Residual current circuit breaker, 1P+N, B characteristic, 16A, 6kA, 30mA, AC, instantaneous DS201 B16 AC30 2CSR255080R1165

Protection and safety in your electrical installation

This DS201 B16 AC30 residual current circuit breaker with overcurrent protection from ABB is a reliable device that combines the functions of an overcurrent and residual current circuit breaker. It provides comprehensive protection of electrical circuits against overloads, short circuits and leakage currents, minimizing the risk of electric shock and equipment damage. It is an ideal solution for both home and commercial installations where high efficiency and reliability of protection are required.

Functionality and application

This circuit breaker, with characteristic B, is perfect for circuits with devices with high inrush current – such as motors or transformers. Characteristic B allows it to react more slowly to short current surges, which prevents unnecessary tripping. The rated current of 16A makes it suitable for protecting typical lighting and socket circuits. In addition, the sensitivity to residual current of 30mA guarantees a quick response in the event of a dangerous leakage current to earth. The device is designed for mounting on a DIN rail and occupies a width of two modules, which facilitates its integration with existing electrical infrastructure.

Key features and benefits

• Combined function: One device provides protection against overload, short circuit and leakage currents – saving space in the distribution board and simplifying installation.
• Characteristic B: Provides optimal protection for circuits with devices with high starting current, minimizing the risk of false tripping.
• High breaking capacity: The rated breaking capacity of 6kA guarantees effective disconnection of the circuit in the event of a short circuit.
• AC sensitivity: Effectively detects sinusoidal leakage currents to earth, ensuring user safety.
• DIN rail mounting: Enables quick and easy mounting and removal of the device.
• Compact dimensions: A width of 2 modules allows for efficient use of space in the distribution board.
• Compliance with standards: The product meets strict safety standards, ensuring high quality and reliability.
• Designed for 1P+N installations: Provides protection for both the phase and neutral conductors.

Technical parameters in practice

The DS201 B16 AC30 circuit breaker has been designed with durability and reliability in mind. Its resistance to environmental conditions (operating temperature from -25°C to 55°C) and high degree of protection (IP20) guarantee its proper operation even in difficult conditions. The rated insulation voltage Ui of 500V ensures safe use in various electrical installations. In addition, the energy limitation class 3 indicates its ability to withstand voltage surges of 4kV. The cross-section of the multi-wire connecting cable from 0.75mm² to 16mm² provides flexibility when connecting cables of different thicknesses.
