Hyundai HGE400S ELCB 100-500mA

It is available to adapt various low voltage system protections such as ‘Discrimination’ and ‘Cascading’ with limited current characteristic and high breaking capacity.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 while the other feeder can be used continuously.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 the downstream circuit.
