Overcurrent circuit breaker, 1P+N, B characteristic, 10A, 6kA, AC | S201-B10NA 2CDS251103R0105

Reliable protection for electrical installations – ABB S201-B10NA circuit breaker

Product description

This single-pole circuit breaker with an additional neutral pole (1P+N) is a key element of every safe electrical installation. Designed by the renowned company ABB, it provides effective protection against overloads and short circuits in circuits with a rated current of 10A. It is characterized by high reliability and durability, making it an ideal choice for both professional installers and demanding users.

The S201-B10NA circuit breaker is characterized by a B characteristic, which means it is particularly well suited for protecting circuits with receivers with high inrush current – for example, electric motors or transformers. This avoids unnecessary tripping of the circuit breaker when starting these devices. The rated short-circuit breaking capacity of 6kA (at 230V and 400V) and 10kA (at 230V) guarantees safety in the event of serious disturbances in the network.

Solid construction and easy installation

The circuit breaker has been designed with convenience of installation and operation in mind. Its compact dimensions (2 modules wide) allow for efficient use of space in the distribution board. The ability to connect multi-wire cables with a cross-section of 0.75 to 25 mm² and solid-core cables from 0.75 to 35 mm² provides flexibility in choosing the supply cables. The IP20 degree of protection prevents accidental contact, and the wide operating temperature range (-25°C to +55°C) allows it to be used in various environmental conditions.

• B characteristic: Ideal for protecting circuits with receivers with high inrush current – motors, transformers, etc. Allows you to avoid unnecessary tripping of the circuit breaker when starting devices.
• High short-circuit breaking capacity: Ensures safety in the event of serious disturbances in the network (6kA at 230V/400V, 10kA at 230V).
• Compact dimensions: Occupies only 2 modules in the distribution board, saving valuable space.
• Wide range of cable cross-sections: Allows connection of multi-wire cables (0.75-25 mm²) and solid-core cables (0.75-35 mm²).
• Versatile application: Suitable for protecting circuits with a rated voltage of 230V AC and a frequency of 50/60 Hz.
• Safety of use: IP20 degree of protection prevents accidental contact.
• Durability and reliability: Product from the renowned company ABB, guaranteeing long-term and trouble-free operation.

The S201-B10NA circuit breaker meets the requirements of EN 60898 and IEC 60947-2 standards, confirming its compliance with applicable safety standards. The energy limitation class is 3, and the rated insulation voltage Ui is 440V. Power losses are only 4.2W, which translates to energy efficiency of the installation. Additionally, the possibility of mounting additional equipment increases the functionality of the device and allows it to be adapted to individual user needs.
