Description

HGM 400H 3P 300A
Type Molded Case Circuit Breakers
Fixed Thermal and Magnetic Protection

-Cable Insulation Performance Suitability-
In case of continuing abnormal conditions such as welding of main contact
after trip, handle is not available to move ‘OFF position’ in accordance with
IEC 60947-2 cable insulation performance. Also, it is possible to maintain
easily by checking a contact condition by the handle.

-Adjustable Rated Current-
As applying to adjustable rated current design, it is possible to protect circuit
optimally according to the load factor. Adjustable range of rated currents.
(Molded case circuit breakers).

-Discrimination-
It is a low voltage system protection to selectively separate fault point from
system to minimize influence of fault. In this protection type, only circuit
breaker installed at a fault point is operated whilethe other feeder can be
used continuously.

-Cascading-
In this protection type, upstream circuit breakers can be tripped earlier than
downstream circuit breaker for back up protection. So, it is applied to the
smaller breaking capacity than the calculated value at down stream circuit.
