Model LRR6 series Smart Automatic re-closing circuit breaker characteristics
1.1 It can realize remote opening and closing control, timing tasks, and obtain the current switch status through wifi APP.
1.2 Built-in multiple re-closing times, continuous closing failure within a certain period of time can send an alarm signal through the LED indicator light or APP. (for specific time and frequency, please refer to the parameter table) 1
1.3 Re-closing times and delay time can be set up and adjusted as per request.
1.4 With manual/automatic selection switch and mechanical lock function.
1.5 Used in conjunction with circuit breakers and leakage switches to provide overload, short circuit and leakage protection.
1.6 The working status is indicated by LED etc.
2.1 When Smart Automatic reclosing circuit breaker trips unexpectedly, it does not need to be opened and closed by manual operation, reducing manual maintenance costs, and timely troubleshooting to improve efficiency.
2.2 It can realize remote opening and closing control, timing tasks, and obtain the current switch status through wifi or a platform with RS485 connection.
2.3 Built-in multiple reclosing times, continuous closing failure within a certain period of time can send an alarm signal through the LED indicator light or APP. (for specific time and frequency, please refer to the parameter table)
2.4 Reclosing times and delay time can be set up and adjusted as per request.
2.5 With manual/automatic selection switch and mechanical lock function.
2.6 The smart automatic reclosing circuit breaker to provide overload, short circuit ,leakage, over-voltage, under-voltage protection.
2.7 The working status is indicated by LED etc.

Remark |
The Wifi-type smart module needs to configure the network when it is used for the first time, and the Tuya App needs to be downloaded and installed on the mobile phone. The smart module and the mobile phone are required to be matched under the same wireless network. If the network device is replaced, the smart module needs to reconfigure the network. |
4.How Auto-Recloser Works
4.1 In the auto state, after the fault trips and meets the closing requirements, the equipment will reclose according to the time set by the reclosing switch.
If the device fails to close within the specified time, the device will no longer reclose, and at the same time output an alarm signal (via Tuya App or RS485). In this state, opening and closing can be achieved through remote control or manual control.
4.2 Auto reclosing successful
If the switch is successfully closed, it will no longer trip within the specified time (60 seconds for EKR3-RS485), which is defined as successful switch-on. After successful switch-on, the number of frequency the device has been reclosed is automatically cleared, and the counter restarts count.
(Any opening and closing behavior controlled by humans will clear the number of reclosing times)
4.3.Automatic, Manual, Padlock mode
Turn [Auto/Manu] to the automatic mode Auto, manually open the circuit breaker, the default is fault trip, and the device will start to automatically reclose according to the program setting.
4.4Turn [Automatic/Manual] to the manual mode Manu, the automatic reclosing and remote control functions will be invalid, and the brake can be opened or closed manually.
4.5 Pull out the mechanical padlock on the module, and the device will enter the locking padlock mode to achieve local locking, ensuring that operators can perform maintenance work in a safe state.
