2P,4P Smart 4G RS485 (RCBO) Circuit Breaker
The 2P and 4P Smart 4G RS485 RCBO Circuit Breaker provides overload, short-circuit, and earth leakage protection with...
Product Overview
What This Model Does
The 2P and 4P Smart 4G RS485 RCBO Circuit Breaker provides overload, short-circuit, and earth leakage protection with remote monitoring and control via 4G and RS485. It monitors real-time voltage, current, and energy consumption on the output side, automatically cuts power during faults, and performs automatic reclosing when the line returns to normal. Designed for unattended sites, it enables remote switching, fault inquiry, and energy data collection without requiring a local gateway.
Key Benefits
- Automatically restores power after a fault without site visits, ideal for remote or unattended locations
- Monitors real-time voltage, current, and energy use to support load analysis and energy management
- Remote control over 4G and RS485 allows switching and fault checking from any location with network access
- Maintains mechanical protection functions (overload, short-circuit, earth leakage) independent of network status
- No need for a local gateway—4G communication operates directly over cellular networks
- Supports integration into smart monitoring systems via RS485 and 4G for data logging and remote diagnostics
Who It Is For
- Electrical wholesalers adding a smart monitoring and control layer to their conventional RCBO range
- Panel builders integrating remote monitoring into distribution boards for industrial or commercial projects
- Solar EPC contractors deploying smart breakers in off-grid or remote solar installations
- Facility managers responsible for multiple sites with limited on-site staff
- Smart building and energy management system integrators sourcing remote-controlled RCBOs with metering
Problems It Solves
- An engineer must travel to a remote site to manually reset a tripped breaker after a temporary fault
- Energy consumption per circuit cannot be measured without adding separate meters or data loggers
- Faults go undetected or unresolved in unattended locations due to lack of remote visibility
- Manual switching is required for scheduled or emergency power control, increasing operational risk
- Existing monitoring systems require a local gateway, increasing complexity and cost
Application Scenarios
- Remote solar power installations where breakers are inaccessible and need automatic reset after fault clearance
- Industrial sites with distributed equipment where manual reset trips are impractical
- Water pumping stations and irrigation systems that require remote on/off control and energy tracking
- Smart buildings or campuses where energy consumption per circuit must be monitored and reported
- Unattended infrastructure such as street lighting, telecom base stations, or rural substations
Technical Features
How It Is Built
- Real-time monitoring of voltage, current, and energy consumption with high precision
- Automatic reclosing after fault recovery in unattended environments
- Remote switching and fault inquiry via 4G wireless and local RS485 communication
Materials and Construction
- Silver-alloy contacts with a thermal-magnetic trip mechanism and earth leakage detection
- Integrated 4G and RS485 communication module inside the breaker body
Quality Control
- 4G and RS485 communication tested for remote control and data transmission
- Insulation and dielectric withstand test performed before packing

Manufacturing Process
- Moulding and machining of the breaker housing and internal carriers
- Assembly of the thermal-magnetic trip unit, earth leakage sensor, and contact system
- Fitting and firmware loading of the 4G and RS485 communication module
- Calibration of the trip characteristic against the Type C curve and leakage threshold
- Routine dielectric and operation testing before packing
Customization Options
- Pole count supplied as 2P or 4P from the same series
- ODM branding on housing print and packaging
- Packaging and carton marking to the buyer's own specification
Comparison
How It Compares
| Conventional RCBO | Adds remote monitoring, automatic reclosing, and energy metering at a higher unit cost |
|---|---|
| RCBO plus separate 4G data logger | One device instead of two, though the 4G module is built-in and not external |
| Zigbee smart RCBO | No need for a local gateway—4G works directly over cellular networks |
| RS485-only smart RCBO | Adds 4G capability for remote access without relying on a local control panel |
Use Guide
- Switch on manually and confirm the breaker holds under normal load before enabling remote functions
- Configure the 4G module with a valid SIM card and network settings before first use
- Connect via RS485 or 4G to a central monitoring system or SCADA platform for remote control and data access
- Set up automatic reclosing parameters in the communication interface to suit site conditions
- Keep the manual handle accessible so the circuit can always be isolated on site

FAQ
Questions About the 2P,4P Smart 4G RS485 (RCBO) Circuit Breaker
Does it still protect the circuit if the 4G network is down
Yes. Overload, short-circuit, and earth leakage protection are mechanical and operate independently of the network. Only remote control and monitoring require connectivity.
