As a leading manufacturer from Jinhua Dika Electrical Equipment Co., Ltd. (established in Zhejiang, China), we are proud to introduce our 380V 4 Pole Smart MCB Breaker Switch with Earth Leakage Protection. This innovative circuit breaker combines traditional overcurrent and earth leakage protection with advanced IoT remote control capabilities, offering unmatched convenience and safety for modern households and commercial buildings. With three rated current options (63A, 80A, 100A) and a robust plastic case, it is designed to meet diverse electrical distribution needs while ensuring real-time monitoring and switching via smartphone or cloud platform.
Our factory specializes in electrical equipment and has an annual export value of US$1 million to US$1.5 million, serving global markets including North America, Europe, Southeast Asia, and Oceania. The Smart MCB is certified under ISO9001, ISO14000, and other international standards (certifications listed in our company profile), guaranteeing reliable performance and compliance with safety regulations. Whether you are a distributor, contractor, or facility manager, this product provides a cost-effective solution for smart home energy management and leakage protection.
Key Features & Technical Specifications
- 4-Pole Design: Suitable for three-phase (380V) systems with neutral line, ensuring complete overcurrent and earth leakage protection for all phases.
- Earth Leakage Protection: Residual current detection (RCD) with adjustable sensitivity (typically 30mA, 100mA, 300mA – optional). Trips instantly to prevent electric shock and fire hazards.
- Smart IoT Remote Control: Built-in Wi-Fi module enables remote ON/OFF switching via dedicated app (compatible with iOS & Android). Supports scheduling, energy monitoring, and cloud integration (e.g., Alexa, Google Home – check compatibility).
- Rated Current Options: Available in 63A, 80A, and 100A, with thermal-magnetic trip curve (C or D curve – customizable). Meets overcurrent protection for various loads.
- Flame-Retardant Plastic Case: High-impact polycarbonate shell with IP20 rating (optional IP40). Excellent insulation and durability.
- DIN Rail Mounting: Standard 35mm DIN rail installation, compatible with most distribution boards. Compact size (4 modules / 72mm).
- Local & Remote Status Indication: LED indicators for power, trip, and connectivity. Audible alarm optional.
- Manual Override: Traditional toggle switch for local operation even without internet connection.

Frequently Asked Questions (FAQ)
-
Q: Can this smart MCB be used as a main switch for a house?
A: Yes, with 380V/63A–100A ratings and 4-pole design, it is suitable as a main breaker for three-phase residential or small commercial supply. Ensure your system neutral is available. -
Q: Does it require a neutral wire to function?
A: Yes, the 4-pole configuration includes a switched neutral (N) pole. For earth leakage detection, a neutral connection is necessary. The IoT module requires a small power supply from the line side. -
Q: Is the earth leakage sensitivity adjustable?
A: The standard model offers selectable sensitivity (30mA, 100mA, 300mA) via internal DIP switch. Please specify your requirement when ordering. Custom thresholds available for bulk orders. -
Q: What app do I need for remote control? Is it compatible with Alexa/Google Home?
A: We provide a dedicated app (say, “Dika Smart” or “Smart Life” based on platform). It works with iOS and Android. Integration with Alexa or Google Assistant may require additional skill setup – please contact our tech support for details. -
Q: What is the breaking capacity? Is it safe for industrial use?
A: The breaking capacity is 6kA at 380V, which meets IEC 60898-1 for residential and light commercial applications. For higher fault currents (e.g., 10kA), we can customize upon request, but industrial heavy-duty usage may require a different series. -
Q: How long does it take to ship?
A: Sample orders usually ship within 5–7 working days. Bulk orders (≥100pcs) need 15–20 days depending on configuration. We ship via sea or air from our ports: Shanghai, Ningbo, Tianjin, or Guangzhou. -
Q: Do you offer OEM/ODM service? Can I have my logo on the product?
A: Yes, we can customize the packaging, labeling, and even the user interface language. Minimum order quantity for OEM is typically 500pcs. Contact our sales for a detailed quote. -
Q: What kind of warranty do you provide?
A: We provide a 12-month warranty from the date of shipment against manufacturing defects. Extended warranty or insurance is negotiable for large projects. Technical support is available throughout the product life.
