<p>When selecting an RCBO for your industrial or commercial applications, precision and reliability are key. This 40 A RCBO is designed to meet demanding requirements, ensuring safety and efficiency in electrical systems.</p><p>Rated at a current of 40 A with a rated voltage of 240 V, this device effectively balances protection and performance. It boasts a robust breaking capacity of 15 kA, making it suitable for environments where high fault levels might occur. The rated impulse withstand voltage stands at 4 kV, providing resilience against transient overvoltages.</p><p>The unit&#39;s compact design—35 mm wide, 85 mm high, and 69 mm deep—facilitates easy integration into existing setups. With an IP20/IP40 degree of protection, it&#39;s well-suited for indoor installations while offering adequate defense against foreign objects and dust.</p><p>Engineered for durability, this RCBO supports up to 10,000 electrical cycles. Its short circuit capacity is rated at 10 kA with a residual current type F sensitivity of 30 mA to ensure effective earth fault protection. The C-curve characteristic allows it to handle moderate inrush currents typical in mixed load circuits without nuisance tripping.</p><p>Installation is straightforward thanks to the screw clamp terminal type that accommodates various cable cross sections: from solid core (0.75-25 sq-mm) to flexible wires with ferrules (0.75-16 sq-mm). The recommended tightening torque is set at 2.8 N-m for secure connections.</p><p>This device complies with IEC/EN standards (61009-1 &amp; -2-1), underscoring its adherence to international safety benchmarks. Rated insulation voltage reaches up to 500 V while the dielectric test voltage measures at an impressive 2 kV.</p><p>Operating efficiently within ambient temperatures ranging from -25&#176;C to +55&#176;C and supporting both busbar (10 sq-mm) and stranded wire connections (up to 25 sq-mm), flexibility in installation options is guaranteed. The power supply connection can be arbitrary due to its versatile design.</p><p>For added user convenience, contact position indication features red for ON and green for OFF states alongside a blue flag on the toggle indicating fault detection—a thoughtful touch that enhances operational clarity during maintenance or troubleshooting tasks.</p><p>Overall housing comes in RAL 7035 grey adding a professional finish compatible with most control panels or distribution boards mounted on DIN Rails under Overvoltage Category III conditions.</p><p>In summary, this RCBO offers comprehensive protection combined with ease of use—ideal attributes when seeking reliable solutions tailored towards complex electrical infrastructures across Australia’s industrial landscape.</p>
