How to see the secondary wiring diagram of the electrical wiring diagram?

A wiring diagram of an electrical wiring diagram usually only indicates the delivery and distribution of electrical energy, and does not indicate the control, monitoring, measurement, indication, and protection of the electrical circuit. A wiring diagram used to reflect the control, monitoring, measurement, indication, and protection of the electrical circuit. It is called a secondary wiring diagram. Or called the secondary wiring diagram. An appliance directly connected to the secondary wiring is called a secondary device or a secondary component.

Â Â Â Â The secondary wiring diagram usually only draws a component, a parameter, or a function of a unit in a wiring diagram. According to this feature, the secondary wiring diagram can be read smoothly. Figure 1-10 shows the secondary wiring diagram of the current measurement of the current transformer 1TA [current parameter] of the power input unit in Figure 1-9. The ammeter PA in the figure is a secondary component used to indicate the current flowing in the three-phase line.

KNB6-40 Miniature Circuit Breaker

KNB6-40 Mini Circuit breakers, also named as the air switch which have a short for arc extinguishing device. It is a switch role, and also is a automatic protection of low-voltage electrical distribution. Its role is equivalent to the combination of switch. Fuse. Thermal Relay and other electrical components. It mainly used for short circuit and overload protection. Generally, According to the poles, mini Circuit breaker can be divided into 1P , 1P+N , 2P, 3P and 4P.
