Suitable for overcurrent protection in residential and light commercial electrical circuits.

## Long description

Schneider Electric A9F03120 is a miniature circuit breaker designed for overcurrent protection in residential and light commercial electrical installations. The device is rated for 20 A nominal current and operates at system voltages up to 133 V. With a rated breaking capacity of 10 kA and an IP20 degree of protection, this compact circuit breaker is intended for DIN-rail mounting and integrates into standard distribution boards while occupying only 18 mm of module width.
Advantages
The A9F03120 combines a compact 18 mm width with a high breaking capacity, allowing reliable interruption of short-circuit currents up to 10,000 A. Its DIN-rail mounting and standardized dimensions simplify installation and make it suitable for confined electrical panels. The IP20 protection rating provides basic protection against accidental contact with live parts, and the robust mechanical design supports consistent performance under normal operating conditions.
Suitable for
Overcurrent protection of lighting and socket circuits in homes
Protection of small commercial and office electrical circuits
Use in modular DIN-rail distribution boards and consumer units
Key specifications
Rated current: 20 A
Rated operational voltage: up to 133 V
Breaking capacity: 10 kA
Degree of protection: IP20
Mounting type: DIN-rail (standard rail-mounted enclosure)
Width: 18 mm

How to use
Mount the circuit breaker onto a standard DIN rail inside the distribution board, ensuring the device is positioned and fastened according to local electrical regulations. Connect the line and load conductors to the appropriate terminals, tighten terminals to the manufacturer’s specified torque, and verify correct polarity and continuity before energizing the circuit. Use the breaker as the primary overcurrent protective device for the circuit, and operate the toggle to switch the circuit on or off during maintenance when power is isolated upstream.
Recommendations for use
Install and commission the device following national electrical codes and Schneider Electric installation instructions. Confirm compatibility with circuit characteristics and upstream protection devices, periodically inspect terminals for tightness, and replace the breaker if it shows signs of mechanical damage or repeated tripping that indicates underlying circuit faults.
