Smart dual-relay day/night circuit breaker with temperature sensor, 100A, Wi-Fi system, Tuya app
JJMVPD-100LW
Integrated Digital Protection Circuit Breaker 100A - Engineering Edition for Full Line Isolation
Why is the Double Relay Breaker the perfect solution for your local grid?
Unlike traditional breakers that only cut the live wire, this breaker is designed with a Double Relay that cuts both the live and neutral wires simultaneously when a fault occurs. This feature provides absolute protection against reverse currents and the risks of neutral voltage spikes common when switching between the national grid and private generators, ensuring complete galvanic isolation for your home.
Advanced Compressor Protection
Provides an adjustable power-on delay of up to 500 seconds, ensuring gas pressure equilibrium in air conditioners before power is restored, making it the most efficient solution to prevent motor burnout.
NTC Thermal Monitoring
Equipped with an external thermal probe that monitors the temperature of the main cables in real-time. The breaker proactively disconnects power if any heat spike is detected due to loose connections.
Smart Control & Energy Audit
Full management via Smart Life and Tuya apps. Monitor voltage, current, and temperature in real-time with the ability to schedule operation to balance generator and grid loads.
Prepaid System
Supports a "Prepaid" function to set specific energy quotas, making it ideal for residential complexes or managing private generator consumption with high metrological accuracy.
