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.
Les modules de protection peuvent-ils être remplacés séparément ?
Yes. Its pluggable design allows individual protection modules to be inspected or replaced without removing the permanently wired base.
Que doit-on confirmer avant de commander ?
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.
