1. Functions and features.
This product adopts modular single structure form, integrated circuit breaker (fuse), contactor,
overload (over current) protector, over and under voltage, lack of phase protector, voltmeter,
ammeter,residual current protection, isolator and other electrical components of the comprehensive
function.MCU digital processing technology, high measurement accuracy, good linearity, accurate
and reliable fault resolution, strong anti-interference ability.
Its features are as follows:
1.1function of remote automatic control and local direct manual control.
1.2panel indication and electromechanical signal alarm function
1.3The product has coordinated time protection characteristics (with long delay, short circuit short
delay, short circuit instantaneous three protection characteristics).
1.4The product has many functions such as phase break, overcurrent, blocking, blocking, short
circuit, undercurrent, overvoltage, undervoltage, residual current protection, three-phase
unbalance, missing phase, isolation, startup timeout, fire fighting, fault signal output and remote
shunt excitation, etc.
1.5monitor for various running, failure and other states using LED (LCD) display. With voltmeter,
current meter function
1.6Products can be set and query various parameters; Because CPS2 adopts MCU E2PROM
memory technology, it can be stored without power after parameter setting and has fault memory
function, which is convenient for fault query and analysis.
1.7It has RS485 communication interface and open field Bus (Mod Bus protocol, etc.), which makes it
convenient for users to integrate the system and realize intelligent management
1.8Load usage category
(1)Motor protection type is suitable for AC—42、AC—43、AC—44、DC—41、DC—43、DC—45、DC-46。
(2)Power distribution protection type applicable forAC-40、AC-41、AC-45a、AC-45b。
