Secure Circuit Breaker System

The RS-SE-501 Secure Circuit Breaker System enables control of in-home appliances using a secure wireless link. It is a fully self contained circuit breaker system with an integrated IEEE 802.11 bgn Wi-Fi sub-system, contactors, AC-DC transformer, microcontroller, power management unit and built-in antenna along with an option to connect an external antenna. This system retains the existing electro-mechanical circuit breaker functionality for over-current protection and provides a manual overrid of the Wi-Fi based control. In addition to the WLAN functionality with WPA2 security, this system also implements IPSec and a network stack that terminates TCP/IP and UDP connections with IPv6 capability. This system can be configured through UART or through wireless.
