FAQ
Common questions about LY1-C40/3(S)+1 pluggable 3P+N Type 2 AC surge protective device selection.
What is LY1-C40/3(S)+1 used for?
It is used for Type 2 surge protection in three-phase plus neutral AC distribution systems, with coordinated protection between L-N and N-PE.
O que significa 3P+N?
3P+N means the SPD is designed for three-phase plus neutral systems, with L-N protection across the phases and coordinated N-PE protection.
Por que este modelo utiliza proteção MOV e GDT?
MOV elements provide fast voltage clamping on the L-N paths, while the GDT supports coordinated discharge on the N-PE path with low leakage during normal operation.
Quais são as classificações de corrente de descarga que ele fornece?
O SPD proporciona uma corrente de descarga nominal de 20kA In e uma corrente de descarga máxima de 40kA Imax para os caminhos de proteção L-N e N-PE.
Quais opções de voltagem estão disponíveis?
L-N maximum continuous operating voltage options include 75V, 150V, 275V, 320V, 385V, and 440V AC. The N-PE continuous operating voltage is 255V.
O que deve ser confirmado antes de fazer o pedido?
Confirm the system voltage, 3P+N arrangement, L-N and N-PE protection mode, backup fuse, wiring cross-section, DIN-rail space, and remote contact requirement.
