ABB 2CDS273001R0011

The S203M-D1 miniature circuit breaker is part of the S200M series, known for its current limiting capabilities. It utilizes two distinct tripping mechanisms: a delayed thermal tripping mechanism for overload protection and an electromechanical mechanism for short circuit protection. This model is compliant with IEC/EN 60898-1 and IEC/EN 60947-2 standards, making it suitable for various applications, including residential, commercial, and industrial settings.

With a rated operational voltage of 400 V AC and a rated short-circuit capacity of 10 kA at 400 V AC, this circuit breaker is engineered to handle demanding electrical environments. Its compact design, measuring 52.5 mm in width and 88 mm in height, allows for installation on standard DIN rails (TH35-15 and TH35-7.5 as per IEC 60715). The S203M-D1 also features a robust dielectric withstand capability of 4 kV and ensures operational integrity across a temperature range of -25 °C to +55 °C.

The device includes a contact position indicator and supports various connection capacities, including flexible and rigid conductors. Additionally, it is designed with environmental considerations in mind, achieving a recyclability rate of 80.7% according to EN45555 standards. The S203M-D1 is a reliable choice for users needing effective circuit protection solutions.
