£238.00
The ABB 2CSR255180R1404, also known as the DS201 C40 A30, is a high-quality residual current circuit breaker with overcurrent protection (RCBO) designed to protect single-phase electrical installations from overloads, short circuits and earth leakage faults. As part of the trusted ABB DS201 series, it combines the functions of a miniature circuit breaker and residual current device in one compact unit.
Designed for modern electrical installations, this Type A RCBO detects both sinusoidal AC and pulsating DC residual currents, making it suitable for circuits supplying electronic equipment and appliances. Its integrated protection enhances electrical safety while helping ensure compliance with current wiring regulations.
With a rated current of 40 A, a C-curve tripping characteristic and a 230 V AC operating voltage, the DS201 C40 A30 is ideal for residential, commercial and light industrial applications. Its compact 1P+N DIN rail design allows simple installation within consumer units and distribution boards.
The ABB DS201 C40 A30 protects electrical circuits by automatically disconnecting the supply whenever overload, short-circuit or earth leakage conditions are detected. Combining multiple protection functions within one device simplifies installation while reducing the space required inside electrical distribution boards.
Its Type A residual current detection makes it particularly suitable for circuits supplying appliances and equipment containing electronic components, offering dependable protection in residential, commercial and industrial environments.
