Série NL1-T - Interrupteurs-sectionneurs DC - Type rail DIN étroit
NL1-T series 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
DC panels.
With a thinner body compared to NL1, it is ideal for installations where panel space is limited.
Rated up to 1200VDC, available in 2P and 4P, it provides the same electrical
reliability in a slimmer enclosure.
