Description

<p>When it comes to ensuring the safety and reliability of your electrical installations, choosing the right Residual Current Circuit Breaker with Overcurrent protection (RCBO) is crucial. This RCBO offers a robust solution for industrial and commercial applications where precision and durability are paramount.</p><p>Rated at 50 A, this RCBO is designed to handle significant electrical loads with ease. Its rated voltage of 400/415 VAC, combined with a rated insulation voltage of 500 V, ensures that it can operate effectively in demanding environments. The device is built to withstand surges up to 4 kV, providing an additional layer of protection against transient overvoltages.</p><p>The RCBO features a short circuit capacity of 10 kA, making it suitable for circuits that experience high fault currents. With an electrical durability rating of 10,000 cycles, you can trust this device for long-term operation without frequent replacements. It complies with IEC standards (61009-1 and 61009-2-2) as well as AS/NZS 61009-1 standards, affirming its global quality recognition.</p><p>Installation flexibility is another highlight. The unit accommodates cable cross-sections ranging from solid-core cables (1-25 sq-mm) to multi-wired cables (1-16 sq-mm). Additionally, its connecting capacity supports busbars up to 10 sq-mm and flexible wires up to 16 sq-mm.</p><p>With dimensions measuring a width of 53.4 mm, height of 117.5 mm, and depth of 71.6 mm—alongside a weight of just over half a kilogram—this compact unit fits seamlessly into various panel setups without compromising space or performance.</p><p>Safety is further enhanced by the IP20 degree of protection which safeguards against accidental contact with live parts while maintaining operational integrity within ambient temperatures ranging from -5&amp;#176;C to +55&amp;#176;C. The Type A residual current detection provides reliable protection against earth faults involving both AC and pulsating DC components.</p><p>The RCBO operates on a C curve type characteristic which ensures instantaneous tripping during overload conditions—a critical feature for protecting sensitive equipment from damage due to unexpected power surges or faults.</p><p>For ease-of-use in diverse settings, the power supply connection is conveniently located at the bottom while the undelayed earthing switch type guarantees immediate response when needed most.</p><p>Overall, this RCBO combines technical excellence with practical functionality—making it an ideal choice for professionals seeking dependable circuit protection solutions in Australia’s rigorous industrial landscape.</p>
