Product Overview

What This Model Does

The IoT Smart Circuit Breaker S8001 series is a smart breaker designed for internet-connected power management and energy monitoring. It integrates electronic control with traditional mechanical protection, enabling remote switching, timing tasks, and local mode selection. Built for 220V/380V AC systems, it supports rated currents from 32A to 125A with Type C or D instantaneous trip characteristics. The device includes an integrated WiFi module for remote control via app, and operates independently of the network for core protection functions. It is suitable for use in smart buildings, industrial panels, and distributed energy systems where remote monitoring and control are required.

Key Benefits

Enables remote on/off control of circuits via smartphone app without physical access to the panel
Supports scheduled timing tasks for load automation without external timers or PLCs
Maintains mechanical short-circuit protection and isolation functions regardless of network status
Allows local operation and mode switching when remote control is unavailable
Uses a built-in WiFi module for direct network connection, reducing need for external gateways
Supports both Type C and Type D instantaneous trip characteristics for different load types

Who It Is For

Electrical wholesalers expanding into smart protection devices
Panel builders integrating remote control into distribution boards
Facility managers overseeing multiple sites with limited on-site staff
Smart home and building automation integrators requiring app-controlled breakers
Solar and energy management contractors deploying remote monitoring in off-grid systems

Problems It Solves

An engineer must travel to site to reset a tripped breaker after a fault or scheduled event
Manual timers and contactors add complexity and extra wiring for scheduled switching
No remote visibility or control over circuit status in distributed or remote installations
Lack of integration between power protection and building automation systems
Inability to monitor or manage energy use across multiple circuits without additional meters

Application Scenarios

Industrial equipment powered down during non-working hours via scheduled app control
Remote reset of tripped breakers in unattended solar inverters or pump stations
Smart building systems automating lighting and HVAC based on time-of-day schedules
Energy monitoring and load shifting in commercial facilities using app-based data logging
Remote access to circuit status for maintenance teams managing multiple sites

Comparison

How It Compares

Conventional MCB	Adds remote control and timing functions but requires power and network for smart features
MCB with external timer and contactor	One device instead of three, though logic resides in app rather than panel
Zigbee smart breaker	No gateway required for WiFi version, but depends on local router availability
