<p>For those in the industrial and commercial sectors seeking a reliable and robust Miniature Circuit Breaker (MCB), this model from the S300P series offers a blend of performance and durability. Designed to meet various technical requirements, it stands out with its comprehensive specifications tailored for demanding environments.</p><p>Rated at 20 A, this MCB is built to handle significant electrical loads, making it suitable for diverse applications. Its rated impulse withstand voltage of 6 kV ensures resilience against transient overvoltages, while the rated insulation voltage of 500 V provides an added layer of safety. Operating effectively at a rated voltage of 415 VAC, it&#39;s equipped to manage standard industrial power systems.</p><p>One notable feature is its breaking capacity of 15 kA, ensuring that it can safely interrupt high fault currents without damage. The short circuit capacity extends up to 25 kA, further highlighting its capability in handling extreme conditions. With an electrical durability rating of 20000 cycles, users can expect long-term reliability.</p><p>The MCB&#39;s design incorporates four poles and adheres to rigorous standards such as CSA 22.2 No. 235, IEC/EN 60898-1, IEC/EN 60947-2, and UL 1077 approvals—demonstrating compliance with international safety norms. Its degree of protection ranges from IP20/IP40 depending on installation specifics.</p><p>Installation is straightforward with a screw clamp terminal type requiring a tightening torque of 2.8 N-m and accommodating wire stripping lengths up to 14 mm. The device mounts onto DIN rails effortlessly and supports arbitrary power supply connections in any mounting position—offering flexibility during setup.</p><p>Physically compact yet sturdy with dimensions measuring a width of 70 mm by height of 88 mm by depth of 69 mm; it weighs in at just under half a kilogram (0.496 kg). This makes it manageable within control panels where space might be limited but performance cannot be compromised.</p><p>For operational environments ranging from -40&#176;C to +70&#176;C ambient temperature conditions are well within its operating range; thus catering not only for typical but also more extreme climates found across Australia’s varied landscape.</p><p>The unit features K curve characteristics ideal for protecting circuits with inductive loads like motors or transformers—commonplace across many industries today—and has been designed using RAL7039 grey housing which blends seamlessly into most equipment settings aesthetically speaking whilst maintaining functional integrity throughout usage lifespan thanks largely due dielectric test voltage rating set at two kilovolts alongside pollution degree classification marked as IP3 level assurance against environmental contaminants ingress potentially affecting internal components adversely over time if unchecked otherwise left exposed unnecessarily so instead here safeguarded accordingly via thoughtful engineering considerations applied practically wherever possible overall inherently built-in advantageously seen throughout entire product lifecycle ultimately benefiting end-users directly firsthand reliably consistently dependably always assuredly undoubtedly confidently!</p>
