PZH R3 HSAD16/*VDC is a surge arrester designed for DC power supply systems. PZH R3 HSAD16/*VDC contains an improved thermal fuse which ensures timely disconnection of the device from the power grid during overheating and thus prevents damage to the PZH R3 HSAD16/*VDC. Activation of the thermal fuse is signalled by an integral indicator light with the option to utilize its switching contact for remote fault signalling (S). The PZH R3 HSAD16/*VDC is a type T3 two-port surge arrester and has been tested according to standards EN 61643-11 (IEC 61643-11:2011). According to standard EN 62305 (IEC 62305:2010), it is installed in the boundary between zones LPZ 2 - LPZ 3, where it limits induced overvoltage and residual overvoltage in power lines. PZH R3 HSAD16/*VDC are designed to be mounted on a 35 mm DIN rail using a metal clip. Manufacturer’s recommendation: Install the PZH R3 HSAD16/*VDC as close to the device to be protected as possible (no further than 5 m). There must be HERMI’s lightning and surge arrester T1 and T2 installed before the PZH HSAD16/*VDC.
