<p>The S300P series MCB is a robust and reliable solution for those in the industrial and commercial sectors looking to safeguard their electrical systems. This miniature circuit breaker (MCB) offers a practical combination of safety features and technical specifications that cater to various applications.</p><p>Designed with precision, this MCB has a rated current of 8 A, making it suitable for moderate electrical loads. It operates effectively at rated voltages up to 415 VAC, ensuring compatibility with standard Australian electrical systems. The product&#39;s breaking capacity stands at an impressive 15 kA, providing substantial protection against short circuits.</p><p>Safety is further enhanced by its rated impulse withstand voltage of 6 kV and insulation voltage of 500 V. These attributes ensure durability even under high-stress conditions. The device meets several international standards including CSA 22.2 No. 235, IEC/EN 60898-1, IEC/EN 60947-2, and UL 1077, underscoring its reliability across diverse environments.</p><p>The MCB&#39;s design prioritizes user-friendliness and adaptability. It features a screw clamp terminal type with a tightening torque of 2.8 N-m for secure connections. Installation is straightforward on any DIN rail mounting system due to its compact dimensions—52.5 mm wide, 88 mm high, and 69 mm deep—and lightweight construction at just 0.372 kg.</p><p>Its operational resilience is evident from its ambient temperature range of -40 to +70 degrees Celsius and dielectric test voltage capacity of up to 2 kV. With an electrical durability rating of up to 20,000 cycles and short circuit capacity reaching up to an impressive peak of 25 kA under certain conditions, this MCB promises long-term dependability.</p><p>Additional features include an IP20/IP40 degree of protection depending on installation specifics which safeguards against dust ingress while maintaining easy access as needed during maintenance or inspections; it also boasts a degree of pollution rating at IP3 level suitable for typical indoor environments found in many industrial settings today.</p><p>This model supports arbitrary power supply connections allowing greater flexibility during setup while accommodating various system configurations without hassle or need for extensive modifications post-installation efforts are minimal thanks largely due not only these versatile connection options but also because wire stripping length requirements being set reasonably around fourteen millimeters (14mm).</p><p>Finally yet importantly housed within RAL7039 grey colored casing provides both aesthetic appeal alongside functional benefits such as reduced visibility dirt accumulation over time compared lighter colored counterparts might experience thus contributing overall cleaner appearance throughout lifecycle usage period too!</p>
