Description
The IMO SI32-PEL64R-4 is a professional-grade, 4-pole photovoltaic DC isolator engineered to provide safe, reliable manual disconnection between solar panel arrays and inverters. Designed specifically as a true DC switch—rather than a de-rated AC switch—it ensures maximum circuit protection and compliance with international solar installation standards. Housed in a rugged, weather-resistant enclosure, this unit supports 2 independent PV strings at 32A and is built to handle demanding residential and commercial solar environments.
Features
- True DC Switch Disconnector: Built explicitly for DC applications to safely interrupt high-voltage solar loads without relying on modified AC switch architecture.
- Dual-String & 4-Pole Configuration: Configured with 4 poles to seamlessly isolate 2 separate photovoltaic strings (positive and negative lines per string).
- High-Speed Switching Mechanism: Features an operator-independent, rapid-trigger snap action (~3 ms switching time) that drastically reduces arcing.
- Advanced Arc Suppression: Equipped with self-cleaning knife-edge contacts and dedicated arc cooling chambers to extend switch lifespan and prevent electrical degradation.
- Weatherproof Outdoor Enclosure: Housed in an IP67 / NEMA 4X rated, UV-resistant, and impact-tough polycarbonate enclosure designed to endure harsh outdoor weather conditions.
- Lockable OFF Safety Function: Includes a padlockable rotary handle ("Safe-Lock") to prevent accidental operation and ensure safety during system maintenance.
- Installer-Friendly Design: Compact footprint featuring spacious box terminals (supporting 4–16 mm² / 12–10 AWG cables) and convenient knockouts for straightforward wiring.
- Certified Safety Standards: cUL and UL 508i listed, meeting rigorous compliance requirements for modern solar installations.
