Hyundai Molded Case Circuit Breaker 400A 30KA Model: HGM400E Fixed Type
- 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-circuit.
- 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
