Circuit breaker C120N-C80-3 C 80A 3-pole A9N18365

Overcurrent protection switch – reliable protection for electrical installations

This three-pole overcurrent switch from the Acti 9 series, with a rated current of 80A, is a key element of every safe and efficient electrical installation. Designed by Schneider Electric, it provides effective protection against overloads and short circuits, minimizing the risk of damage and fires. Characteristic C makes it ideal for circuits with devices generating surge currents, such as motors or transformers – it allows it to react more slowly to short current spikes, while quickly activating in the event of a prolonged overload.

Solid construction and technical parameters

The C120N-C80-3 switch is characterized by high quality and durability. Mounting on a TH35 rail allows for quick and easy installation in the distribution board. A width of 4.5 modules provides compact dimensions, which is particularly important in tight spaces. The rated short-circuit breaking capacity (Icn) is 10kA at 230V and 400V, and the Icu capacity reaches up to 20kA at 230V, guaranteeing safety even in the event of serious failures. The rated insulation voltage Ui is 500V, and the rated impulse withstand voltage Uimp is 6kV – this confirms high resistance to working conditions.

• Rated current: 80A – suitable for circuits with higher power demand.
• Tripping characteristic: C – ideal for protecting circuits with devices generating surge currents.
• Number of poles: 3 – provides comprehensive protection for three-phase installations.
• Short-circuit breaking capacity (Icn): 10kA (230V/400V) – high effectiveness in the event of short circuits.
• Short-circuit breaking capacity (Icu): up to 20kA (230V) - additional protection against the effects of short circuits.
• Width: 4.5 modules – compact dimensions make it easy to install in a limited space.
• Degree of protection: IP20 - protection against contact with a finger and solid objects larger than 12.5 mm.

Application and compliance with standards

This switch finds wide application in both residential, commercial and industrial installations. It will be perfect for protecting lighting circuits, socket circuits and electrical devices with higher power consumption. It meets the requirements of EN 60898 and IEC 60947-2 standards, which guarantees its safety and reliability. The energy limitation class is 3 and the surge category is IV - this provides adequate protection against the effects of overvoltages in the electrical installation. The conductor cross-section from 1mm² to 50mm² provides great flexibility when selecting conductors supplying energy to the switch.
