Meba breakers MBI236C
Product Description
Meba breakers MBI236C , this mini circuit breaker is mainly suitable for overload and short circuit protection. It is especially used for illumination and distribution in industry and commerce.It is of pleasing outlook & high breaking capacity etc.The frame and parts adopt plastics of light weight, reliable performance, high inflammable resistance and shock resistance for long service life. It is mainly used for overload and short circuit protection within the circuit of AC 50/60Hz,rated voltage of single pole up to 230V, two, three or four pole up to 400V. It can also be used for an un-frequent switch over of the circuit and illumination under normal conditionMeba breakers MBI236C
Technical parameters:
| Rated current(A) | Pole | Rated voltage (V) | Breaking capacity (A) | Electrical life(times) | Mechanical life (times) |
| 1,2,3,4,6,10,16,20,25,32,40,50,63 | 1,2,3,4 1P+N | 240/415 | 6000 | 8000 | 10000 |
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)
The over-current tripping unit protection feature:
| Sequence NO . |
Release | Test current I/In |
Start state | Tripping time |
