ABB 2CDS273001R0044

The S203M-C4 miniature circuit breaker features a three-pole configuration and is designed for current limiting applications. It utilizes two different tripping mechanisms: a delayed thermal mechanism for overload protection and an electromechanical mechanism for short circuit protection. This breaker is compliant with IEC/EN 60898-1 and IEC/EN 60947-2 standards, making it suitable for various environments including residential, commercial, and industrial applications.

With a rated operational voltage of 400 V AC and a rated short-circuit capacity of 10 kA, this device ensures reliable protection against electrical faults. The breaking capacity can handle up to 10 kA at both 230 V and 400 V AC, while the rated ultimate short-circuit breaking capacity is 25 kA at 230 V AC and 15 kA at 400 V AC. The circuit breaker also supports a wide operational voltage range, from a minimum of 12 V AC to a maximum of 440 V AC.

Installation is facilitated by mounting on standard DIN rails (TH35-15 and TH35-7.5), and it can be positioned in any orientation. The compact design has a width of 52.5 mm, a height of 88 mm, and a depth of 69 mm, allowing for efficient use of space. An auxiliary contact can be added to save additional space.

Environmental considerations have been taken into account, with a recyclability rate of 80.7% according to EN45555 standards, and the product is designed for operation in ambient temperatures ranging from -25 °C to +55 °C. The degree of protection is rated at IP20,...
