ABB 2CDS253001R0337

The S203-K4 Miniature Circuit Breaker is designed to ensure effective overload and short circuit protection through its dual tripping mechanisms: a delayed thermal mechanism for overloads and an electromechanical mechanism for short circuits. It features a rated operational voltage of up to 440 V AC and can handle breaking capacities of 6 kA at both 230 V and 400 V AC.

This device 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. The product's compact design allows it to be mounted on standard DIN rails, specifically TH35-15 and TH35-7.5 sizes, and can be installed in any position.

With a net weight of 0.336 kg, the S203-K4 is constructed from materials compliant with insulation group II standards and has a housing that meets RAL 7035 specifications. Its environmental resilience is highlighted by an operational temperature range from -25 °C to +55 °C and a storage temperature of -40 °C to +70 °C.

The device also includes features such as a red ON and green OFF contact position indication, ensuring clear operational status. Furthermore, the miniature circuit breaker is designed for easy wiring with various connecting capacities, accommodating flexible and rigid cables.
