Description

<p>This RCBO (Residual Current Circuit Breaker with Overcurrent Protection) is engineered to provide reliable protection for electrical circuits, combining the functionality of an MCB and RCD in one compact unit. It is designed for both industrial and commercial applications, ensuring safety against overloads, short-circuits, and earth faults.</p><p>With a rated current of 10 A, this device offers robust protection at a breaking capacity of 10 kA. Its 4-pole configuration makes it suitable for three-phase systems with a neutral conductor. The RCBO operates efficiently across a range of voltages; its rated voltage stands at 415 V while the insulation voltage is rated at 500 V.</p><p>The product boasts a rated impulse withstand voltage of 4 kV, demonstrating resilience against transient overvoltages. This feature ensures the integrity of your system during unexpected power spikes or lightning strikes. Additionally, its degree of protection is classified as IP2X, safeguarding against solid foreign objects greater than 12.5 mm in diameter.</p><p>In terms of physical dimensions, this RCBO measures 71 mm in width, 85 mm in height, and has a depth of 69 mm. Despite its compact size, it maintains substantial durability with an electrical endurance up to 10,000 cycles and mechanical robustness that ensures long-term reliability under frequent use.</p><p>The device supports various cable cross-sections: from single-core solid wires to multi-wired cables ranging between 1-25 sq-mm and busbar connections up to 10 sq-mm. This versatility simplifies installation across different setups without compromising on connection integrity.</p><p>Rated for operation within an ambient temperature range from -25&amp;#176;C to +55&amp;#176;C and featuring overvoltage category III classification means it&amp;#39;s well-suited for environments subject to moderate pollution levels (Degree of Pollution: IP2). Furthermore, the residual current type A provides effective detection against sinusoidal AC currents as well as pulsating DC components.</p><p>Compliant with international standards including IEC/EN 61009-1 &amp;amp; IEC/EN 61009-2-1 certifications assures adherence to strict safety regulations—critical when selecting protective devices in Australia’s diverse climatic conditions where reliability cannot be compromised.</p><p>Its operating characteristic is instantaneous with undelayed earthing switch type allowing immediate response upon fault detection thereby reducing potential hazards significantly enhancing user confidence knowing their installations are protected by high-quality equipment capable enough even amidst challenging scenarios encountered frequently within industrial settings today!</p>
