Installation and Person Protection – ABB DSH201 C10 AC30 Residual Current Breaker with Overcurrent Protection

This single-pole plus neutral (1P+N) residual current breaker with overcurrent protection from ABB's DSH201 series combines overcurrent and residual current protection, providing comprehensive protection in electrical installations. It is a key safety element that protects both people and devices from the effects of short circuits, overloads, and leakage currents. The C characteristic makes it ideal for circuits with devices that draw higher current at start-up, such as motors.

This breaker is designed to operate in installations with a voltage of 230V AC and a rated current of 10A. The short-circuit interrupting capacity of 6kA guarantees effective disconnection of the circuit in the event of a failure. Additionally, the leakage current sensitivity of 30mA (AC type) ensures a quick response in the event of an electric shock hazard.

Mounting and Application

The DSH201 breaker is mounted on a DIN rail and occupies a width of two modules (36mm), allowing for efficient use of space in the distribution board. It is intended for use in circuits with a conductor cross-section of up to 25 mm², both solid and stranded. Thanks to the mechanical lock, it prevents accidental switching on of the breaker after tripping – increasing safety during maintenance or repair work. It can be used in residential installations, public buildings, and anywhere that requires high reliability and protection against electrical hazards.

Key Features and Benefits:

• Comprehensive protection: Combination of overcurrent protection (C characteristic) and residual current protection (30mA AC) in one device.
• Fast response: Immediate tripping characteristic ensures instantaneous disconnection of the circuit in the event of a failure.
• Safety: Mechanical lock prevents accidental re-engagement of the breaker after tripping.
• Versatility: Designed for use with conductors with a cross-section of up to 25 mm².
• Compact dimensions: 2-module width makes it easy to install even in tight distribution boards.
