EZC

CEZC series of MCCB perfect function,ensure 100% reliability and continuity of power supply.

Usage
CEZC series of MCCB are used in distribution network of AC 50/60Hz,rated operationsal voltage 440V and rated current from 15A to 63A,It is used for
distributing power and protecting circuit,power and electrical equipment from
overload and short circuit damage,which improve the reliability and continuity
of power supply.

Perfect function
The breaking capacity covers the common breaking in Level Ⅱpower distribution
   areas and electromechanical market:25KV,36KV and 50KV.Including 1P,2P,3P and 4P products.
Comprehensive range of profection,including low-voltage distribution systems
   protection,motor protection and earth leakage protection.

  Voltage release coil  
  Voltage release coil can trip the circuit breaker by contronlling the signal.
  Unde Voltage Release(UVR/UVRN)
This release trips the circuit breaker when the control voltage drops be low a triping
threshold.
Tripping threshold between 0.35 and 0.7 times the rated voltage.
Circuit breaker closing is possible only if the voltage exceeds 0.85 times the rated
voltage,compliance with IEC60947-2. 
   
Shunt Trip(SHT)  
  This release trip the circuit breaker when the control voltage rises above 0.7 x Un.
  Control signals can be of the impulse type(≧20ms)or maintained.
     
Function  
AX(ON/OF):Indicates the position of the circuit breaker contacts
AL(trip indication):Indicates that the circuit breakers has tripped due to an 
overload,a short-circuit,or operation of a voltage release.
