Mininature Circuit Breaker L7 type

 

 

 

Applications:

 

L7 63a mini circuit breaker 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 IP20), high breaking capacity, reliable sensitive action, convenient multi-pole assembling and long life. They are mainly adapted to the circuit of AC 50Hz, 230V in single-pole, 400V 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 EN60898 (IEC898), GB10963-99
2) Rated voltage : 230V/400V, 50/60Hz
3) Rated breaking capacity: 10kA IEC898 (0.5 - 63A), 15kA IEC947-2 (0.5 - 63A)
4) Short circuit breaking capacity of DC: max. 48V (KL7, 10kA) single-pole,
max. 250V (KL7-DC, 6kA) single-pole
5) Performance: C, D characteristic curve
6) Max. fuse that can be connected to: 100AgL (>10kA)
7) Selective grade: 3
8) Working ambient temperature: -5 - 40°C
9) Enclosed protective class: P40 (under mounting)
10) Life:
a) Electrical: not less of 8,000 times switching operation
