<p>When selecting a Miniature Circuit Breaker (MCB) for industrial and commercial applications, understanding the technical specifications is crucial. This MCB from the S300P series offers robust performance with a rated current of 4 A, making it suitable for various electrical systems. It operates efficiently within a wide ambient temperature range of -40 to 70 degrees Celsius, ensuring reliability in diverse environments.</p><p>With a rated impulse withstand voltage of 6 kV and an insulation voltage of 500 V, this MCB is designed to handle high-voltage conditions safely. The rated voltage stands at 415 VAC, supporting standard industrial power systems. An impressive breaking capacity of 15 kA ensures that it can effectively interrupt fault currents without compromising safety or performance.</p><p>The device features three poles and adheres to IP20/IP40 protection standards, providing adequate protection against solid objects and limited ingress of water. For secure connections, it employs screw clamp terminals with a tightening torque of 2.8 N-m and has been engineered for easy installation on DIN rails with arbitrary power supply connection orientations.</p><p>Measuring at a width of 52.5 mm, height of 88 mm, and depth of 69 mm, this compact unit fits seamlessly into existing setups without requiring significant space adjustments. Despite its small size, the MCB does not compromise on durability or performance; it boasts an electrical durability rating capable of handling up to 20000 cycles.</p><p>Conforming to CSA 22.2 No. 235, IEC/EN standards such as IEC/EN 60898-1 and IEC/EN60947-2 as well as UL1077 approvals ensures compliance with international safety regulations—offering peace of mind regarding quality assurance.</p><p>Weighing only about 0.372 kg makes handling straightforward during installation or maintenance processes while maintaining stability once mounted due largely thanks due partly due largely thanks due partly due largely thanks in part by its sturdy construction featuring RAL7039 grey housing which blends well aesthetically within most installations settings</p><p>This model supports both IP3 pollution degree ratings along with C curve type characteristics suited ideally towards protecting circuits against overloads short-circuits alike especially those involving inductive loads such motors transformers etc., allowing users greater flexibility when integrating into complex systems where precision control over current flow essential</p><p>Overall whether upgrading existing infrastructure building new projects from scratch opting choosing reliable components like these means investing long-term operational efficiency reduced downtime ultimately leading cost savings improved productivity Manufacturer Part Number: S300P</p>
