ABB 2CDS252001R0217

The Miniature Circuit Breaker operates with a tripping characteristic of K and is designed for both residential and industrial applications. It incorporates two distinct tripping mechanisms: a delayed thermal mechanism for overload protection and an electromechanical mechanism for short circuit protection. The device complies with IEC/EN 60898-1 and IEC/EN 60947-2 standards, ensuring reliability and safety.

This model supports a rated operational voltage of up to 440 V AC and can handle a maximum operational voltage of 125 V DC. It provides a rated short-circuit capacity of 6 kA and an ultimate breaking capacity of 20 kA at 230 V AC. The MCB is constructed for mounting on DIN Rail TH35 and is suitable for various mounting positions.

With an ambient temperature operation range of -25 to +55 °C and storage capabilities from -40 to +70 °C, this circuit breaker is designed to withstand diverse environmental conditions. The unit is compliant with RoHS directives and is rated for a pollution degree of 3, making it suitable for challenging environments.

For ease of installation, the MCB features a screw terminal design with a tightening torque of 2.8 N·m. It is equipped with a contact position indication (red ON / green OFF) and has an electrical endurance of 20,000 AC cycles, ensuring long-term performance.

Additional features include a power loss of 2.5 W at rated operating conditions and a mechanical endurance of 20,000 cycles. The product dimensions include a width of 35 mm and...
