2. General information 2.1 Purpose Shihlin's BA series of universal circuit breakers (hereafter refers to as breaker) are available in the circuit of AC 50Hz with rated voltages of 400V, 690V and rated continuous current from 630A to 6300A. The BA offers electric energy distribution and circuit protection, making it the ideal solution for current supply device damages which made by overload, under-voltage, short-circuit and single-phase earthing in distribution network.

4.1.1.2 Short-circuit short time-delay protection features Short time protection has two modes: 1. Inverse time protection: when the fault current exceeds setting current value of de nite time, if it is curve(1 ∼ 5), controller protects according to the curve (1 ∼ 5) of overload long time delay, but the speed 10 times of it. (In other words, it equals to the tenth of the delay tripping time, which computed from the overload long time curve expression.) If it curve6, then calculate the inverse time delay tripping time from the expression of short-circuit shot time delay curve 6 characteristic.

6.3 Mechanical interlocking 6.3.1 Superimposed version and side by side version The interlocking device is installed on the right side of the board of the breaker"s drawer seat. The vertical interlocking is completed by the link in lap- xed breakers. The horizontal interlocking is performed by wire ropes in at- xed breakers. If one of the breakers is in close status, the others interlocked cannot be closed.

9.3.2 How to draw out the breaker Turning handle counter clockwise can draw out the breaker, which is in "connected" position. It needs to pull out the handle to drab out the breaker body from drawer seat when indicator means to "disconnected" position (It cannot be drawled out unless handles has been pulled out).Firmly grasping the handle can remove the breaker from drawer seat.
