Structure and Movement(ODP)

1. Arc-extinguish Device
It is designed as a structure that can disperse, cool the arc between contacts to be extinguished efficiently when breaking a large current instantly generated by arc grid arranged in parallel.

2. Full Electronic (ODP) Structure
It is designed as a structure that can disperse, cool the arc between contacts to be extinguished efficiently

3. Checking the movement by handle Trip display Incase of auto-breaking due to accidental current such as overcurrent, short-circuit current, handle is stopped at the position in the middle of between ON and OFF. Reset operation In case of Trip due to accidental current, remove the cause of accident and reset the handle to OFF by hand and then to ON for normal operation.

4. Improved quality with the durability of product by using special materials

Structure and Movement (Thermal Magnetic)

1. Arc-extinguishing Device It is designed as a structure that can disperse, cool the arc between contacts to be extinguished efficiently when breaking a large current instantly generrated by arc grid arranged in parallel.

2. Current Limiting Structure
Newly developed current limiting structure sharply decreases and cuts off arc energy without fail.

3. Simultaneous Trip Structure
There is no fear of single-phase running of three-phase motor because three-phase is cut off simultaneously even though electric current flows on any one phase.
