<p>Introducing the S300P Series MCB, an industrial-grade miniature circuit breaker designed to meet the rigorous demands of commercial and industrial applications. This robust device offers a rated current of 40 A, making it suitable for various electrical circuits where dependable protection is crucial.</p><p>The S300P MCB is engineered with a rated voltage of 415 VAC and can withstand impulse voltages up to 6 kV, ensuring resilience against power surges. Its rated insulation voltage stands at 500 V, providing reliable isolation in diverse environments. With a breaking capacity of 15 kA and short circuit capacity reaching up to 20 kA, this MCB is well-suited for handling unexpected overloads efficiently.</p><p>This model features four poles and utilizes screw clamp terminals capable of handling a tightening torque of 2.8 N-m. The precise wire stripping length required is 14 mm, facilitating straightforward installation on any standard DIN rail mounting system. Its compact dimensions—70 mm in width, 88 mm in height, and 69 mm in depth—allow for easy integration into existing setups without compromising space efficiency.</p><p>The S300P&#39;s housing boasts a RAL 7039 Grey finish that not only provides aesthetic uniformity but also ensures durability under varying conditions. It operates effectively within ambient temperatures ranging from -40 to +70 degrees Celsius, demonstrating its adaptability across different climates.</p><p>Rated for both IP20 (finger-safe) and IP40 (when mounted in an enclosure), this MCB offers adequate protection against ingress of solid objects while maintaining optimal performance levels. Additionally, it adheres to several international standards such as CSA C22.2 No.235, IEC/EN 60898-1, IEC/EN 60947-2, and UL1077 certifications—testaments to its quality and reliability.</p><p>Electrical endurance is another highlight with the ability to perform up to 10,000 cycles before maintenance or replacement becomes necessary—a testament to its longevity in demanding operational settings.</p><p>Its curve type C characteristic makes it suitable for protecting general-purpose circuits where moderate start-up currents are expected without nuisance tripping during normal operations.</p><p>Furthermore, the S300P allows arbitrary power supply connection points along with flexible mounting positions enhancing versatility during installations or retrofits across varied applications ensuring seamless integration into your electrical systems setup whether it&#39;s new construction projects or upgrading existing infrastructures.</p>
