ABB S203MT-C32 Miniature Circuit Breaker 10 kA 3-P 32A 400V C-Curve

<p>When it comes to selecting a reliable circuit breaker for industrial and commercial applications, understanding the technical specifications is crucial. This three-pole circuit breaker is engineered to meet demanding environments with precision and safety in mind.</p><p>The breaker handles a rated current of 32 A, making it suitable for various medium-load applications. It boasts a rated impulse withstand voltage of 4 kV, ensuring resilience against transient overvoltages typically caused by lightning or switching surges. With a rated insulation voltage of 440 V and a rated operational voltage of 400 V, this device fits seamlessly into standard electrical systems.</p><p>Efficiency and safety are further highlighted by its power loss rating of just 11.1 W, which helps maintain energy efficiency while reducing heat generation during operation. The breaking capacity stands at an impressive 11.3 kA, offering robust protection against short circuits.</p><p>This circuit breaker&amp;#39;s IP20 degree of protection indicates that it is safeguarded against solid objects larger than 12 mm but should be installed in enclosures if exposure to moisture or dust is anticipated.</p><p>Installation flexibility is enhanced by the screw clamp terminal type that supports secure connections with a tightening torque requirement of 2.8 N-m. Its compact dimensions—52.5 mm in width, 88 mm in height, and 69 mm in depth—allow for space-efficient integration into panels or distribution boards.</p><p>Compliance with international standards IEC/EN 60898-1 and IEC/EN 60947-2 ensures reliability across global markets. Designed for both residential and commercial settings, this breaker operates efficiently within ambient temperatures ranging from -25&amp;#176;C to +55&amp;#176;C and can be stored safely between -40&amp;#176;C to +70&amp;#176;C without performance degradation.</p><p>The C curve type characteristic provides optimal tripping behavior for typical load conditions found in lighting circuits or general-purpose outlets where moderate surge currents occur without nuisance tripping.</p><p>Durability isn&amp;#39;t compromised either; with an electrical durability rating of up to 20,000 cycles, you can expect long-lasting performance even under frequent use conditions.</p><p>Finished in RAL 7035 grey housing color, this product offers aesthetic consistency with other industrial components while maintaining high visibility for ease of identification during maintenance checks.</p>
