FAQ
Common questions about LY1-C40PV/2(S) 600V two-pole pluggable Type 2 DC surge protective device selection.
What is LY1-C40PV/2(S) 600V used for?
It is designed to limit lightning-induced and switching transient overvoltage in photovoltaic, energy-storage, telecom, and industrial DC systems operating up to 600V DC.
Is LY1-C40PV/2(S) 600V a Type 2 DC SPD?
Yes. The current product classification identifies it as Class II / Type 2 for downstream DC surge protection.
What does the two-pole configuration protect?
The two-pole configuration provides separate surge-protection paths for the positive and negative DC conductors relative to protective earth.
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 cartridges be replaced separately?
Yes. The pluggable design allows each protection cartridge to be inspected or replaced without removing the permanently wired base.
What should be confirmed before ordering?
Confirm the maximum system voltage, positive and negative conductor arrangement, grounding system, required voltage protection level, backup-fuse coordination, conductor size, DIN-rail space, and remote-contact requirement.
