Product information

Description

Schneider Electric A9F03340 is a miniature circuit breaker designed for DIN-rail electrical distribution. Rated for 40 A and 133 V with a breaking capacity of 10 kA, this device provides overcurrent protection in compact installations. With IP20 protection and a narrow 54 mm width, it is suitable for residential and light-commercial panels and control cabinets where space efficiency is required.

How to use

Mount the miniature circuit breaker on a compatible DIN rail inside the distribution board, ensuring the device orientation matches other protective devices. Connect the supply and load conductors to the designated terminals, observing correct tightening torques and conductor sizing per local regulations.

After installation, perform standard insulation and continuity checks and operate the breaker manually to confirm mechanical function.

Usage recommendations

Use this breaker in circuits where 40 A overcurrent protection and a 10 kA breaking capacity are suitable.
