PN2-VA3 Self-Resetting Over/Under Voltage Protector 40A–80A

Electrical contractors working on commercial distribution boards, office fit-outs, and retail unit power installations need protection devices that are easy to inspect and commission on-site. The Soltree PN2-VA3 is built with professional installers in mind — its dual digital display uses white voltage digits and green current digits, a combination that delivers noticeably sharper contrast under the bright fluorescent lighting found in commercial electrical rooms, switchgear enclosures, and panel inspection environments.

Where the PN2-VA2 is specified for residential and home use, the PN2-VA3 is the preferred choice for commercial electrical contractors supplying office buildings and retail chains, panel builders working to professional installation standards, and export projects where CE and RoHS certification is a procurement requirement.

The protection platform is fully configurable: over-voltage threshold (130–300V AC), under-voltage threshold (80–210V AC), and over-current trip are all set via the front panel, with 0.5-second automatic disconnect on fault and automatic power restoration once the supply stabilizes. Reset delay is adjustable from 0 to 999 seconds (default 60s) to prevent nuisance tripping in commercial circuits. A password lock prevents unauthorized changes in multi-tenant commercial premises. Available in 40A, 63A, and 80A variants; AC 110V customizable for international export markets. 35mm DIN rail mounting. CE and RoHS certified.
