Why Choose Our Smart Earth Leakage Breaker?
Our 380V 4 Pole Earth Leakage MCB is engineered to deliver superior protection and intelligent control. The built-in remote control allows operators to turn the breaker on/off from a distance, reducing manual intervention and improving safety in hazardous areas. The IoT module (available as an option) enables real-time monitoring of current, leakage, and trip events via cloud platforms, making predictive maintenance and energy management seamless. The compact plastic case design ensures easy installation within standard distribution boards, while the high breaking capacity ensures reliable performance under fault conditions.
- Enhanced Safety: Combined earth leakage, overload, and short-circuit protection in a single device, reducing panel space and wiring complexity.
- Smart Connectivity: Integrate with building management systems (BMS) or smart home hubs via Modbus or MQTT; supports remote status check and alarm notifications.
- Durable Construction: Plastic case made from high-grade flame-retardant material, tested for 850°C glow wire compliance, ensuring fire safety.
- Flexible Configuration: Adjustable leakage sensitivity and time delay (S-type) for selective coordination in distribution systems.
- Cost-Effective: All-in-one solution eliminates the need for separate MCB and RCCB, saving installation and material costs.

Frequently Asked Questions (FAQ)
-
Q: What is the difference between this breaker and a standard MCB+RCCB combination?
A: This device is an integrated earth leakage MCB (RCBO), combining overload, short-circuit, and earth fault protection in one unit. It saves space and reduces wiring, while also offering remote control and IoT features not available in separate devices. -
Q: Can I use this breaker for single-phase applications?
A: This model is designed for 4-pole three-phase systems (3P+N). For single-phase applications, we recommend our 2-pole version (available separately). Please consult with our sales team for the right product. -
Q: Does the remote control work without internet?
A: Yes, the built-in RF remote control operates locally within a range up to 100 meters (line of sight) without internet. IoT features require a gateway and internet connection for cloud monitoring. -
Q: What communication protocols are supported for IoT?
A: We support Modbus RTU (RS485) and MQTT via an optional Wi-Fi or Ethernet gateway. Custom protocols can be developed upon request for large orders. -
Q: Is the leakage sensitivity adjustable?
A: Yes, the sensitivity can be set to 30mA, 100mA, or 300mA using a DIP switch on the front panel. Time delay (S-type) is also configurable for selective coordination. -
Q: What certifications does the product have?
A: The product is designed to comply with IEC 60947-2 and IEC 61008-1 standards. Specific certifications like CE or CB are available upon request and subject to testing. Please contact us for certification details for your target market. -
Q: Can I get a sample before bulk order?
A: Yes, we offer samples for evaluation. You can order one unit with our standard pricing, or we can arrange a sample for qualified inquiries. Sample lead time is 3-5 working days. -
Q: What is the warranty period?
A: We provide a standard 18-month warranty against manufacturing defects. Extended warranty options are available upon request.
