BR1D2AC Equivalent & Substitute Parts

Part Overview

The BR1D2AC is a single-pole circuit breaker manufactured by Weidmüller, designed for AC/DC applications with a 2A current rating. This component is classified as obsolete, indicating that direct procurement may be limited. The BR1D2AC operates as a branch circuit breaker with D-curve characteristics, suitable for thermal-magnetic protection in industrial control and distribution applications. Due to its obsolete status, identifying functionally equivalent active alternatives is essential for system maintenance, replacement, and new design implementations.
