Mccb Moulded Case Circuit Breaker Mccb Circuit Breaker

HYCM1 250a moulded case circuit breaker/MCCB
**Product Description:
HYCM1 series molded case circuit breaker/MCCB (hereinafter referred to as breaker) is designed by company with international advanced technology, and it is one of the new circuit breakers in the development.
The rated insulation voltage of circuit breaker is 800V, which is suitable in the distribution network with AC 50Hz or 60Hz, rated working voltage of 690V and rated working current from 6A to 1250A. It is used to distribute power and protect the circuit and power equipment against overload, short circuit, under voltage and many other damages. It also can be used as infrequent starting, overload, short circuit, under voltage protection of motor.
The circuit breaker has small volume, high breaking, short arcing (or no arcing) and other characteristics. It is ideal product for the user.
Breaker can be mounted vertically (ie, vertical mounting) or horizontally (horizontal mounting)
This product complies with GB140048.2 and IEC60947-2 standards.
Note: 4 poles mccb is divided into four kinds
N pole of A type doesn’t mount overcurrent tripping component, and N pole always switches on, it can not be on and off together with other 3 poles;
N pole of B type doesn’t mount overcurrent tripping component. It can be on and off together with other 3 poles (On fist, then off);
N pole of C type mount overcurrent tripping component, it can be on and off together with other 3 poles (On fist, then off);
N pole of D type mount overcurrent tripping component, and N pole always switches on, it can not be on and off together with other 3 poles;
