General

The TOB9-50LW is a compact, high-performance Wi-Fi smart circuit breaker designed for residential and light commercial applications. It measures key electrical parameters including voltage, current, power, energy, frequency, power factor, leakage current, and ambient temperature. The device supports multiple protection functions: overvoltage, undervoltage, overcurrent, overtemperature, leakage, and current limiting. All parameters can be viewed and adjusted locally on the device or remotely via the companion mobile app.

A unique feature is the external TNC interface for precise ambient temperature measurement, eliminating inaccuracies caused by the device’s own heat generation. The ultra-small form factor is 40% smaller than comparable products. Note: This device switches only the Line (L) conductor.
