Description

CE certificated Electronic Type Moulded Case Circuit Breaker Low Voltage MCCB 63A, 100A,200A, 350A, 500A,800A


◎ The MKB3E series electronic moulded case circuit breakers (hereinafter referred to as circuit breakers)are
suitable for AC 50Hz(or 60Hz) circuits with rated insulation voltage of1000V,rated operating voltage of 400V
and below,and rated operating current of 1250A for infrequent switching and infrequent starting of motors.
The circuit breaker has overload long delay inverse time,short circuit short delay inverse time, short circuit
short delay definite time,short circui instantaneous and under voltage protection functions,as wellas residual
current protection (optional)and phase loss protection function(optional),which can protect the circuit and
powerequipment from damage.The circuit breaker has complete and accurate protection characteristics,
which can improve power supply reliability and avoid unnecessary power outages.The "Z,B"type controller
has a communication interface and can be used for “three remote”to meet the requirements of the control
center and automation system.
◎ Circuit breakers are clasified into two types based on their rated ultimate short-circuit breaking capacity:
L-type(standard type)and M-type (medium breaking type).This circuit breaker has the characteristics of small
volume,high breaking capacity,short arc and high vibration resistance.
◎ The circuit breaker can be installed vertically(i.e.upright)orhorizontally(i.e.transversely).
◎ The circuit breaker has isolation function,and its corresponding symbol is_/
◎ The circuit breaker allowsfor reverse wiring.
