18365 Circuit breaker С120N 3П 80A C /SCHNEIDER/

Circuit breaker C120N 3P 80A type C 10kA /Schneider Electric/ The three-pole circuit breaker of the C120N industrial series from Schneider Electric is designed to protect three-phase power circuits against overload and short-circuit currents. The model with a rated current of 80 Amperes belongs to the high-power modular devices capable of operating in networks with high prospective fault currents. Thanks to its reinforced design and high breaking capacity of 10 kA, this breaker provides reliable protection of distribution networks in commercial buildings and at industrial facilities. Technical parameters Brand: Schneider Electric Series: C120N (Acti9 range) Article number: 18365 Number of poles: 3 (3P) Rated current: 80 A Tripping curve: C Breaking capacity: 10 kA (according to IEC 60947-2) Rated voltage: 380–415 V AC Mounting type: DIN rail Width: 4.5 modules (81 mm) Degree of protection: IP20 Design features The C120N series breaker has an enlarged frame size (1.5 modules per pole), which is necessary to accommodate a powerful arc-quenching system and to ensure effective cooling of the main contacts. The housing is made of high-strength plastic resistant to thermal shock. The device is equipped with a fast-closing mechanism, which extends the service life of the contacts through rapid closing. The terminals of the device allow large cross-section cables to be connected (up to 50 mm² for flexible wire), ensuring secure fixing and minimal heating at the connection points. Advantages High breaking capacity: 10 kA allows the breaker to be used in distribution boards located close to powerful transformer substations. Industrial reliability: The C120N series is designed for harsh operating conditions and has increased electrical endurance. Safety: The green VisiSafe strip guarantees complete safety during maintenance by confirming the physical opening of the contacts. Synchronous tripping: In the event of a fault on one of the phases, the mechanism is guaranteed to disconnect all three poles, preventing failure of three-phase motors. Compatibility with Acti9: Additional accessories such as auxiliary contacts and remote releases can be fitted. Field of application In Almaty, Schneider Electric C120N 80A circuit breakers are used as incoming or feeder devices in main distribution boards (ГРЩ) and control cabinets. They are ideally suited for protecting powerful ventilation systems, chillers, lift equipment and production machine tools. The type C characteristic ensures stable operation of circuits with inductive loads, allowing inrush currents to be handled successfully without nuisance tripping of the protection.
