CDSB4 mini micro miniature circuit breaker   

Miniature Circuit Breaker(MCB) protect electrical circuits against overload and short-circuit

current. They provide ON-OFF switching easily. MCB is applicable to electric circuits with

rated voltage 230/400V AC, frequency 50/60Hz and rated current up to 100Amp. The

product provides protection against overload and short circuit to electric circuits and

equipments in household and commercial installations. MCB is also used as non-frequent

changeover of electric circuits.

Special tips:

MCB is for non-professional operation by those untrained, and no maintenance is required.

Satisfying conditions and applications as mentioned above. MCB with ”ON-OFF”

indicating devices is considered suitable for isolation function.

Particular devices such as surge protective devices, surge arrester etc are recommended

to install at upstream line to MCB as precaution against potential surge voltage and current

occurring at its power input side.

Appropriate tripping curve being chosen and properly installed. MCB trips and switches off

its protected circuit in case of fault, and thus provides protection against electric shock.

Tripping Curve

B curve:

Recommended for household lighting and control circuits,etc.

Instantaneous tripping current:5In

Instantaneous non-tripping current:3In

Application: provides protection to circuits with low inductive load.

C curve:

Recommended for transfers, inductive loads like florescent lamps.

Instantaneous tripping current:10In

Instantaneous non-tripping current:5In

Application: provides protection to circuits with inductive load or to highly inductive illumination system

D curve:

Instantaneous tripping urrent:20In

Instantaneous non-tripping current:10In

Application: provides protection to circuits with high inductive load or electric distribution system with high surge current
