小型断路器是用于低压电气设备，保护导体、开关及电器，防止过载和断路的。它们能够满足与电气设备相关的各种条件，代表了各个行业中技术性能及经济性最佳的解决方案，广泛应用于工业、政府设施高技术公共设施及家电等行业。它们是按照现行国际标准（IEC60898）制造的，分为7个产品系列，覆盖范围为电流0.3A~125A，电压230/400V，同时可按与之相关的附件及辅助开关进行分类。它们用搭锁安装在符合EN50022及DIN46277标准的 35mm的对称护拦上
。
西门子5S系列小型断路器主要用于配电线路、负载、照明等电器设备的过载及短路保护等。
主要功能特点：
1. 采用漏斗式组合型接线端子使接线简单可靠；可方便地连接汇流母线排，并可以通过附加接线端子使进线或出线的端子容量达35mm2
2. 触头系统采用银合金材料(银锡或银石墨)，真正做到了无熔焊。
3. 采用快速灭弧系统，由动触头锁定片、引弧导板、磁吹金属片和金属灭弧栅片等部件构成。灭弧室中有多达13片的金属栅片，可迅速将电弧熄灭，平均短路分断时间仅为3.7 ms。
4. 能量限制等级比 3 还要高(能量值仅为等级 3 的50%)。
5. 选择性配合保护好。可与上级的熔断器，塑壳式断路器等产品形成良好的选择性保护。
6. 断路器均能满足IEC898的标准，分断能力最高可达10KA（如用于工业IEC947－2标准最高达25KA。
7. 断路器脱扣特性有A、B、C、D四种，额定电流范围从0.3－125A。可以适用于各种不同的使用范围
8. 断路器的外壳采用热固性材料制成，具有很高的耐热性和抗冲击强度，绝缘强度高。
9. 断路器外形为标准模数化结构，体积小重量轻；安装部件采用金属片和弹簧，可以安全牢固地卡装在35mm的标准导轨上。
10. 断路器可与多种附件相连接，如用于手柄锁定的锁定装置，它可以防止无关人员去操作断路器，另外还有辅助开关、故障报警开关、分励脱扣、欠压脱扣等附件可供选择。

5SM系列剩余电流保护断路器在检测到对地的故障电流(漏电电流)后与漏电脱扣电流值进行比较当故障电流值大于脱扣电流值时开关会将回路分断.有AC型A型B型三种.
AC型:用于交流故障的剩余电流保护断路器;
A型:用于交流和直流脉动分量故障电流剩余电流保护断路器;
B型:用于交流和直流脉动分量故障电流以及直流平滑故障电流的剩余电流保护断路器;
5SU系列带过电流动作的剩余电流保护断路器是用于电器设备的过电流保护以及间接接触带电体的保护。特别用于漏电电流小于或等于30MA时，作为直接接触带电体的一种附加保护。有A型和AC型两种。
