– Rated Insulation Voltage (Ui) =1000
– Ics = 100% Icu
– Compliance to IEC60947-2
– Type Test approval by DEKRA & JKR
Maximized Insulation Performance
– The safety of the product has been maximized through enhanced insulation voltage
– Rated Insulation Voltage, Ui : 1,000 V
– Rated Impulse Withstand Voltage, Uimp : 8 kV
High Breaking Capacity
Maximum breaking capacity was realized with high breaking capacity in Korea.
Cable Insulation Performance Suitability
In case there is a presence of abnormal condition such as welding of the main contact after tripping of the circuit breaker by realizing the cable insulation performance in accordance with IEC 60947-2, the handle does not move from ON to OFF position. This makes it safe by preventing the operation of circuit breaker caused by the operator’s negligence.
Sealing Structure (Option) Applied
Dial sealing structure is applied to prevent arbitrary change of the current set value using a protection cover (Prevent operation of thermal magnetic adjustment knob) (Option)
Various Low Voltage System Protections
HGM Type MCCB realizes current limiting characteristics and outstanding breaking performance and enables various low voltage system protections such as discrimination and cascading.
Cascading
In case an accident occurs during load, the upstream main circuit breaker operates earlier than the downstream circuit breaker of the accident circuit for back-up protection. It is an economic protection method. Thus, a circuit breaker with lower breaking capacity than the estimated short-circuit current can be applied.
