Product information

Description

Schneider Electric A9F04340 is a miniature circuit breaker designed for overload and short-circuit protection in panel and distribution board applications. Rated for 40 A and 133 V, this compact device provides a 10 kA breaking capacity and IP20 enclosure protection. Its modest footprint (54 mm width, 78.5 mm depth, 91 mm height) makes it suitable for installations where space efficiency and reliable electrical protection are required.

Advantages

The miniature circuit breaker combines a high breaking capacity with a compact form factor, enabling dependable interruption of fault currents up to 10,000 A while occupying minimal panel space. IP20 protection reduces the risk of accidental contact with live parts during operation and maintenance. The device is engineered for predictable tripping on overloads and short circuits and integrates with standard DIN-rail mounted distribution systems.

Suitable for

  • Residential distribution boards and subpanels
  • Light-commercial electrical installations
  • Protection of branch circuits and individual loads
  • Replacement of existing miniature breakers with matching ratings and dimensions

Key specifications

  • Rated current: 40 A
  • Rated voltage: 133 V
  • Breaking capacity: 10,000 A (10 kA)
  • Degree of protection: IP20
  • Dimensions (W × D × H): 54 mm × 78.5 mm × 91 mm
  • Mounting: DIN-rail compatible

How to use

Install the breaker in the distribution panel on a compatible DIN rail, ensuring the busbar and neutral/phase connections match the device terminals and the installation is de-energized during fitting. Tighten connections to the manufacturer's recommended torque and verify polarity and conductor sizes correspond to a 40 A rated protection device. After installation, restore power and perform continuity and trip tests according to local electrical codes to confirm correct operation.

Usage recommendations

Use this miniature circuit breaker for branch circuit protection where a 40 A, 133 V rating and 10 kA breaking capacity meet system requirements. Confirm compatibility with upstream protection, cable sizing, and local regulations; schedule periodic visual inspections and functional testing as part of routine electrical maintenance.
