HSM2E Series Electronic Moulded Case Circuit Breaker

1.Application
HSM2E series Intelligent Molded Case Circuit Breakers (MCCB in brief hereinafter) are suitably applied in AC *0Hz electric grids with rated Insulation voltage **0V,rated working voltage **0V,rated current *2A ~ **0A for electric power distribution and for infrequent switchover under normal conditions as well as for protection of circuits and equipment against overload, short circuit and under-voltage.
Apart from three stage protection, the backup protection with short circuit instantaneous feature in magnetic trip, make the product more reliable.
The MCCB has disconnecting function and its corresponding symbol is shown as . 

The installation mode of the MCCB may be both vertical and horizontal.
The MCCB can not reverse wiring, NO.1,NO.3 and NO.5 for power supply, NO.2,NO.4 and NO.6 for the load.
The MCCB has isolated function with a corresponding symbol of
The MCCB complies with standards:
IEC ******1
IEC ******2
