Delixi CDLE6 Residual Current Circuit Breaker
Integrated 3P+N electronic residual current protection with digital display and RS485 communication.
Product Overview
The Delixi CDLE6 residual current operated circuit breaker provides electronic protection for three-phase four-wire TT distribution networks operating at AC 400 V and 50 Hz. Available in 100 A to 800 A frame sizes, it features an electronic release with adjustable overload, short-time short circuit, and instantaneous protection settings. The breaker incorporates Type AC residual current protection with 20 to 60 s automatic reclosing for delayed versions, a digital display for real-time monitoring, and external RS485 communication supporting DL/T 645 or Modbus protocols.
