ABB 2CDS253001R0084

The Miniature Circuit Breaker (MCB) is engineered for three-phase systems, featuring a tripping characteristic of C and a rated current capacity of 8 A. Designated Code: S203-C8. This device integrates two distinct tripping mechanisms: a delayed thermal mechanism for overload protection and an electromechanical mechanism for short circuit protection, ensuring reliable operational safety.

With a rated operational voltage of up to 440 V AC and a breaking capacity of 6 kA, this MCB is suitable for various applications, including residential, commercial, and industrial settings. It complies with relevant standards such as IEC/EN 60898-1 and IEC/EN 60947-2, making it a versatile choice for electrical installations.

The MCB is mountable on DIN rails (TH35-15 and TH35-7.5) and accommodates a wide range of wire sizes, enhancing its adaptability in different environments. Its compact design, measuring 52.5 mm in width and 69 mm in depth, coupled with a weight of 0.336 kg, facilitates efficient use of space in electrical panels.

For enhanced functionality, bottom-fitting auxiliary contacts can be added to optimize space usage by 50%. This device also exhibits a robust environmental profile, with a recyclability rate of 80.7%, adhering to sustainability practices.
