surge protectors arrester (spd)

μ surge protection device functions: protection of heavy-loaded electrical circuit from overload used to protect not only particular consumers/circuits,but also the whole panel remarkable with high reliability of current characteristics control:automatic switching off at exit failture and recovery after eliminating the danger technical date: rated operating voltage Uc:the operating voltage ofsurge arrestor 275/440v;50Hz surge voltage Up:the voltage created in surge arrester terminals at rated discharge current running:according to the tables rated discharge current in the rated value of discharge current with a sinusoid 8/20us,which can be repeatedly led to the groud:according to the tables full discharge current imax the peak value of the discharge current with a sinusoid 8/20us,which the surge arrester can bear once:according to the tables constant operating current:up to 800 uA for 1p,2p,3p,up to 600 uA for 1p+N.3p+N indication for damaged suege arrester offtered in types:1p,1p+N,3p,3p+N
