Technical data

The Cooper three-module photovoltaic surge protective device(SPD) (with three -step DC switching device) features visual indication and optional remote contact signaling (floating changeover contact) for use in PV systems. These complete surge protective devices are suitable for all PV systems in accordance with IEC 60364-7-712. Includes a five year limited warranty. These prewired solutions consist of a base and locking modules that feature a combined and short-circuiting (shunting) device with safe electrical isolation to prevent fire damage due to DC arcs. An integrated DC fuse allows safe module replacement without arc formation. In case of insulation faults in the generator circuit, a reliable and tested fault-resistant Y circuit prevents damage to the surge protective devices. The green and red visual indicator flags show the module protective status ( green =good, red =replace). Apart from this visual indication, the remote signaling option features a three terminal floating changeover contact that can be used as a make or break contact depending on the particular monitoring system design employed.

Questions about this model

How do I get a price for the Solar DC Surge

Email [email protected] or message us on WhatsApp with the model, the ratio, the accuracy class, the burden in VA and the quantity.

What is the burden and why do you ask for it

The burden is the total termination impedance seen by the transformer: the measuring instrument, the connecting leads and the winding itself. Accuracy class cannot be guaranteed without it, and long lead runs add resistance that has to be counted.

Can this model be customised

Ratios, secondary current and mounting can often be adapted within the same frame. Send us the requirement and we will confirm what the frame allows.
