ABB 2CDS253001R0105

The S203-B10 Miniature Circuit Breaker is engineered for effective overload and short circuit protection in various applications. It features a rated current of 10 A and is compliant with standards such as IEC/EN 60898-1 and UL 1077, ensuring compatibility across residential, commercial, and industrial settings.

This device incorporates two distinct tripping mechanisms: a delayed thermal mechanism for overloads and an electromechanical mechanism for short circuits. The breaking capacity reaches up to 6 kA at 230/400 V AC, validating its robustness in handling fault conditions.

With a compact design, the breaker occupies three modular spacings, measuring 52.5 mm in width and 88 mm in height, and is mountable on standard DIN-rails. Its operational temperature range spans from -25 °C to +55 °C, making it suitable for diverse environmental conditions.

The S203-B10 also supports bottom-fitting auxiliary contacts for enhanced space efficiency. Its environmental product declaration indicates adherence to sustainable practices, boasting a recyclability rate of 80.7% as per EN45555 standards. This miniature circuit breaker not only meets high operational standards but also contributes to resource conservation.
