<p>When selecting a Miniature Circuit Breaker (MCB) for your industrial or commercial needs, it&#39;s crucial to focus on the specifications that ensure reliability and safety. The S300P series MCB is designed with these priorities in mind, offering robust performance across various applications.</p><p>This MCB boasts a rated current of 50 A and operates efficiently at a rated voltage of 415 VAC. It has an impressive breaking capacity of 15 kA, ensuring it can handle unexpected surges effectively. Safety is reinforced by its rated impulse withstand voltage of 6 kV and insulation voltage of 500 V, providing dependable protection against electrical faults.</p><p>The S300P series adheres to international standards such as CSA 22.2 No. 235, IEC/EN 60898-1, IEC/EN 60947-2, and UL 1077. These certifications affirm its quality and suitability for diverse environments. With an IP20/IP40 degree of protection, this MCB is safeguarded against solid foreign objects like fingers and provides limited protection against dust ingress.</p><p>Its physical dimensions include a width of 70 mm, height of 88 mm, and depth of 69 mm—compact enough for versatile installation while maintaining substantial operational integrity. Weighing just under half a kilogram at 0.496 kg makes it lightweight yet sturdy.</p><p>Designed for ease-of-use with screw clamp terminals requiring a tightening torque of 2.8 N-m ensures secure connections are maintained throughout its lifespan which includes an electrical durability rating capable of enduring up to ten thousand cycles.</p><p>Installation flexibility is another hallmark; the DIN rail mounting type allows for straightforward integration into existing setups without hassle regarding orientation due to its ability to be mounted in any position along with arbitrary power supply connection options enhancing adaptability further still.</p><p>For those operating within varied climate conditions from -40&#176;C up through +70&#176;C ambient temperatures rest assured knowing this unit remains reliable no matter what mother nature throws your way thanks largely due also perhaps partly attributable towards features like dielectric test voltages reaching values around two kilovolts alongside pollution degrees rated at IP3 levels respectively too!</p><p>Finally rounding off considerations would naturally involve housing aesthetics where you&#39;ll find standard RAL7039 grey hues present lending themselves well aesthetically speaking whether viewed individually or collectively amongst broader equipment arrays alike thus completing overall package quite nicely indeed all things considered here today now ultimately making informed decision easier than ever before when contemplating potential purchase moving forwards accordingly then hopefully soon thereafter!</p>
