<p>The RCCB (Residual Current Circuit Breaker) is a critical component for ensuring electrical safety in both industrial and commercial environments. This device is designed to protect against earth fault currents, providing an essential layer of security by disconnecting the circuit when it detects imbalances that could indicate leakage or faults.</p><p>With a rated current of 40 A, this RCCB is suitable for moderate load applications. It operates efficiently across a rated voltage of 230 V and has been engineered to withstand impulse voltages up to 4 kV, making it robust enough for environments with transient overvoltages. The insulation voltage stands at 500 V, which ensures reliable performance under standard operational conditions.</p><p>This model features two poles and offers flexibility through a Type F residual current type, which is particularly adept at handling mixed frequencies and pulsed DC components commonly found in modern installations. Its instantaneous operating characteristic ensures rapid response to detected faults, minimizing potential hazards.</p><p>From a physical standpoint, the RCCB measures 35 mm in width, 85 mm in height, and 69 mm in depth while weighing just 225 g. These dimensions make it compact enough for space-constrained setups without compromising on functionality. Installation is straightforward with DIN rail mounting compatibility.</p><p>The device&#39;s terminals are equipped with screw clamps requiring a tightening torque of 2.8 N-m; these terminals support various cable cross-sections: from multi-wired cables ranging between 0-25 sq-mm to solid-core cables up to 25 sq-mm. The wire stripping length needed is only 12 mm, facilitating quick and efficient wiring during installation or maintenance tasks.</p><p>Rated for use within ambient temperatures from -25 to +55 degrees Celsius, this RCCB can endure diverse climatic conditions typical across Australia’s regions. It boasts an impressive electrical durability of up to 1000 cycles and can handle short-circuit currents as high as 10 kA—demonstrating its resilience under demanding circumstances.</p><p>In terms of protection levels, the unit provides IP20/IP40 degree protection depending on its installation environment—ensuring safety against foreign objects like fingers or tools when installed correctly within an enclosure offering additional protection if necessary.</p><p>Finally, the power supply connection allows arbitrary configuration enhancing versatility during integration into existing systems while maintaining optimal performance parameters throughout its lifecycle—a testament to its thoughtful engineering design aimed at delivering reliable safety solutions across varied applications.</p>
