<p>When it comes to selecting the right Miniature Circuit Breaker (MCB) for your project, understanding its technical specifications is crucial. The S300P series MCB offers a reliable solution designed to meet industrial and commercial needs with precision.</p><p>This MCB has a rated current of 4 A, making it suitable for various low-current applications. Its rated impulse withstand voltage stands at 6 kV, ensuring robust protection against transient overvoltages typically caused by lightning strikes or switching surges. With a rated insulation voltage of 500 V and a rated operational voltage of 240 VAC, this device is well-suited for standard electrical systems.</p><p>One of the standout features is its high breaking capacity of 15 kA. This makes it capable of safely interrupting significant fault currents without damage, providing peace of mind in demanding environments. The degree of protection ranges from IP20 to IP40 depending on installation conditions, offering adequate safeguarding against solid objects and limited moisture ingress.</p><p>The MCB&#39;s physical dimensions are compact with a width of 17.5 mm, height of 88 mm, and depth measuring at 67.6 mm—ideal for space-constrained installations on DIN rails. It supports easy integration into existing setups thanks to its screw clamp terminal type that requires a tightening torque of 2.8 N-m.</p><p>Compliant with standards such as CSA 22.2 No. 235, IEC/EN 60947-2, and UL 1077, this circuit breaker meets stringent safety requirements globally recognized across the industry.</p><p>Its electrical durability is impressive at up to 20,000 cycles which ensures longevity even under frequent operation scenarios—perfect for dynamic work environments where reliability is non-negotiable.</p><p>With an operating ambient temperature range from -40 to +70 degrees Celsius and arbitrary power supply connection orientation; flexibility in varied climates or orientations won’t be an issue here either! The housing colour RAL7039 Grey gives it an understated yet professional appearance.</p><p>For those concerned about pollution levels affecting performance: rest assured knowing there’s only minimal impact due largely because our product holds an IP3 degree rating!</p><p>Finally addressing convenience during setup—the wire stripping length required sits comfortably around fourteen millimeters while mounting positions remain versatile enough so you can place them wherever necessary within your system’s framework quickly efficiently every time!</p><p>In conclusion if you’re seeking dependable functionality combined seamlessly alongside ease-of-use then look no further than what we offer today through these exceptional features found exclusively within our trusted line-up known affectionately by many simply as Series S300P!</p>
