Note Without current release components, N-Pole is alwaus at making status, not makes and breaks with other three poles; Without current release components, N-Pole makes with the other three poles(NPole first makes then breaks);

Specifications

Application The Changeover Switch can switch on, Load and break the circuit under normal conditions,usingas Switch Disconnectors. Standard: IEC 60947-3 Circuit Diagram Overall and Mounting Dimensions(mm)

Feature Feature 1: Current limiting ability Limiting the rise of short circuit current of circuit. The peak short circuit current and I2t power are much lower than the value expected. U shape fixed contact design The U shape fixed contact design achieves the technique of pre-breaking: When the short circuit current pass through the contact system, there are forces that repel each other on the fixed contact and moving contact. The forces were produced with short circuit current synchronous and...

Application YC9VA voltage and current display relay used in administrative, industrial and residential buildings and has the function of protecting single-phase lines: Undervoltage protection; Overvoltage protection; Working under voltmeter mode. Operation and Installation Functions When a voltage is applied to the device, the digital indicator will display the current value of the voltage in the network. A flashing light indicates that there is no voltage on the output of the device. If th...
