<p>When selecting a Miniature Circuit Breaker (MCB) for industrial and commercial applications, understanding the technical specifications is crucial to ensure it meets your operational needs. The S300P series MCB offers reliable performance with a focus on safety and durability, making it a solid choice for professionals in the electrical engineering field.</p><p>This MCB is rated for a current of 4 A and can handle impulse voltages up to 6 kV. It operates effectively at an insulation voltage of 500 V and has a rated voltage capacity of 415 VAC. With power loss maintained at just 5.6 W, this device ensures efficient energy use while minimizing heat generation.</p><p>Designed with four poles, this breaker boasts a breaking capacity of 15 kA, along with an impressive short circuit capacity of 25 kA. These features make it suitable for environments where high fault currents are expected. Additionally, its degree of protection ranges from IP20 to IP40, providing adequate safeguarding against dust and accidental contact.</p><p>The terminal type employs screw clamps that require a tightening torque of 2.8 N-m for secure connections. Its dimensions—70 mm in width, 88 mm in height, and 69 mm in depth—allow easy integration into various panel designs without occupying excessive space.</p><p>Conforming to international standards such as CSA 22.2 No. 235, IEC/EN 60898-1, IEC/EN 60947-2, and UL 1077 ensures compliance with global safety requirements. Weighing just under half a kilogram at 0.496 kg enhances its suitability for installations where weight considerations are important.</p><p>Operating within frequencies ranging from 50 to 60 Hz and capable of enduring up to an impressive electrical durability of over twenty thousand cycles highlights its robustness over time.</p><p>With pollution degree classified as IP3 and featuring C curve tripping characteristics, it&#39;s designed to handle moderate overloads efficiently without unnecessary tripping during normal operation peaks.</p><p>Installation flexibility is another key advantage; it&#39;s compatible with standard DIN rail mounting systems allowing easy setup across different configurations due to its arbitrary power supply connection capability which supports any mounting position necessary within your design constraints.</p><p>For ease during installation or maintenance tasks like wire connections or replacements—the recommended wire stripping length is set at precisely fourteen millimeters ensuring optimal contact surface area every time you work on it!</p><p>Finally covering ambient temperatures ranging from -40&#176;C up through +70&#176;C means this unit performs reliably even under extreme conditions typical inside industrial settings whether they’re located outdoors exposed directly sunlight elements indoors subject fluctuating climate controls alike thanks largely protective RAL7039 grey housing color offering both aesthetic appeal practicality needed endure rigors daily usage!</p>
