Solar PV DC 1000 Volt Isolating 3 Phase Main Switch for Power System

Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • High-Voltage Isolation: Designed to safely disconnect solar panels from DC power systems (up to 1000V/32A), ensuring maintenance safety and system protection.
  • 4-Pole Operation: Enables reliable handling of multi-phase electrical paths, enhancing redundancy and safety in photovoltaic installations.

Key features

  • 1. UV-Resistant ABS Material Technology

    • With UV-resistant ABS construction, you can ensure long-term durability in outdoor solar installations, resisting degradation from prolonged sunlight exposure. This outperforms standard plastic materials prone to brittleness over time.*

  • 2. Safety-Enhanced Interactive Design

    • With a lockable handle and red visual indicator, you can achieve secure disconnection and instant status confirmation, reducing risks of accidental activation compared to non-lockable switches.*

  • 3. High-Performance 32A/1000V DC Rating

    • With a 32A rated current and 1000V DC capability, you can handle robust solar system demands, exceeding the capacity of lower-voltage switches for safer, reliable operation.*

  • 4. 4-Pole Design for Versatile Scenario Solutions

    • With a 4-pole configuration, you can ensure redundancy and stability in 3-phase PV systems, ideal for both residential and commercial setups, unlike single-pole switches limited to basic applications.*

  • 5. Certified Compliance for Peace of Mind

    • With CE certification, you can meet European safety and environmental standards, ensuring trustworthiness compared to uncertified alternatives.*

Supplier's note

  1. Technical Breakthroughs:

    • UV-Resistant ABS: Extends lifespan in direct sunlight compared to traditional plastic materials.
    • 4-Pole Design: Reduces grounding faults by 40% versus 3-pole switches in 3-phase systems.
    • CE + IEC 61000 Compliance: Ensures compatibility with 90% of global solar inverters.

  2. Optimal Version Selection:

    • Base Model: Ideal for residential systems (≤32A) requiring basic isolation and cost efficiency.
    • Advanced Model: Suitable for commercial rooftops (≤40A) needing IP65 protection against dust/water.
    • Pro Model: Best for industrial-scale installations (≤50A) requiring UL certification and IP67 submersion resistance.

The Pro version’s IP67 rating enables safe use in coastal areas with high humidity, paired with its 50A capacity to support large solar farms. When combined with UL certification, this creates a globally deployable solution for utility-scale projects.
