FAQ
What type of surge protective device is GSP10-C40N?
GSP10-C40N is a Type 2 AC surge protective device for AC distribution panels and electrical equipment.
What is the difference between In and Imax?
In is the nominal discharge current, listed as 20kA. Imax is the maximum discharge current, listed as 40kA. Both ratings use the 8/20µs waveform.
Which Uc options are available?
The documented maximum continuous operating voltage options are 275V, 320V and 385V AC. Uc should not be read as a nominal system-voltage mapping.
Which connection topologies are documented?
The family documents 2P, 1+NPE, 4P and 3+NPE configurations. Specify the required topology and Uc when requesting a quotation.
Can this AC SPD be substituted for a DC PV SPD?
This page covers an AC surge protective device. A DC PV surge protective device is a separate product selection and should not be treated as interchangeable.
