NDB5E-40/80

The NDB5E-40 and NDB5E-80 IoT Miniature Circuit Breakers are intelligent devices featuring automatic opening and closing, over/under voltage protection, residual current protection, energy metering, temperature monitoring, overload time-delay protection, scheduled switching, power limiting, and three-phase unbalance protection. They enable communication management via PC or mobile APP, primarily for energy metering and circuit loop control.
