由此可知，电气火灾自动保护型断路器要达到对火灾作出正确的反应，最主要的是在安装时，要保证电气火灾自动保护型断路器上的热敏元件，即火灾感测探头，能直接感测到需要进行监测空间的温度变化。探头正前方不得有影响温度直接对其进行辐射传递的物体。如果电气火灾自动保护型断路器安装在照明箱内，而被监测区域的温度变化，不能被断路器上的火灾感温探头直接监测到，则达不到实现火灾自动保护的作用。
普通断路器功能。正常用电时，对受控线路进行人工闭合和分断电源操作。
火灾自动保护功能。当断路器所在位置（分体型为被探头监测位置）一旦发生火灾，环境温度异常升高，该断路器的感温探头在感测到所处环境温度达到或超过整定温度后，自动将受控线路电源切断，防止火灾扩大范围，并为灭火行动提供电气方面的安全保障，防止灭火人员发生电击后的二次伤害事故。
