Circuit breaker C120N-C125-2 C 125A 2-pole A9N18363

Overcurrent circuit breaker is a key element of every electrical installation, providing safety and protection against overloads and short circuits. Model C120N-C125-2, with a rated current of 125A and a two-pole design, is a reliable solution for both installers and end users.

This circuit breaker is characterized by a C characteristic, which means it allows for short-term overloads without unnecessary tripping. This is particularly important when connecting devices with motors or other elements generating high starting current – such as pumps or air conditioners. This avoids unplanned downtime and ensures continuity of power supply. The rated short-circuit breaking capacity (Icn) is 10kA at 400V and 230V, and the Icu capacity according to IEC 60947-2 reaches up to 20kA at 230V and 10kA at 400V – this guarantees effective protection in the event of a failure.

• Versatile mounting: A width of 3 modules allows for easy integration with existing distribution boards.
• Wide range of wires: The ability to connect solid wires with a cross-section of 1.5 to 50 mm² and stranded wires from 1 to 35 mm² provides flexibility in choosing the appropriate cables.
• Durability in harsh conditions: The circuit breaker operates stably at temperatures from -25°C to 70°C, making it suitable for indoor and outdoor applications (with appropriate housing).
• Safety: Energy limitation class 3 and surge category 4 ensure a high level of protection for the electrical installation.
• Additional functions: The ability to disconnect the N pole simultaneously with the phase pole increases safety during maintenance and repairs.

This circuit breaker meets the standards EN 60898 and IEC 60947-2, which confirms its compliance with the highest standards of quality and safety. The degree of protection IP20 provides protection against accidental contact. Power losses are only 4.1W, which translates to efficient use of electrical energy. Installation is simple and intuitive, and the possibility of additional equipment allows you to adapt the circuit breaker to the specific needs of the installation.
