WTB2-80 WiFi Smart Circuit Breaker for Home Automation and Remote Monitoring
Pair the WTB2-80 WiFi with smart home panels, vacation rentals, small business distribution and remote monitoring setups that want breaker control on a phone.
WTB2-80 is a WiFi-enabled smart circuit breaker that adds remote control, residual current protection and energy metering to standard DIN-rail distribution.
WiFi connectivity
The built-in WiFi module connects directly to the home router, so the breaker works with the app for remote switching, schedules and alerts without extra gateway hardware.
Residual current protection
AC type residual protection covers 30mA, 50mA, 100mA and 300mA settings, with adjustable leakage and shock protection for circuits of different sensitivity.
Energy metering
Per-circuit monitoring reports current, voltage, leakage value, energy consumption, frequency and temperature, which supports usage analysis and fault detection.
Ratings and tripping
Rated current spans 32A, 40A, 50A, 63A and 80A in 2P (AC230V) and 4P (AC400V) versions, with B, C and D trip characteristics and 6kA breaking capacity.
Durability and environment
Mechanical lifespan reaches 20,000 operations and electrical lifespan 10,000 operations. Wiring capacity is 25mm², operating temperature spans -25℃ to +65℃, and protection level is IP20.
