product category for" CPS"," Control and Protective Switching is the English abbreviation of Device".
CPS ( IKB0 ) meet standards: IEC60947 - 6 - 2: ( 2002)" low voltage switchgear and controlgear - Part sixth multi function electrical section second control and protective switching devices" and GB14048.9 - 1998" low voltage switchgear and controlgear multiple function equipment: control and protective switching devices ( equivalent to" by IEC60947 - 6 - 2 ).
Two, structural purposes:
CPS ( KB0 ) products using modular single product structure, integration of the traditional circuit breaker ( fuse ), contactor, overload ( or over-current, open phase protective relay, starter ), isolators, main function, has the automatic remote control and in situ direct human control function, has a panel indication and electrical signal alarm function with over-voltage, under-voltage protection function, the phase is broken phase protection function, has coordinated time current characteristics ( protection with inverse time limit, and the instantaneous protection characteristic of three section ). According to the need of matching function modules or attachments, can realize the various types of motor load, the load distribution control and protection.
CPS ( KBO ) is mainly used in AC 50Hz ( 60Hz ), rated voltage, rated current to 690V from 3A to 100A, adjustable working current is from 0.12A to 100A power system is switched on, bear and break the normal conditions ( including the specified overload conditions ) under the current, and can be switched on and off, carrying provisions abnormal conditions ( such as the current short circuit ).
From its structure and function, CPS ( KB0 ) series of products is no longer a contactor, or circuit breaker, or thermal relays and a single product, but a set of control and protection system. It appears from the fundamental solution to the traditional using discrete components (usually the breaker or fuse + + overload relay contactor ) due to selection caused by unreasonable control and protection of unreasonable matching problems, especially overcome due to the adoption of different evaluation standards of electrical products are combined together, protection characteristics and control characteristics with the discordant phenomenon, greatly improve the control and protection system reliability and continuous running performance.
CPS ( KBO ) series of products is the breaker ( such as CM1, ABB, NS, C45 ), contactor, thermal relay, such as low-voltage electrical fuses the best alternative products, KB0 series is the upgrading of products.
In three, the product function:
The large instantaneous short-circuit protection: protection current and rated current of the switch main body, its current setting for the 20In + 20%, T4 = 2 ~ 3MS action time.
The instantaneous short-circuit protection: current protection and electronic breaker rated current, the current setting for 16In - 15%, T3 < 0.1ms action time.
The short circuit short-time delay or fixed protection: current protection and electronic breaker rated current, the current setting panel adjustable ( 6 ~ 12Ir1 ) + 15% ( for motor protection), ( 3 ~ 6Ir1 ) + 10% ( power distribution protection ), delay action setting time T2 = 0.2S
The long-time delay overload protection: current protection and electronic breaker rated current, the current setting of Ir1 panel adjustable 0.4 ~ 1Ie, inverse time characteristic for I2T = ( 1.5Ir1 ) 2t1, T1 for long time delay current 1.5Ir1 setting time, distribution by T1 = 64S, T1 = 128s motor
The lack of phase, phase failure protection: action setting time for 2S
The three-phase unbalance protection: arbitrary phase current difference of more than 50%, action setting time for 2S
The overvoltage protection: phase 470 + 10V, 5S action setting time
The undervoltage protection: phase 270 + 10V, 5S action setting time
The start-up delay: short circuit short-time delay or time limit does not protect, setting time for 2S
The fire interface: DC 24V fire interface output ( optional)
The residual current leakage protection: customized according to customer requirements, the action time of 0.1s ( time delay for 0.3s ) ( optional)
The warning function: current adjustable
The online programming function
The fault indicator
The test function
