The present disclosure relates to an extinguishing unit for a molded case circuit breaker, and more particularly, to an extinguishing unit for a molded case circuit breaker that has grids double-arranged in an extinguishing part to improve arc extinguishing performance. According to an embodiment of the present disclosure, an extinguishing unit for a molded case circuit breaker includes a pair of side plates arranged to face each other and a plurality of grids arranged in a space defined between the pair of side plates, wherein the grids include a plurality of first grids arranged at a front portion of the pair of side plates; and a plurality of second grids arranged at a rear portion of the pair of side plates, wherein a re-division space for re-dividing an arc is defined between the first grids and the second grids.

Extinguishing unit of molded case circuit breaker

Provided is an organic light-emitting device including a first electrode, a second electrode disposed opposite to the first electrode, an emission layer disposed between the first electrode and the second electrode, and an electron-transporting layer disposed between the emission layer and the second electrode. The electron-transporting layer includes a first electron-transporting material and a second electron-transporting material. The lowest unoccupied molecular orbital (LUMO) energy level of the first electron-transporting material (EL) and the lowest unoccupied molecular orbital (LUMO) energy level of the second electron-transporting material (EL) satisfy the equation 0.1 eV&#x2266;|EL&#x2212;EL|&#x2266;0.3 eV.
