• Time-delay (minimum of four seconds at five times amp rating) for close sizing. • Current limiting action of the fuse generally affords considerable reduction in bus bracing. • Interrupting rating of 300,000 amperes complies with NEC Sections 110-9 and 230-65 for today's large ...
A short circuit will cause the breaker to open at apredetermined temperature. 断路器是用来保护可能会遇到间歇性过载电流的电路(如电动玻璃升降和大灯电路)。断路器一般都具备复位功能。短路电流会使断路器内部的双金属元件受热从而导致金属片变形,使得断路器内部的触点断开,从而切换回路。 Like fuses, circuit ...
If the breaker does not reset for you after you have removed the appliances from the circuit you will need to contact a qualified electrician. If your circuit cuts out and you haven’t done anything differently and you have removed all known appliances and still can’t get your MCB/RCD to...
However, it should be borne in mind that too pessimistic an approach to the calculations will result in the oversizing of equipment, which in turn will affect the total cost of the device or investment. Figure 1. The general course of the short-circuit current [25]. Short-circuit ...
