AC Protection Box Single-phase GAVE ACM40SDA 9.2kW 40A 30mA

Product description

The GAVE ACM40SDA 9.2kW 40A 30mA Single-Phase AC Protection Box is a turnkey modular panel for protecting and connecting an AC branch of up to 9.2 kW in self-consumption or backup installations. It combines in a single Class II polycarbonate enclosure (double insulation) and IK7 the disconnection, miniature circuit breaker protection, high-sensitivity residual current protection, and transient surge protection (Type II SPD), speeding up assembly, organizing the installation, and facilitating compliance with best practices.

Main features

• Single-phase 230 V · 50 Hz, 1 dedicated AC circuit with continuous capacity up to 40 A (≈ 9.2 kVA/kW).
• 2P 40 A miniature circuit breaker (MCB), curve C, breaking capacity 6 kA (EN 60898-1).
• Type A residual current device (RCD) 30 mA, 2 poles, immune to unwanted tripping.
• Type II SPD surge protection (In 20 kA, Imax 40 kA, Up 1.5 kV) with associated fuse.
• Compact polycarbonate enclosure with double insulation Class II and IK7 resistance rating.
• Internal wiring and DIN rail arrangement for quick and maintainable installation.

Advantages or benefits

• Faster and cleaner installation by centralizing protections, disconnection, and connection of the PV/AC branch.
• Increased safety: 30 mA RCD for personal protection and Type II SPD to mitigate grid transients.
• Facilitates technical compliance and selectivity with upstream protections.
• Simple maintenance: front access to devices, clear labeling, and streamlined wiring.

Purpose or applications

Ideal as an interconnection and safety point between single-phase inverters of ~6–9 kW or strings of microinverters (aggregate ≤ 40 A) and the main distribution board in residential or small commercial settings. Also valid in AC-coupled battery schemes when the line current does not exceed 40 A.

Technical specifications

Compatibilities

Compatible with single-phase inverters of ~6–9 kW and with microinverter strings (Enphase, Hoymiles, etc.) as long as the total does not exceed 40 A at 230 V. Can be coordinated with main circuit breaker, main residual current device, and main SPD according to the project, and can be integrated with monitoring via external current transformers.

GAVE ACM40SDA 9.2kW 40A 30mA Single-phase AC Protection Box is the professional option to centralize safety, organization, and reliability in the AC branch of your installation, optimizing assembly times and protecting equipment and people.
