SG2DGK50M3 - Lovato - Surge protection device

<h3>Surge protective device for electrical panels</h3><p>This surge protection component limits transient overvoltages in electrical panels and protects downstream equipment from surge events. It is used in machine control, distribution and photovoltaic circuits when specified, where surge current must be diverted through a coordinated protective path.</p><h4>Surge data and circuit coordination</h4><p>component type surge protective device; SPD type type 2; short-circuit current 11 kA; voltage 1500 VDC; remote contact without remote contact; application photovoltaic. Selection must follow SPD type, discharge current values, pole arrangement, voltage level and the presence of any remote signalling contact. Plug-in cartridges must match the base series and the protected circuit so that maintenance can restore the same protective function.</p><h4>Inspection and replacement</h4><p>During service, check the indicator or remote signal, compare cartridge data with the installed base and verify the connection to the protective conductor path. After replacement, restore markings and repeat the visual inspection before returning the panel to operation.</p><p>The panel record should identify the protected line, earthing path and any remote signal used by the monitoring system. When a cartridge is replaced, keep the same surge type, current rating and voltage level, then check the indicator state before closing the panel.</p><p>Correct coordination also makes routine inspection easier: the operator can read the local indication, compare it with the remote alarm when present and immediately understand whether the protective path is still ready to divert the next transient surge.</p><p>For mixed distribution and automation panels, consistent labelling of the protected feeder helps maintenance teams distinguish power supply, control and photovoltaic lines during inspection.</p> <h3>Surge protective device for electrical panels</h3><p>This surge protection component limits transient overvoltages in electrical panels and protects downstream equipment from surge events.
