<p>The RCBO you&#39;re considering is a robust and reliable choice for your electrical protection needs, suitable for both industrial and commercial applications. With a rated current of 40 A, it provides effective overcurrent and earth fault protection. Designed to withstand surges up to 4 kV, this device ensures safety in environments with potential voltage spikes.</p><p>Operating at a rated voltage of 240 V and an insulation voltage of 500 V, it maintains consistent performance across varied conditions. The RCBO&#39;s breaking capacity stands at 6 kA, making it capable of handling substantial fault currents without compromising circuit integrity.</p><p>This unit features a single pole plus neutral (1P+N) configuration, optimizing space efficiency with its compact dimensions—18 mm in width, 100 mm in height, and 69 mm in depth. Its weight is just 180 g, facilitating easy installation on standard DIN rails.</p><p>Compliant with IEC standards such as IEC 61009-1 and AS/NZS 61009.1, this RCBO meets rigorous international safety requirements. It has an IP20/IP40 degree of protection rating when installed within an enclosure or distribution board that offers additional shielding.</p><p>The terminal type utilizes screw clamps with tightening torques specified at two levels: 1.2 N-m for smaller connections and up to 2.8 N-m for more robust setups. This ensures secure wiring connections whether you’re working with solid core cables ranging from 1-25 sq-mm or multi-wired cables between 1-16 sq-mm.</p><p>Electrical durability is rated at an impressive 10,000 cycles under normal use conditions while maintaining operational reliability across temperatures from -25 to +55 degrees Celsius. The curve type C characteristic allows the RCBO to handle moderate inrush currents typical in lighting circuits or small motor loads effectively.</p><p>Residual current detection is Type A sensitive to AC and pulsating DC components up to a threshold of 30 mA ensuring timely disconnection during earth faults protecting both equipment and personnel from electric shock risks.</p><p>For ease of maintenance checks or troubleshooting operations contact position indication provides clear visual cues: red signifies &#39;ON&#39; while green indicates &#39;OFF&#39;. The power supply connection located at the bottom simplifies busbar integration supporting cross sections up to Busbar:10 sq-mm Rigid:1-25 sq-mm Flexible:1-16 sq-mm enhancing versatility across various installation scenarios.</p><p>Finally built using high-quality materials finished in RAL7035 grey housing color it blends seamlessly into modern switchboards offering not only functionality but also aesthetic coherence within your electrical setup.</p>
