Use The switch is mainly used in rated isolating Ac1000v, rate frequency 50Hz srated operational voltage AC 380V(400v),and Rated operational urent 31 50AIt is mainly used in short-dir- cult current industrial ele dtrical sets,as the switch-disconne ctor or load-switch or emergency switch in power supply circut and motor circuit to preserve the circuits. The switch is obverse rotary operating type ,and most fts too be applied in drawer-switchbox.

The Hh15 series switch-disconnector-fuse and the HH15A (QA) &HHI5P (QP ) series switch-disconnector and double-throw transfer switch we produce are accord with JB/T8629-2006 standard

The Q switch accord with IEC 60947-3:1999

3 Normal operating conditions 3.1Surrounding air temperature A Maximum:No more than+ 40C B Minimum: No lessthan-5 C C Average temperature in 24 hours should not be m ore than+ 35C Note:when minimum temperature of surrounding air is un-der -10C or -25C .the customers should state to manufac turer on when plaoe an order. 3.2Altitude The altitude of installation place should not be higher than 2000 meters,when it is used in higher altitude place ,the cus- tomers should negotiate with m anufacturer.
