PGK 1000V DC Isolator BYH-32A

The DCI1000V is a compact, high-performance 1000V DC isolator designed for rooftop and ground-mount solar PV installations. Rated to 32A and IP66, it provides safe disconnection of PV strings under load, protecting installers, service technicians, and equipment during installation, maintenance, or emergency isolation.

With fast arc suppression, non-polarised contacts and a robust UV-stable enclosure, the DCI1000V is suited to New Zealand’s harsh outdoor conditions and complies with current DC isolation requirements for PV systems. It can be mounted adjacent to the array or at the inverter to provide reliable, long-term isolation in residential, commercial, and light industrial solar applications.
