Three-phase AC Protection Box GAVE ACT63SDA/300 44kW 63A 300mA

Product Description

The GAVE ACT63SDA/300 44kW 63A 300mA Three-Phase AC Protection Box is a turnkey 3F+N panel designed to protect and connect, with maximum reliability, high-flow AC branches in three-phase installations. It integrates, in a single polycarbonate enclosure with double insulation (Class II) and IK08, a four-pole 63 A circuit breaker, a Type A selective 300 mA residual current device—ideal for fire protection and to ensure selectivity with downstream RCDs—and a Type II surge protection device (SPD). With this configuration, the panel reduces installation time, organizes wiring, and ensures technical compliance in self-consumption, backup, or light/medium C&I systems up to ~44 kW.

Main Features

• Electrical capacity: up to 63 A per phase (≈ 43.6–44 kVA/kW at 3×400/230 V, 50 Hz).
• 4P 63 A circuit breaker (MCB), curve C, 6 kA breaking capacity according to EN 60898-1.
• 4P Type A 300 mA selective RCD, immune to unwanted tripping (EN 61008-1).
• Type II SPD (In 20 kA, Imax 40 kA, Up 1.5 kV) with associated fuse (EN 61643-11).
• Class II polycarbonate enclosure, high impact resistance IK08, suitable for protected outdoor use.
• Streamlined internal wiring and DIN rail for quick, clean, and maintainable installation.

Advantages or Benefits

• Selectivity and service continuity: the 300 mA (S) RCD reduces nuisance tripping, protects against fire risk, and maintains selectivity with 30 mA RCDs in subpanels.
• Integrated safety: circuit breaker, RCD, and SPD in the same panel protect people and equipment against overloads, indirect contact, and network transients.
• Agile and orderly installation: fewer field connections, accessible terminals, and clear labeling shorten commissioning and facilitate maintenance.
• Technical compliance: switchgear and construction in accordance with IEC/EN standards, facilitating audits and legal certification of installations.
• Robustness and durability: quality materials, double insulation Class II, and IK08 for demanding environments (indoor or protected outdoor).

Purpose or Applications

Designed to act as an interconnection and safety point between AC generation/backup and the main panel in high-power three-phase installations. Its use is ideal in advanced residential self-consumption, tertiary, and light/medium C&I, with string inverters of 30–40+ kW or branches of three-phase microinverters, as well as in systems with AC-coupled batteries when the line current does not exceed 63 A/phase. It is also suitable for schemes with export limitation and energy monitoring via CT or external meters.

Technical Specifications

Compatibilities

Compatible with three-phase inverters of 30–40+ kW and with 3F microinverter branches, provided the aggregate does not exceed 63 A/phase. It can be integrated with monitoring systems (CT/meters), selectivity with IGA and 30 mA RCDs in subpanels, and coordination with main SPD according to project and local regulations.

GAVE ACT63SDA/300 44kW 63A 300mA Three-Phase AC Protection Box is a professional solution for demanding projects: it provides comprehensive safety, differential selectivity, panel organization, and reliability at the AC interface, optimizing installation times and protecting equipment and people from day one.
