Siemens BQD20CP0D1 Remote Controlled Circuit Breaker

Siemens BQD20CP0D1 Remote Controlled Circuit Breaker is a remote-operable protection device built for Siemens' BQD/CQD frame family. The model combines a conventional circuit-breaker function with a dedicated remote-control mechanism (S1P0D) and is designated as an I-3 Remote Controlled Circuit Breaker Device, enabling remote opening and closing of the protected circuit and status signaling within a remote-control configuration. Designed for low-voltage distribution, it is used in panels and switchgear where centralized protection and safe, quick remote operation are required in industrial, commercial, or data-center environments. The BQD20CP0D1 part number uniquely identifies this device in Siemens’ lineup, with the S1P0D remote-control coding indicating the specific RC interface and control options supported by the unit. In practice, it integrates with Siemens auxiliary devices and signaling accessories to support remote control and fault signaling in panel installations, contributing to safer maintenance and faster fault response. This description reflects the device’s role as a remote-controlled protection element within Siemens’ protection and switchgear ecosystem.
