Miniature Circuit Breakers (mcbs)

Safety

Miniature circuit breakers meet the characteristic tripping curves B and C, according to NBR NM 60898 and NBR IEC 60947-2 standards.

Flexibility

We have single-pole, two-pole and three-pole distribution bus, and padlock as accessories

It is possible to use auxiliary and alarm contact blocks.

It also has a free trip mechanism, where the trip does not depend on the position of the handle, and indication of the circuit breaker status.

Tripping Characteristic Curves

The main characteristic of the miniature circuit-breaker of the B curve is the instantaneous trip for currents 3 to 5 times above the rated current. Therefore, they are applied mainly in the protection of circuits with resistive characteristics or with great cable lengths involved.

Curve C

The characteristic of the miniature circuit-breaker of the C curve is the instantaneous trip for currents 5 to 10 times above the rated current. Therefore, they are used for the protection of circuits with installation of inductive loads.
