1.Model LRR6 series Smart Auto Recloser Application
1.1 LRR6 series smart auto recloser is designed to automatically reclose after the relevant protection device trips when a temporary fault occurs in the power system, so as to improve the reliability of the circuit power supply
1.2 It can be widely used in power grid terminal lines, unattended mobile phone base stations, elevators, air conditioners, smart phones, smart homes, smart factories, new energy vehicle charging piles, etc.Functional Characteristics
2.Model LRR6 series Smart Auto Recloser Characteristics
2.1 It can be matched with MCB or RCD. When the MCB or RCD trips unexpectedly, it does not need to be closed manually, 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 Used in conjunction with circuit breakers and leakage switches to provide overload, short circuit and leakage 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.Description of Automatic, Manual Mode Switches and Mechanical Locksof Smart Auto Recloser
AUTO Mode: Allow remote control (Tuya APP, RS485).
MANU Mode: Remote operation is prohibited
Mechanical Padlock:When the mechanical lock is pulled out, the device will enter the locked state, and the device will not be closed to ensure the safety of on-site maintenance. Press the mechanical lock to restore it.
