Product Description

STB3-125 WiFi Metering Smart MCB (WiFi Remote Control Intelligent IoT Controllers) are upgraded on the basis of traditional
circuit breaker power distribution equipment.

Through the Internet of Things technology, data acquisition and processing of power distribution equipment, equipment status
monitoring and early warning alarms and other intelligent management can be realized. Closing, when the circuit breaks down,
it protects the electrical appliances in use and avoids damage to the electrical equipment.

In the construction of smart grid, intelligent power distribution is an indispensable and important component. The intelligent features of intelligent power distribution can not only greatly reduce the difficulty of grid operation management, but also control and relieve personnel. Stress is especially important.

The products realize accurate display of current, voltage and power. Let the current change, voltage fluctuations, load power consumption more clearly. It is equipped with a power statistics function, supports billing amount setting, quickly queries historical data, and controls power consumption status.

With an impeccable protection mechanism, it provides peace of mind protection. The circuit breaker is equipped with a threshold protection setting. When the electrical parameter in the line exceeds the set value, the product immediately enters the protection state. Structurally, the thermal overload protection is firm and the agile response of the transient protection upholds all the features of the original circuit breaker. Powerful leakage protection function, extremely fast tripping action, effectively protect personal safety. And through sharing, the distribution of permissions and multi-channel control.
