Legrand 410965 circuit breaker Miniature circuit breaker Type A 2 2 module(s)

The Legrand 410965 is a Type A miniature circuit breaker designed for 230 V single-phase electrical installations. Rated for 16 A nominal current and occupying up to 2 DIN-module widths, this compact device provides reliable protection against overloads and short circuits in residential and light-commercial distribution boards. With a lightweight construction and standardized DIN-rail mounting, it integrates into modular panels while maintaining circuit continuity and safety.

Advantages

The miniature circuit breaker delivers selective tripping for both resistive and moderately capacitive or inductive loads thanks to its Type A characteristics. Its compact two-module footprint conserves panel space while allowing straightforward installation on standard DIN rails. Built to meet common electrical safety standards, the device offers consistent thermal-magnetic protection, rapid response to short-circuit conditions, and manual switch control for circuit isolation during maintenance.

How to use

Install the miniature circuit breaker on a standard DIN rail inside a properly rated distribution enclosure. Ensure power is disconnected before wiring. Connect the phase conductor to the breaker input terminal and the load conductor to the output terminal, tightening terminals to the torque recommended by the electrical code or installer guidelines. After wiring, switch the breaker to the ON position and verify correct operation by applying a controlled load; the device should remain closed under normal current and trip under overload or short-circuit conditions. Use proper auxiliary devices or interlocks if required by the installation.

Recommendations

Select a Type A breaker when circuits may include devices with small residual currents or nonlinear electronic components; this ensures compatibility and reliable tripping behavior. Confirm that the 16 A rating matches the calculated load and coordination requirements in the distribution board. For safe operation, have installations inspected and commissioned by a qualified electrician and follow local electrical codes for tightening torques, conductor sizes, and protective clearances.
