FAQ
Common questions about LY1-C40PV/3(S) 600V three-pole pluggable Type 2 DC surge protective device selection.
What is LY1-C40PV/3(S) 600V used for?
It is designed to limit lightning-induced and switching transient overvoltage in photovoltaic, telecom, energy-storage, and industrial DC systems operating up to 600V DC.
Is LY1-C40PV/3(S) 600V a Type 2 DC SPD?
Yes. The product is classified as Class II / Type 2 according to the current product specification and is intended for downstream DC surge protection.
What does the three-pole configuration protect?
The three-pole configuration is intended for multi-line DC systems requiring coordinated protection of positive, negative, and an additional monitored or grounded protection path. Installation must follow the supplied wiring diagram.
What discharge-current ratings does it provide?
It provides 20kA nominal discharge current In and 40kA maximum discharge current Imax, both based on an 8/20μs current waveform.
Can the protection modules be replaced separately?
Yes. Its pluggable design allows individual protection modules to be inspected or replaced without removing the permanently wired base.
What should be confirmed before ordering?
Confirm the maximum system voltage, three-pole wiring arrangement, grounding system, required voltage protection level, backup-fuse coordination, conductor size, installation location, and optional remote-contact requirement.
