Siemens SB Encased Systems Breakers bridge the performance gap between Molded Case Circuit Breakers (MCCB) and Low Voltage Power Circuit Breakers (LVPCB). Modern computer-aided design and manufacturing tools were used to effectively blend the technologies of the MCCB and LVPCB. This combination has resulted in a family of encased systems circuit breakers that exhibit the most desirable characteristics of each of the parent technologies. Included in these characteristics are high interrupting capacities, high withstand capabilities (magnetic stress), high short-time capabilities (overcurrent heating), and high mechanical and electrical endurances, without maintenance. Applications for SB breakers include main, tie, feeder, and emergency source breakers in industrial plants, large commercial complexes, and medical and health care facilities. The circuit breakers are constructed for either fixed or drawout installation. They can be physically grouped in central distribution switchboards, or used separately in standalone applications.
The SB breaker is equipped with a two-step stored energy mechanism for closing and opening the breaker contacts. After a closing operation sufficient energy is retained in the two-step stored energy mechanism to perform the tripping function. The mechanism may be charged manually with the integrated low-force charging handle or electrically with the optional electric motor operator. Pushbuttons, switches and color-coded indicators allow for easy close and open operations.
西门子SB封装系统断路器填补了塑壳断路器(MCCB)和低压电力断路器(LVPCB)之间的性能差距。现代计算机辅助设计和制造工具被用来有效地融合MCCB和LVPCB的技术。特点包括高中断能力,高耐受能力(磁应力),高短时能力(超电流加热),以及高机械和电耐久性,不需要维护。在工业厂房、大型商业综合体、医疗保健设施中断路器的结构是固定的。它们可以在中央分布配电板上进行物理分组,也可以单独在独立的应用程序中使用。
断路器配备有两步储能机构,用于关闭和打开断路器触点。在关闭操作后,在两步存储的能量机构中保留足够的能量来执行跳闸功能。该机构可以用集成的低压力充电手柄或电动马达操作。按钮,开关和颜色编码指示器允许容易关闭和打开操作。
