LS Miniature Circuit Breaker BK63N 1P B1A

Introduction: LS power miniature circuit breaker BK63N 1P B1A can turn on, carry and break the current under normal circuit conditions, and can also turn on and carry a certain time and breaking current under the specified abnormal circuit conditions.

LS Power BK63N 1P B1A

Features:

1. Specify the desired welding current. The required welding current is recognized primarily based on the welding data and welding process. The robot controls the indication of the normal welding current range.

In civil building planning, low-voltage circuit breakers are mainly used for overload, short circuit, overcurrent, loss of voltage, undervoltage, grounding, leakage, automatic switching of dual power supplies and maintenance and operation of infrequent start of the motor.

1) The additional voltage of the miniature circuit breaker of BK63N 1P B1A product model should not be less than the additional voltage of the line;

2) The additional current of the miniature circuit breaker and the additional current of the overcurrent tripper of the BK63N 1P B1A product model shall not be less than the accounting current of the line;

3) The additional short-circuit breaking of the small circuit breaker of BK63N 1P B1A product model can not be less than the largest short-circuit current in the line;

4) BK63N 1P B1A product model selection distribution circuit breaker needs to consider the short delay short circuit on-off in order to cooperate with the delay maintenance level;

5) BK63N 1P B1A product model miniature circuit breaker undervoltage tripper extra voltage is equal to the extra voltage of the line;

6) When the BK63N 1P B1A product model is used for motor maintenance, the starting current of the motor should be considered when selecting the circuit breaker and make it not operate at the starting time; For planning and accounting, please refer to the "Industrial and Civil Distribution Planning Manual";

7) The selection of circuit breakers should also consider the selective cooperation between circuit breakers and circuit breakers, circuit breakers and fuses.

Planning Essentials

(1) The cooperation between the circuit breaker and the circuit breaker should consider the instantaneous trip device action value of the upper circuit breaker, which should be greater than the maximum expected short-circuit current at the outlet end of the lower circuit breaker.

(2) When the short-circuit current is greater than or equal to the setting value of the instantaneous tripper, the current-limiting circuit breaker will trip within a few milliseconds, so the circuit breaker should not be used to complete the selective maintenance requirements of the subordinate maintenance appliances.

(3) When the circuit breaker with a short delay is set at the largest delay, its on-off can be reduced, therefore, in the selective maintenance circuit, the short-delay on-off of the selected circuit breaker should meet the requirements.

(4) It should also be considered that the short-circuit delay returnable characteristic of the upper circuit breaker should not intersect with the action characteristic curve of the lower circuit breaker, and the short-delay characteristic curve and the instantaneous characteristic curve should not intersect.

(5) When the circuit breaker and fuse are used together, the cooperation between superiors and subordinates should be considered, and the ampere-second characteristic curve of the circuit breaker should be compared with the ampere-second characteristic curve of the fuse, so that it can be maintained selectively in the case of short-circuit current.

(6) When the circuit breaker is used for the maintenance of the distribution line, it is advisable to choose a circuit breaker with a long-delay action overcurrent tripper, and when a single-phase grounding short circuit occurs at the end of the line, the short-circuit current shall not be less than 1.5 times of the setting current of the instantaneous or short-delay overcurrent tripper of the circuit breaker.
