Circuit breaker Acti9 iC60N-D20-3 D 20A 3-pole A9F05320

iC60N Circuit Breakers – Protection for Electrical Installations

The iC60N-D20-3 D 20A 3-pole circuit breaker is part of the Acti9 range, designed for effective protection against short circuits and overloads in electrical installations. This device combines adaptability for use in residential, commercial, and industrial buildings, meeting the requirements of IEC/EN 60898-1 and IEC/EN 60947-2.

This model, with catalog number A9F05320, is characterized by a rated current of 20A and has a D tripping characteristic, which means it reacts with a delay to short-term current surges – an ideal solution for devices with motors or other inductive loads. The rated short-circuit breaking capacity (Icn) is 6kA at 230V and 400V, and the Icu capacity reaches 10kA at 400V and up to 20kA at 230V, providing a high level of safety.

The circuit breaker's design has been carefully thought out for ease of installation and operation. The ability to directly connect wires with a cross-section from 1 to 25 mm² (solid) or from 1 to 16 mm² (stranded) simplifies installation. Additionally, the presence of the VisiTrip optical indicator informs about the tripping of the circuit breaker, and the VisiSafe indicator signals the state of the contacts – a green color indicates open contacts and the possibility of safely performing maintenance work.

• Versatility: Compliance with EN/IEC 60898-1 and EN/IEC 60947-2 standards allows use in various types of installations – from domestic to industrial.
• High resistance: Rated impulse withstand voltage of 6kV provides protection against overvoltages.
• Easy installation: The ability to remove a single device without removing the busbar significantly speeds up service work.
• Safety: VisiTrip and VisiSafe indicators facilitate identification of damage and ensure safe working conditions.
• Wide temperature range: Operation in a temperature range from -35°C to +70°C allows use in difficult environmental conditions.

iC60N circuit breakers are not only a protective element but also a solution for optimizing the operation of electrical installations thanks to advanced diagnostic functions and ease of use. An energy limitation class of 3 further improves the cost of protecting the downstream circuit.
