Ang DNRH8 Combined Switch mao ang usa ka kompletong solusyon sa pag-switch ug isolation sa DC load, na rated hangtod sa 1500 VDC ug 630 A. Gitukod aron mosangpot sa DC-PV1, DC-PV2, ug DC-21B utilization categories, giintegrate nito ang main ug pre-charge relays sa usa ka compact, IP67-rated housing. Ideal para sa photovoltaic (PV) systems, battery energy storage systems (BESS), ug industriyal nga DC applications, ang DNRH8 nagstreamline sa installation, namalit sa wiring errors, ug naghatag og mabilis ug reliable nga switching pinaagi sa undervoltage protection.
Voltage & Current: DC 1500 V, operational current 200 A–630 A.
Switching Capacity: Making/withstand capacity 15 kA (0.1 s) / 10 kA (1 s); conditional short-circuit current 100 kA.
Arc Performance: Arc distance minimized; arcing time < 3 ms.
Protection Rating: IP67 (external); IP20 (internal).
Control Modes: Manual or 24 V remote control with auto/manual selection.
Undervoltage Module: Active/passive trip options (response < 0.5 s, 2 min power-loss backup).
Optional Relay Module: JDQMK series integrates main/pre-charge relays and resistors.
