Description
The Acti9 C120N (A9N18358) is a robust low-voltage miniature circuit breaker designed to meet both EN/IEC 60898-1 industrial standards and EN/IEC 60947-2 residential standards. This 1-pole MCB delivers dependable protection against short circuits and overloads with a 100A rated current and C tripping curve.
Its green contact indicator ensures clear visual confirmation of circuit status, enhancing safety during maintenance. With high overvoltage withstand capacity, limitation class 3 for cost-effective downstream protection, and long endurance (up to 5,000 electrical cycles and 20,000 mechanical cycles), it’s built for performance and durability.
The compact DIN rail mount design (3 × 9mm pitches width) makes installation simple, while its IP20 terminal protection ensures operator safety. Suitable for use in demanding environments, it operates from −25°C to +70°C and stores from −40°C to +85°C.
