WENZHOU, CHINA — September 16, 2026 — ELECO, a global leader in intelligent electrical protection and control solutions, today announced the launch of its next-generation EWG-4 Smart Circuit Breaker. The device integrates adjustable overvoltage, undervoltage, residual current, and electromagnetic short-circuit protection with advanced IoT connectivity, enabling remote App control, voice assistant compatibility, and real-time energy monitoring. Designed for smart homes, commercial buildings, and industrial Distribution Panels, the EWG-4 sets a new benchmark for safety and intelligence.
1. Comprehensive Multi-Layer Protection
The EWG-4 goes beyond conventional breakers by offering fully adjustable protection thresholds to match specific application requirements:
- Overcurrent Protection: 1A – 63A (adjustable)
- Undervoltage Protection: 76V – 240V (adjustable)
- Overvoltage Protection: 220V – 265V (adjustable)
- Residual Current (Leakage) Protection: 10 – 100 mA (adjustable)
Additionally, the unit features a built-in electromagnetic short-circuit trip mechanism that clears faults within milliseconds, significantly reducing the risk of fire and equipment damage.
2. Full-Scenario Smart Control & Connectivity
The ELECO EWG-4 supports three control modes: local manual operation, mobile App remote control, and voice commands. It is certified for seamless integration with Amazon Alexa and Google Home, allowing users to switch circuits or check status using simple voice prompts.
Other smart capabilities include:
- Scheduling & Countdown: Set timers for appliances to save energy and increase convenience.
- Energy Metering: Real-time tracking of current, voltage, power, frequency, and temperature for better energy management.
- Multi-Protocol Communication: Supports Zigbee, LoRa, SigMesh, RS485, and RJ45 to fit diverse network architectures.
