Three-phase AC Protection Kit 20 kW Aurensol

Product Description

The Kit Protections AC Three-Phase 20 kW Aurensol brings together in a single weatherproof enclosure everything necessary to protect the AC stage of three-phase solar inverters up to 20 kW. Designed for professional installers and demanding projects, it combines surge protection, high-sensitivity residual current protection, and selective circuit breaker disconnection in an 18-module IP65 enclosure. Its organized design reduces assembly time, simplifies maintenance, and ensures technical compliance in 400/230 V networks.

Main Features

• IP65 weatherproof enclosure with 18 modules (1 row) for indoor or protected outdoor installation.
• Type 2 AC surge protector, 4 poles, 385 V, suitable for 400/230 V three-phase networks.
• Residual current circuit breaker 4P 40 A, 30 mA, Type A, high sensitivity for personal protection.
• Circuit breaker 4P 40 A, 400 V AC, curve C, fast disconnection in case of overloads and short circuits.
• Clear architecture and available space that facilitate expansions (measurement and control).

Advantages or Benefits

• Turnkey solution: avoids selection errors and reduces procurement time.
• Coordinated protection: SPD + residual current + circuit breaker for system efficiency and continuity.
• Robustness and durability: the IP65 enclosure protects against dust and water jets.
• Maintainability: organized and accessible layout that speeds up inspections and replacements.
• Versatility: suitable for 20 kW three-phase inverters in commercial and light industrial self-consumption.

Purpose or Applications

Ideal as an AC output protection panel in three-phase photovoltaic installations up to 20 kW: shops, workshops, small warehouses, offices, and tertiary buildings. It can be installed next to the inverter, as an intermediate panel before the main/general meter, or as a dedicated line panel, depending on the project design and required selectivity.
