PREGUNTAS FRECUENTES
Common questions about LY1-C40/2(S) two-pole pluggable Type 2 AC surge protective device selection and installation.
What is LY1-C40/2(S) used for?
LY1-C40/2(S) is used to limit transient overvoltage in low-voltage AC distribution systems through two protection paths. It is suitable for distribution boards, control cabinets, commercial power systems, and equipment panels.
Is LY1-C40/2(S) a single-pole or two-pole SPD?
LY1-C40/2(S) is a two-pole SPD. The existing page title describing it as single-pole should be changed to two-pole.
Is this product a Type 2 SPD?
Yes. LY1-C40/2(S) is classified as a Class II / Type 2 AC surge protective device. The incorrect Type 1CA wording should not be used.
¿Qué clasificaciones de corriente de descarga proporciona?
El SPD proporciona una corriente de descarga nominal In de 20kA y una corriente de descarga máxima Imax de 40kA. La tabla técnica también incluye un parámetro de corriente de impulso de 7kA.
¿Qué opciones de voltaje están disponibles?
Maximum continuous operating voltage options include 75V, 150V, 275V, 320V, 385V, and 440V AC. Select the appropriate version according to the nominal system voltage.
¿Qué se debe confirmar antes de ordenar?
Confirm the nominal voltage, Uc and Up requirements, two-pole protection arrangement, 125A maximum backup-fuse coordination, conductor size, DIN-rail space, and optional remote-contact requirement.
