This is a wireless auxiliary contact that remotely displays the status of the circuit breaker. It is used with ComPacT NSXm and PowerPacT B. This wireless auxiliary contact provides ON/OFF information that indicates the switch position of the circuit breaker. It delivers trip indication information, which shows that the circuit breaker has tripped due to an electrical fault, the activation of a voltage release, or a trip button. It provides fault trip indication information, indicating that the circuit breaker has tripped due to an electrical fault (overload, short circuit, earth fault, residual current). This wireless auxiliary contact operates with the Zigbee wireless communication protocol (IEEE 802.15.4) in the frequency range of 2405-2480 MHz. It features a plug-and-play technology for clear connection status. This wireless auxiliary contact is mounted in the same location as the wired version. An integrated LED light indicates a trip. The communication architecture is fully EcoStruxure Power validated, with every application.
