Overcurrent circuit breaker, 1P+N, B characteristic, 6A, 6kA, AC | S201-B6NA 2CDS251103R0065

Overcurrent circuit breaker for protecting electrical installations.

This S200 series circuit breaker from ABB is a reliable device designed to protect electrical circuits against overloads and short circuits. It is ideal for both home and commercial installations, ensuring safety and long-term operation of devices. The 1P+N (single pole with neutral wire) design allows for effective protection in single-phase and three-phase systems.

Characteristics and application

The circuit breaker is characterized by a B characteristic, which means it is particularly well suited for protecting circuits with receivers with high inrush current – such as motors, transformers or devices with heating elements. This minimizes the risk of unnecessary tripping of the device during start-up. The rated short-circuit breaking capacity of 6kA (at 230V) and 10kA (at 400V) guarantees effective intervention in the event of a failure. DIN rail mounting facilitates quick and easy installation.

Key features and benefits

• Wide range of applications: Suitable for securing circuits in residential, commercial and industrial buildings.
• High reliability: Ensured by a renowned manufacturer – ABB.
• Protection against overloads and short circuits: Protects the circuit from damage caused by incorrect operation of the installation or connected devices.
• B characteristic: Ideal for circuits with receivers with high inrush current, such as motors or transformers – avoids unnecessary tripping.
• Breaking capacity 6kA/10kA: Guarantees effective disconnection of the circuit in the event of a short circuit.
• Compact dimensions: 2 module width allows for efficient use of space in the distribution board.
• Wire cross-section: Possibility to connect wires with a cross-section from 0.75 mm² to 25 mm², which provides flexibility when selecting wires for a specific application.
• Operating temperature: Wide operating temperature range (-25°C to +55°C) allows the circuit breaker to be used in various environmental conditions.
• Protection class IP20: Provides protection against touching with fingers and against the ingress of solid objects larger than 12.5 mm – standard protection for devices mounted inside electrical cabinets.

Additionally, the circuit breaker has energy limitation class 3, which means it is able to limit short-circuit energy, minimizing potential damage to the installation and connected devices. Compliance with IEC/EN 60898-1 and IEC/EN 60947-2 standards confirms its safety and high quality of workmanship.
