Miniature Circuit Breaker

Meba b type mcb MB1316C

Meba b type mcb MB1316C, this miniature circuit breaker is used in lighting distribution system or motor distribution system for protection overload and short-circuit in the system. The product is neuteric in structure, light in weight, reliable and excellent in performance. It has high breaking capacity, can trip quickly, and its case and items are adopted by high fire-resistant and shockproof plastics. The product, with long life, is mainly used in AC 50Hz/60Hz single-pole 230V or two, three, four pole 400V circuit for overload and short-circuit protection as well as for un frequent on-and-off switching electric equipment and lighting circuit in normal case. The products comply with IEC 60898.

Some items for your reference when selecting the device:

a)The earthing systems(TNS,TNC)

b)Short-circuit of the specific power system, which must always be less than the breaking capacity of this device

c)The rated voltage

d)Tripping curves:

  • B curve (3-5In) —- protection for people and big length cables in TN and IT systems (lights or socket circuits etc.)
  • C curve (5-10In) —- protection for resistant and inductive loads with low inrush current (groups of bulbs, motors etc)
  • D curve (10-14In) —- protection for circuits with high inrush current (transformers, double-pole motors, motors with heavy start etc)
