Product information

Description

Schneider Electric A9F04440 (iC60N-C40-4) is a 4-pole miniature circuit breaker with a type C thermal-magnetic trip characteristic and a rated current of 40 A. Designed for overload and short-circuit protection in multi-phase electrical installations, it fits standard DIN-rail distribution boards and provides simultaneous disconnection of all poles. The device has IP20 degree of protection and a compact module width suitable for residential and commercial distribution panels.

Advantages

The A9F04440 offers coordinated common-trip protection for three-phase circuits with neutral, reducing the risk of unsafe phase imbalance during fault conditions. Its compact footprint and standard DIN-rail mounting make it easy to integrate into existing modular switchboards. Compatibility with common accessories such as auxiliary contacts and mounting aids allows flexible configuration without complex panel modifications.

Suitable for

Protection of three-phase circuits with neutral in residential and commercial distribution boards
Overload and short-circuit protection for lighting, heating and motor feeds compatible with a type C curve
Applications requiring simultaneous disconnection of all poles for safety and maintenance
Integration in compact DIN-rail electrical panels and modular switchboards

When it may not be suitable

This circuit breaker is not intended for circuits with high inrush currents where a D or K trip curve is typically required to prevent nuisance tripping, for example some large motors or highly inductive loads. It should not be used in place of protection devices that must meet specific industrial certifications or specialized characteristics mandated by particular applications.

Key specifications

Poles: 4-pole common trip
Rated current: 40 A
Tripping characteristic: Type C (thermal-magnetic)
Degree of protection: IP20
Mounting: DIN-rail
Application: overload and short-circuit protection for multi-phase circuits

How to use

Mount the breaker on a standard DIN-rail in the distribution board, ensuring correct orientation and secure connections for all line and load terminals. Use conductors with appropriate cross-section and tighten terminals to the manufacturer’s torque values for 40 A service. After wiring, perform insulation and continuity checks and verify correct phase sequence where required before energising. Coordinate with upstream and downstream protective devices to maintain selectivity.

What to consider before purchase

Confirm that a type C trip curve and 40 A rated current suit the protected loads and their inrush characteristics
Ensure interrupting capacity and IP20 degree meet local installation requirements and panel conditions
Verify available space and DIN-rail layout to accommodate a 4-pole device
Check compatibility with auxiliary accessories if remote signalling or shunt trip functions are needed

Usage recommendations

Coordinate the A9F04440 with upstream protection and assess motor starting or other high inrush devices to avoid nuisance trips; where necessary select a different trip curve or add appropriate protective devices. Perform regular inspections of terminals and periodic testing in accordance with local electrical codes.
