2CSR275040R1204 ABB

The ABB 2CSR275040R1204 is a DS201 series miniature differential circuit breaker (MCB) meticulously engineered to provide comprehensive protection against short circuits, overloads, and earth fault currents. This 1P+N (one pole plus neutral) device is designed for single-phase AC systems, ensuring reliable performance in residential, commercial, and industrial applications. With a C-curve tripping characteristic, it offers a balance between sensitivity and immunity to nuisance tripping, making it suitable for circuits with moderate inrush currents. The MCB has a rated current of 20A and a sensitivity of 30mA, providing effective protection against potentially dangerous earth leakage currents. Its breaking capacity of 10kA ensures that it can safely interrupt high fault currents, preventing damage to equipment and minimizing the risk of electrical hazards. The DS201 series is known for its compact design, ease of installation, and compliance with relevant international standards. This particular model incorporates both overload and short-circuit protection, as well as residual current protection in a single compact unit. This MCB is designed to enhance safety and reliability in electrical installations. It is suitable for a wide range of applications where reliable protection against electrical faults is essential.
