Introduction

• RP02RH series is a class C smart Miniature Circuit Breaker with a Power Meter based on LoRaWAN open protocol. It can monitor the status of all external circuit breakers in real-time. (connect up to 9 poles). When the power line is abnormal (such as undervoltage, overvoltage, overload, leakage, etc.), the system will automatically give an early warning, alarm, and power off to prevent electrical fire to the greatest extent. At the same time, it can periodically monitor the temperature, electric quantity, current, voltage, power, leakage current, circuit breaker status and other data information of all external circuit breakers and report to the gateway platform. With the system, it can be controlled remotely and regularly, can be switched regularly, and can automatically conduct monthly leakage self-inspection, with limited power and electric quantity. It has the function of local self-inspection and reports the detection information to the gateway platform to make the hidden danger disappear.
• At the same time, it can be switched to serial port transparent transmission mode and can reply to 128 bytes of data at most (depending on the current communication rate). Serial port transparent transmission only supports RS-485 protocol.

The number of poles corresponding to each circuit breaker type:

For example, a LoRa / LoRaWAN Radio Module can connect to:

• (a) 4 x 1PN/1PNL/2P (8 poles in total)
• (b) 2 x 3PN/3PNL/4P (8 poles in total)
• (c) 2 x 1PN/1PNL/2P + 1 x 3PN/3PNL/4P (8 poles in total)

LoRa Wireless Technology:

• LoRa is a wireless communication technology famous for its long-distance transmission and low power consumption.
• Compared with other communication methods, the LoRa spread spectrum modulation technique greatly extends the communication distance. It can be widely used in any use case that requires long-distance and low-data wireless communications. For example, automatic meter reading, building automation devices, wireless security systems, and industrial monitoring.
• It has features like small size, low power consumption, long transmission distance, strong anti-interference ability, and so on.

LoRaWAN:

• LoRaWAN uses LoRa technology to define end-to-end standard specifications to ensure interoperability between devices and gateways from different manufacturers.
