4 Pole MCCB Low Voltage Power Moulded Case Circuit Breaker For Motor Protection
Description:
ABS/ABE seriesmotor protection circuit breaker is suitable for industrial or commercial power and lighting with AC50/ 60Hz, rated working voltage up to AC600V/DC250V, rated current up to 630A.
Its a kind of economical breaker with the characters of stable and reliable function, beautiful appearance, small size and long life. It can be used for conversion of line and infrequent starting motor.
It can also be attached to install the accessories which have protection function for avoiding loss-voltage, under voltage.
The product can install connection line with front board and back board, it also can equip hand-operating apparatus or motor-operating apparatus to control in a remote distance.

Environmentally-friendly
A. The ABS/ABE series MCCB does not contain any noxious or hazardous substances, and its manufacturing and processing processes are performed in accordance with the requirements of the ISO 14001.
B. Environmentally-protective materials are used in the course of distribution.
C. Low temperature rise, low power consumption, and minor influences to the surrounding environment during operation.
D. Over 80% o f its component materials can be recycled and reused at the end of its service life.
Modularized Design:
Circuit breakers: For the same frame size MCCB, the dimension is the same whatever the breaking capacity, rate current is
Accessories: The users may select accessories randomly as per their demands and expand the functions of the circuit breakers.
