SCHNEIDER A9F44110 Miniature Circuit Breaker

Description

SCHNEIDER A9F44110 Miniature Circuit Breaker

Product Overview

The Schneider Electric A9F44110 is a 1-pole Miniature Circuit Breaker (MCB) from the renowned Acti9 iC60N series. Designed for low-voltage electrical distribution systems, it provides reliable protection against short-circuit currents and overload conditions in commercial, industrial, and residential environments.

Featuring a C-curve tripping characteristic and a 10 A rated current, this breaker is engineered to handle moderate inductive inrush currents commonly found in standard lighting circuits, small appliances, and general control circuits.

Technical Specifications

Key Advantages

• VisiSafe™ Technology: Features a green indicator bar that guarantees physical open contact position, ensuring safe downstream maintenance work.
• VisiTrip™ Fault Indicator: Front-panel visual trip indicator flags short-circuit or overload faults instantly, minimizing downtime and diagnostic effort.
• High Reliability & Longevity: Fast-closing mechanism limits wear and tear on contacts during manual or automatic operation, extending service lifespan.
• Double Insulation Class II: Front panel design ensures maximum operator protection against shock hazards during device manipulation.
• Seamless Compatibility: Fully compatible with Acti9 system accessories (comb busbars, auxiliary contacts, shunt trips, and undervoltage releases).

Important Usage & Installation Precautions

• Current Rating Matching: Ensure the circuit’s maximum continuous load does not exceed 10 A. Overloading the breaker will lead to nuisance tripping.
• Inrush Current Considerations: The C-curve profile is suited for general distribution loads. For applications with very high inrush currents (e.g., large motor starting or high-capacity transformers), a D-curve breaker may be required instead.
• Tightening Torque: Torque terminal screws to the recommended spec (typically 2 N·m) using an insulated torque screwdriver to prevent high-resistance hot spots or loose connections.
• Environmental Limits: Operating temperature range is -35 °C to +70 °C. Derating factors must be applied if installed in high ambient temperature environments or tightly packed enclosures.
• De-Energize Before Service: Always isolate upstream power before connecting, disconnecting, or replacing the circuit breaker.

Applications

• Commercial & Residential Lighting: Circuit protection for LED, fluorescent, or incandescent lighting control circuits up to 10 A.
• General Socket Outlets & Small Appliances: Short-circuit and thermal overload protection for standard office, shop, and home branch circuits.
• Industrial Control Cabinets: Protection for PLC power supplies, auxiliary relay circuits, control transformers, and sensor lines.
• HVAC Control Loops: Circuit protection for low-power actuators, thermostat control panels, and fan coils.
