Main functions of xi 'an zw7-40.5 C outdoor intelligent vacuum circuit breaker
0-band UPS function
UPS function; Ac power loss can be divided into 50 times or more to ensure normal operation within 48 hours.
Time limit protection function
The time limit protection mode is conducted in accordance with the traditional three-phase current protection mode (speed limit, speed limit and overcurrent).
2. Reclosing function
The function of multiple reclosing can be performed according to the preset number of times.
3. Hand contact fault function
When manually closed, failure occurs, the controller is immediately disconnected and not reclosing.
4 anti-surge function
When the current is less than the current value set by the user, the user's setting time is delayed to prevent the current. If the current is greater than the current value set by the user, the user's setting time is not prevented.
5 operating functions
The coincidence unit controller provides the operation function of the control panel, the operation function of the remote control and the operation function of remote control and remote host.
6 communication function
The product can communicate with mobile phone to realize remote control. Thereby realize telemetry, telecontrol, telecontrol, telecontrol four remote functions.
7 LCD display function
