Miniature Circuit Breakers (MCB)

To protect conductors against overloads and short circuits current in the electrical distribution system.
Designed for use by unskilled person.
Suitable for use in eletrical system with rated voltage up to 440V AC, frequency 50/60Hz.
Use in domestic, commercial and industrial installations.

Selection for suitable triping curve

Choose the appropriate tripping curve for proper installation and better protection.

B curve

Instantaneous tripping: 5ln
Instantaneous non-tripping: 3ln [3ln ≤ 0.1s < 5ln]
Application: provide protection for circuits with low inductive load.

C curve

Instantaneous tripping: 10ln
Instantaneous non-tripping: 5ln [5ln ≤ 0.1s < 10ln]
Application: provide protection for circuits with inductive load or highly inductive lighting fittings.

D curve

Instantaneous tripping: 20ln
Instantaneous non-tripping: 10ln [10ln ≤ 0.1s < 20ln]
Application : provide protection for circuits with high inductive load or electrical system / equipment with high surge current.
