<p>The RCBO is a robust solution tailored for industrial and commercial applications, ensuring reliable circuit protection with its comprehensive features. Designed to handle the demands of modern electrical systems, this device combines overcurrent protection and residual current detection in one compact unit.</p><p>With a rated current of 25 A, it efficiently manages electrical loads while maintaining safety standards. The RCBO operates at a rated voltage of 400/415 VAC and supports both 50 and 60 Hz frequencies, making it versatile across various installations. It boasts an impressive short circuit capacity of 10 kA, providing substantial resilience against potential faults.</p><p>This device adheres to rigorous standards such as IEC 61009-1, IEC 61009-2-2, and AS/NZS 61009-1, ensuring compliance with international safety regulations. Its rated impulse withstand voltage stands at 4 kV, while the insulation voltage reaches up to 500 V—both contributing to its robust protective capabilities.</p><p>Physically compact yet powerful, the RCBO measures 53.4 mm in width, with a height of 117.5 mm and depth of 71.6 mm. Despite its solid construction weighing in at just over half a kilogram (0.549 kg), it maintains ease of installation within tight spaces.</p><p>The degree of protection is classified as IP20, suitable for indoor environments where dust ingress is limited but no water exposure occurs. The pollution degree marked as IP2 indicates moderate environmental conditions are acceptable without compromising performance.</p><p>Offering flexibility in connections, this RCBO accommodates cable cross sections ranging from single-core solid wires (1-25 sq-mm) to multi-wired configurations (up to four wires totaling between one and sixteen sq-mm). Additionally, busbar connectivity allows for up to ten square millimeters.</p><p>Its operating characteristics are instantaneous due to the undelayed earthing switch type—a critical feature for rapid response during fault conditions—and ensures minimal disruption by quickly isolating affected circuits.</p><p>The curve type C characteristic further enhances suitability across diverse load types by allowing higher inrush currents typically seen in motor startups or similar inductive loads without unnecessary tripping events occurring prematurely under normal operation scenarios.</p><p>Engineered with an ambient temperature range from -5&#176;C up through +55&#176;C means adaptability even amidst fluctuating climatic conditions often encountered onsite; thus extending lifecycle durability alongside electrical endurance reaching upward towards ten thousand operational cycles before maintenance considerations arise again naturally over time usage span expectedly so here too!</p><p>For those seeking peace-of-mind via enhanced sensitivity against earth leakage incidents specifically targeting Type A residual currents—this model delivers precisely that functionality effectively limiting any risk associated therein down beneath thirty milliamperes rating threshold accordingly indeed!</p>
