Description

MKLB series Moulded case circuit breaker (herein after called circuit breaker)is one of our new type
circuit breakers, which adopts international advanced design and manufactural technology,
it can be divided into L-type (standard type), M-type(higher breaking type), H-type
(current limiting type)according to the rated ultimate short circuit breaking capacity(Icu).


The MKLB series moulded case circuit breakers(hereinafter referred to as circuit breakers)are suitable for AC 50Hz (or 60Hz)circuits with rated insulation voltage of 1000V(800V for MKLB1-63 and 1140V for MKLB1-1600),rated operating voltage of 400V/690V(1140V for

MKLB11600)and below,and rated operating current up to 1600A for infrequent switching and infrequent motor startig.The circuit breaker has overload,short circuit,and under voltage protection functions,which can protect the circuit and power equipment from damage.

◎ Circuit breakers are classified into L-type (standard type)and M-type (high breaking type)according to their rated ultimate short-cicuit breaking capacity.

◎ This circuit breaker has the characteristics of small volume,high breaking capacity,short arcing,and high vibration resistance.

◎ The circuit breaker has isolation function,and its corresponding symbol is x—

◎ Compliant standards:GB/T 14048.2 IEC60947-2.

◎ This circuit breaker allows for reverse wiring
