Key Features

The A9F77220 offers reliable two-pole circuit protection with simultaneous disconnection of phase and neutral, improving safety and ease of maintenance. Its C curve tripping makes it ideal for protecting circuits that serve loads with modest start-up surges such as lighting, receptacles, and small motors.

It is part of Schneider’s Acti9 series, known for advanced safety features, modularity, and ease of installation. Features like VisiTrip (fault indicator) and VisiSafe (safety disconnection indicator) are included on compatible models in this series, helping to enhance safety and speed up fault detection and service operations.

The breaker also features a long electrical and mechanical lifespan, with up to 10,000 electrical operations and 20,000 mechanical operations, making it suitable for demanding environments and frequent switching.

Applications

• Residential Installations: Circuit protection for household power outlets, lighting, and HVAC systems.

• Commercial Buildings: Used in distribution panels for general-purpose power circuits in offices, retail spaces, and schools.

• Industrial Control Panels: Protects control circuits, automation devices, and low-load machinery.

• Public Infrastructure: Applied in lighting control and protection systems in public buildings and transport hubs.

• Backup Power Systems: Can be integrated into UPS and generator input/output panels for secure switching and protection.
