All the RESTART range is equipped with an integrated electronic circuit which can test system condition and allows the resetting of circuit breaker if the measured values are compatible with presetting safety values. During the electric circuit test, RESTART injects into the downstream electrical system a pulsating unidirectional current in order to check its condition. The test current intensity is extremely low, so the safety of people is guaranteed in all circumstances.

     所有的RESTART产品内部都有一个集成电路用于系统测试，并且在当测试值满足预设的安全值时使断路器复位。在进行电路测试期间，RESTART产生一个单向脉冲电流注入到下游电路中，这个测试电流的强度非常小，在任何情况下都可以保证人员的安全。

 

     RESTARTRM, besides checks earth insulation resistance, also tests the electrical system for short circuit. The device measures the impedance between two active conductors and if the value is equal to or less than 1 Ω, the reset will not carried out.

RESTARTRM除了检测线路对地的绝缘电阻外，也对系统是否存在短路情况进行检测。RESTARTRM测量两个有效导体之间的电阻，如果这个电阻在1Ω之内则不对断路器进行复位操作。

 

     All devices can detect faults also for electrical systems without earthing.

所有的设备都可以检测漏电，即使在系统没有接地的情况下。
