BTicino FN81NC40 - Magnetothermal 1P+N Curve C 40A 6kA

BTicino FN81NC40 - Thermal-magnetic circuit breaker 1P+N, curve C, In= 40A, Icn= 6kA, Vn= 230 Va.c., 2 modules

The BTicino FN81NC40 thermal-magnetic circuit breaker is designed to offer reliable protection against overloads and short circuits in electrical circuits. Here are its main features:

• Curve of intervention: The circuit breaker is curve C, providing sensitive protection against moderate overloads and effective protection against short circuits of higher intensity.
• Rated current (In): The rated current is 40A, indicating the maximum current that can circulate in the circuit without activating the protection.
• Interrupting capacity (Icn): The device has an interrupting capacity of 6kA, which means it can safely interrupt short-circuit currents up to this value.
• Voltage rating (Vn): Designed to operate at voltages of 230 Vac, representing the maximum voltage of the circuit in which it can be installed.
• Dimensions: The circuit breaker occupies 2 modules of space inside the switchboard.
