Miniature circuit breakers and molded case circuit breakers are all circuit breakers. The working principle is the same. The difference is that:
1. The installation method of the miniature circuit breaker is the rail installation, and the molded case circuit breaker is screw installed;
2. The maximum current rating of the miniature circuit breaker is within 63A, and the current rating of the molded case circuit breaker is up to 2000A.
Miniature circuit breaker: electrical parameters
a. Meet electrical standards: EN0898 (IEC898), GB10963;
b. rated voltage (Ue): 230/400V; 50/60Hz;
c. rated short-circuit breaking capacity Icu: 10kA IEC898 (1~63A);
d. DC short-circuit breaking capacity: maximum 48V (S-5SJ4..., 10kA) single pole maximum 250V (S-5SJ4-DC, 6kA) monopole
e. Tripping characteristics: B, C, D characteristic curves
f. Maximum edge fuse: 100A gL (>10kA)
g. Selective level: 3
h. Working environment temperature: -5 to +40 ° C
i. Shell protection level: IP40 (after installation)
j. Life: electrical, no less than 8000 times of on-off operation machinery, no less than 20,000 times of on-off action
