ABB 2CDS273001R0538

The S203M-Z32 miniature circuit breaker features a current limiting design with two distinct tripping mechanisms: a delayed thermal mechanism for overload protection and an electromechanical mechanism for short circuit protection. It supports a rated operational voltage of 400 V AC according to IEC 60898-1 and 440 V AC as per IEC 60947-2. With a breaking capacity of up to 10 kA at 230/400 V AC, it is suitable for diverse applications including residential, commercial, and industrial settings.

This model is constructed to fit on DIN rails (TH35-15 and TH35-7.5) and has a compact design with a width of 52.5 mm and a height of 88 mm, allowing for efficient space utilization. The tripping characteristic is classified as Z, making it ideal for specific load types. Furthermore, the device's environmental credentials include a recyclability rate of 80.7% and compliance with various environmental standards, enhancing its sustainability profile.

The S203M-Z32 is rated for an operational temperature range of -25 to +55 °C and offers a degree of protection rated at IP20, with an enclosure cover reaching IP40. Its robust mechanical endurance is rated for 20,000 cycles, ensuring reliable long-term performance. This circuit breaker is designed for easy installation and includes a failsafe bi-directional cylinder-lift terminal for secure connections.
