FAQ
Common questions about LY1-C40M/3(S)+1 compact 3P+N pluggable Type 1+2 AC surge protective device selection.
What is LY1-C40M/3(S)+1 used for?
It is used for compact Type 1+2 surge protection in three-phase plus neutral AC systems, with coordinated protection between L-N and N-PE.
What does 3P+N mean?
3P+N means the SPD is designed for three phase conductors plus neutral, with L-N protection paths and a coordinated N-PE protection path.
Quali valutazioni di sovratensione fornisce questo SPD?
It provides 20kA nominal discharge current and 40kA maximum discharge current. Its impulse discharge current is 7kA on the L-N paths and 25kA on the N-PE path.
Quali opzioni di tensione sono disponibili?
Le opzioni di tensione continua massima operativa L-N disponibili sono 75V, 150V, 275V e 320V CA. La tensione continua operativa N-PE è di 255V.
Qual è il vantaggio del design compatto e modulari?
The compact structure reduces DIN-rail space, while the pluggable cartridges simplify inspection and replacement without removing the complete wired base.
Cosa dovrebbe essere confermato prima di ordinare?
Confirm the L-N system voltage, 3P+N circuit arrangement, N-PE protection requirement, 63A maximum backup fuse, conductor size, DIN-rail space, and remote-contact requirement.
