CJB1 18mm Width 1P 2P 3P 4P Plug in Circuit Breaker 6ka Single Phase

1. Application:For protecting cables and equipments against overload and short circuit.

2. General rules for choosing MCB.

2.1 Technical data of the network at the point considered:

The earthing systems, short-circuit current at the circuit breaker installation point, which must always be less than the breaking capacity of this device,network normal voltage.

2.2 There are 3 curve characteristics for magnetic operation:

B curve (3-5 In) protection and control of the circuits against length cables in TN and IT systems.

C curve (5-10 In) protection and control of the circuits against overloads and short-circuits; protection for resistive and inductive loads with low inrush current.

D curve(10-20 In) protection and control of the circuits against overloads and short-circuits; protection for circuits which supply loads with high inrush current at the circuit closing (LV/LV transformers, breakdown lamps).

3. CJB1 is of high current limiting performance to limit the destuction energy due to short circuit to the greatest extent.
