The Siemens NXD63S120A is a non-automatic molded case circuit breaker engineered to manage significant electrical loads efficiently. This device operates at a rated voltage of 600 VAC and supports a substantial current rating of 1200 A. It utilizes a bolt-on connection type, facilitating secure and reliable mounting within electrical systems.
Featuring three poles, the NXD63S120A is specifically designed for three-phase power applications. This unit is classified under the ND frame type, which contributes to its robust construction. It is important to note that this breaker does not provide overcurrent protection, as emphasized by its designation as a non-automatic switch, making it crucial to consider its placement within any electrical design where such protection is required.
In terms of performance, the unit carries an interrupting rating of 50 KAIC at 480 VAC, sufficient to handle fault conditions and ensure safety in high-demand situations. The absence of lugs means that users must account for this during installation, opting for appropriate terminal connections that suit the application at hand. Overall, the NXD63S120A is tailored to deliver reliable service in industrial environments where capacity and dependability are essential.
