Description

Applications: L7 series MCB has protective function of overload, and is used in lighting distribution system in industry, commerce, dwelling and protect fractional electric motors. They also have many merits of high protective grade (up to IP*0), high breaking capacity, reliable sensitive action, convenient multi-pole assembling and long life. They are mainly adapted to the circuit of AC *0Hz, **0V in single-pole, **0V in double/three/four-pole for protecting overload and short circuit. Meanwhile, they are also used in turning on or off the electric apparatus and lighting circuit under the normal conditions. Features: 1) Conforms to standards of electrical EN****8 (IEC**8), GB*******9 2) Rated current: **0V/**0V, *0/*0Hz 3) Rated breaking capacity: *0kA IEC**8 (0.5 - *3A), *5kA IEC****2 (0.5 - *3A) 4) Short circuit breaking capacity of DC: max. *8V (KL7, *0kA) single-pole, max. **0V (KL*-DC, 6kA) single-pole 5) Performance: C, D characteristic curve 6) Max. fuse that can be connected to: **0AgL (>*0kA) 7) Selective grade: 3 8) Working ambient temperature: *5 - *0°C 9) Enclosed protective class: P*0 (under mounting) *0) Life: a) Electrical: not less of 8,**0 times switching operation b) Mechanical: not less of *0,**0 times switching operation
