     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產(chǎn)品內(nèi)部都有一個(gè)集成電路用于系統(tǒng)測試，并且在當(dāng)測試值滿足預(yù)設(shè)的安全值時(shí)使斷路器復(fù)位。在進(jìn)行電路測試期間，RESTART產(chǎn)生一個(gè)單向脈沖電流注入到下游電路中，這個(gè)測試電流的強(qiáng)度非常小，在任何情況下都可以保證人員的安全。

 

     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除了檢測線路對(duì)地的絕緣電阻外，也對(duì)系統(tǒng)是否存在短路情況進(jìn)行檢測。RESTARTRM測量兩個(gè)有效導(dǎo)體之間的電阻，如果這個(gè)電阻在1Ω之內(nèi)則不對(duì)斷路器進(jìn)行復(fù)位操作。

 

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

所有的設(shè)備都可以檢測漏電，即使在系統(tǒng)沒有接地的情況下。

 

    The table shows the different reset and block (or standby) values that the different versions of RESTART use as a reference, by comparing them to electrical system measured values.
