## Long description

Schneider Electric A9F04140 is a compact 40 A miniature circuit breaker designed for DIN-rail mounting in residential and commercial electrical panels. With IP20 protection and standardized dimensions, this device provides overcurrent and short-circuit interruption while occupying minimal panel space. Its 18 mm width, 78.5 mm depth and 91 mm height make it suitable for installations where a space-efficient protective device is required and where reliable switching performance is needed for branch circuits and distribution boards.
Advantages
The breaker combines a compact footprint with rated current capacity for common branch-circuit protection. IP20 degree of protection safeguards the internal mechanisms from accidental contact in standard indoor enclosures. Its DIN-rail format allows tool-free mounting and integration with modular distribution systems, while the device construction supports consistent tripping characteristics and short-circuit interruption required by typical electrical installations.
Suitable for
 Residential distribution boards and consumer units
 Small commercial and light industrial panels
 Protection of branch circuits for lighting and socket circuits
 Retrofit and new installations that require space-saving DIN-rail devices
Key specifications
 Rated current: 40 A
 Protection degree: IP20
 Mounting type: DIN-rail
 Width: 18 mm
 Depth: 78.5 mm
 Height: 91 mm
 Function: Overcurrent and short-circuit interruption for branch circuits
How to use
Install the device on a standard 35 mm DIN rail inside a suitable enclosure following local electrical regulations and safety standards. Ensure supply and load terminals are connected with conductors sized appropriately for a 40 A protected circuit and tightened to the manufacturer’s recommended torque. Verify correct polarity and mounting orientation, then test operation by switching under no-load and checking the trip behaviour under controlled conditions. Use appropriate protective measures (isolation, lockout) during installation and maintenance.
Usage recommendations
Use this miniature circuit breaker in indoor distribution panels where IP20 protection is acceptable. For locations exposed to moisture, dust, or where higher ingress protection is required, select an enclosure or device with an appropriate IP rating. Periodically inspect connections for tightness and signs of overheating, and replace the device if mechanical damage or repeated nuisance tripping occurs.
