Thermal isolating device with optical indication permanent check of arrester serviceability.5. An extremely short response time, a low protection level and a high current diversion capacity combined with long life.6. No follow-up current can be registered after the surge has decayed.7. If the surge arrester is damaged by overloading, the integral isolating device breaks the connection to the mains. This is signaled by a red fault indicator.8. The surge arrestor can easily be installed in any distribution box or switchgear cabinet by snap-fitting to any commercial 35 mm top-hat rail.9.
