The Relpol RSP-EH12.5/100-750-10 is surge arresters for high-voltage applications, rated voltage 690 V AC. Plug-in design, class I+II (T1+T2). Peak current Iimp 4 kA 10/350, max. discharge current Imax 100 kA, rated discharge current 25 kA. For single-phase networks, single-pole VT technology Uc 750 VAC. Limiters with potential-free contact for remote fault signalling. Width 36 mm per pole.
The protection capability of RSP-EH12.5/100-750-10 is defined by the surge-current, operating-voltage, pole and class/type values stated above. Those exact ratings should be matched to the protected AC installation and its required lightning/surge protection level.
