Circuit breaker iC60N-B4-1 B 4A 1-pole A9F03104

Circuit breaker iC60N-B4-1 is a member of the iC60 series, designed to protect electrical installations against the effects of short circuits and overloads. This single-pole circuit breaker with a rated current of 4A and a B characteristic is used in residential, commercial, and industrial buildings. Its design is based on IEC/EN 60947-2 and IEC/EN 60898-1 standards, which guarantees optimal parameter selection and high reliability.

Features and application

The iC60N-B4-1 circuit breaker is distinguished by the possibility of directly connecting wires of various cross-sections (from 1 to 25 mm² for solid and from 1 to 16 mm² for stranded), which simplifies installation and adaptation to different installations. The Visi-Trip optical indicator, signaling electrical tripping (white-red color), allows for quick identification of the problem and reduces repair time. Additionally, the ability to remove a single device without removing the busbar and easy removal from the DIN rail without tools significantly simplify installation work. Energy limitation class 3 provides an appropriate level of protection for the downstream circuit.

Advantages and benefits

• Versatility: Suitable for securing circuits in various types of facilities – from single-family homes to industrial buildings.
• Easy installation: The ability to connect wires of different cross-sections and quick removal from the DIN rail save time during installation.
• Fast diagnostics: The Visi-Trip indicator facilitates the location of a faulty circuit, minimizing installation downtime.
• Safety: Compliance with IEC/EN 60947-2 and IEC/EN 60898-1 standards guarantees a high level of safety.
• High durability: The rated short-circuit breaking capacity Icn is as high as 6 kA at 230 V (according to EN 60898), and Icu is 50 kA at 230 V (according to IEC 60947-2). Withstand impulse voltage Uimp is as high as 6kV.
• Durable construction: Made of high-quality materials, resistant to environmental conditions (operating temperature from -35°C to +70°C). Protection degree IP20 provides basic protection against touch and ingress of solid objects.
• Cost optimization: Energy limitation class 3 allows reducing the costs of securing the downstream circuit.

The B characteristic of the circuit breaker causes it to react quickly to short-term overloads, but at the same time, it tolerates inrush currents of inductive devices well – which is particularly important when protecting lighting or socket circuits in residential buildings. Power losses of only 2.4 W minimize energy consumption by the circuit breaker itself.
