Série NL1-T - Interrupteurs-sectionneurs DC - Type rail DIN étroit
Série NL1-T interrupteurs-sectionneurs c.c., slim 2P/4P up to 1200VDC.
Space-saving DIN-rail design, IP20, black handle.
IEC 60947-3 compliant; optimized for narrow PV panels and combiner boxes.
Vue d'ensemble
Le interrupteurs-sectionneurs c.c. La série NL1-T slim est un isolateur à faible encombrement pour
Boîtes de raccordement PV et
Panneaux DC.
With a thinner body compared to NL1, it is ideal for installations where panel space is limited.
Jusqu'à 1200VDC, available in 2P et 4P, it provides the same electrical
reliability in a slimmer enclosure.
