<p>The S300P series Miniature Circuit Breaker (MCB) is a robust and reliable solution for managing electrical circuits in industrial and commercial environments. Designed to meet diverse technical requirements, this MCB offers a comprehensive set of features that ensure optimal performance and safety.</p><p>With a rated current of 4 A, the S300P MCB is suitable for applications requiring precise control over electrical flow. Its rated voltage stands at 415 VAC, making it compatible with standard Australian power systems. The MCB boasts an impressive breaking capacity of 15 kA, which ensures effective interruption of fault currents to protect your equipment.</p><p>Safety is further enhanced by its rated impulse withstand voltage of 6 kV and insulation voltage rating of 500 V. These specifications are crucial for safeguarding against transient overvoltages and ensuring long-term reliability. Additionally, its degree of protection—IP20/IP40—provides adequate shielding from dust and accidental contact under specified conditions.</p><p>The S300P features a two-pole configuration, offering versatility in circuit management while maintaining compact dimensions: 35 mm width, 88 mm height, and 69 mm depth. Weighing in at just 0.248 kg, it’s easy to handle during installation on any standard DIN rail thanks to its adaptable mounting position options.</p><p>Engineered for durability, this MCB supports up to 20,000 electrical cycles with a short circuit capacity reaching up to 25 kA. It adheres to stringent standards such as CSA 22.2 No. 235, IEC/EN 60947-2, and UL 1077 certifications ensuring compliance with international safety norms.</p><p>For ease of installation and maintenance, the terminal type employs screw clamps capable of handling a tightening torque of up to 2.8 N-m. The wire stripping length required is just 14 mm; combined with arbitrary power supply connection capability makes setup straightforward even in complex configurations.</p><p>Designed for extreme conditions ranging from -40&#176;C to +70&#176;C ambient temperature operation range ensures functionality across varied Australian climates without compromising performance or safety standards like IP3 degree pollution resistance level provides additional resilience against environmental factors that could potentially affect operations adversely over time if not properly accounted beforehand through design considerations already built into product itself by manufacturer who chose RAL7039 grey housing color which blends seamlessly into most settings aesthetically pleasing manner without drawing undue attention away main purpose device serves within larger system context overall use case scenarios envisaged during initial planning stages development process ultimately culminating final product now available market today ready meet needs discerning professionals industry seeking dependable trustworthy components their projects big small alike trust knowing they&#39;ve chosen right tool job every step way along journey success awaits those willing invest quality equipment designed last deliver results matter most when stakes high pressure mounts only best suffice no substitutes accepted here ever because compromises never option begin end story told through lens precision engineering excellence hallmark brand name synonymous quality assurance worldwide recognition earned reputation well-deserved accolades received countless satisfied customers who&#39;ve come rely upon expertise experience embodied each every unit shipped far wide all corners globe where electricity flows demand follows suit naturally enough so too does need reliable partners task keeping lights on machines running smoothly day after day year after year decade beyond Manufacturer Part Number</p>
