Lower voltage circuit breaker mold is used for protection and open/ close of electric circuit of low voltage circuit. ( 1000VAC or less,1500VDC or less). The trip with the calculation of electronic circuit

1. The current flowing in each lower voltage circuit breaker mold is detected by a current transformer (CT). Each phase of the transformed current of the lower voltage circuit breaker mold undergoes full-phase rectification in the rectifier circuit. After rectification, each of the currents of the lower voltage circuit breaker mold are converted by a peak-conversion and effective –value conversion circuit.

2. When over current or short circuit current flows, each time-delay lower voltage circuit breaker mold generates a time delay corresponding to the largest phase. The trigger circuit outputs a trigger signal. The trip coil is excited, operating the switching mechanism to trip.

Especially, electronic type is very convenient for cooperation, as the rated current value is adjustable. By using optional setting device. Simple operation check and monitoring/setting of the characteristic setting value of the lower voltage circuit breaker mold are available.

The various lower voltage circuit breaker mold monitoring and the high level of energy management systems are made. Each one of the breakers,MCCB ,ELCB or the earth leakage alarm breakers, in combined with a MDU.The MDU,measuring display unit ,means a device having functions of measure ment,indication,or transferring the measuring data of the lower voltage circuit breaker mold

Root sino lower voltage circuit breakers mold create a future of the electrical equipment. For over these 15 years Root sino lower voltage circuit breaker mold meet the need of the market. Including the WS-V series equipped with a new breaking technology, Root sino lower voltage circuit breaker mold have various lineups depending on the electric power market and the machinery.

Various connection methods such as Front connection type, rear connection type, plug-in –type, etc. are available. You can order according to your needs. Front connection type of lower voltage circuit breaker mold is a standard type connectable from the front. Rear connection type is which the lower voltage circuit breaker mold wiring from the backside of the circuit breakers is available. Plug-in type is inserting the main body into the plug-in terminal block of the lower voltage circuit breaker mold.
