Schneider Electric NSNBC01 Molded Case Circuit Breaker

NSNBC01 is a Schneider Electric interlock kit (EIK1) designed to accompany Square D NS-series molded‑case circuit breakers, providing a dedicated mechanical interlock accessory for NS panel assemblies and ensuring that the interlock mechanism can be integrated into existing NS distribution configurations. As part of the EIK1 interlock family, NSNBC01 enables a controlled interface between the breaker handle and adjacent interlocking components, supporting safe maintenance by preventing inadvertent exposure to live parts when the system is energized. Ideal for industrial and commercial installations that employ NS-series molded‑case breakers, NSNBC01 is typically specified in safety‑critical switchgear configurations to help meet interlock and clearance requirements for NS equipment. When selecting this accessory, verify compatibility with your exact NS breaker model and enclosure, and ensure installation follows Schneider Electric's guidelines to maintain overall system safety and compliance. The NSNBC01 interlock kit is commonly sold under the EIK1 designation, reflecting Schneider Electric's standardized naming for interlock accessories across the Square D NS line.
