<p>The S300P Series Miniature Circuit Breaker (MCB) is designed to meet the demanding requirements of industrial and commercial applications. With a rated current of 20 A, this MCB is well-suited for protecting electrical circuits from overloads and short circuits, ensuring safety and reliability in your installations.</p><p>Engineered to handle a rated voltage of 415 VAC and a breaking capacity of 15 kA, the S300P provides robust protection against electrical faults. The device&#39;s ability to withstand impulse voltages up to 6 kV adds an extra layer of resilience, making it suitable for environments prone to power surges or lightning strikes.</p><p>This MCB features four poles, offering comprehensive coverage for multi-phase systems. Its compact dimensions—70 mm in width, 88 mm in height, and 69 mm in depth—facilitate easy integration into existing setups without compromising on space efficiency. The housing is finished in RAL 7039 grey, providing a neutral aesthetic that blends seamlessly with other equipment.</p><p>Installation flexibility is another highlight of the S300P. It mounts effortlessly onto DIN rails and accommodates any mounting position thanks to its arbitrary power supply connection design. The screw clamp terminal type supports secure connections with a tightening torque of 2.8 N-m while allowing for wire stripping lengths up to 14 mm.</p><p>The degree of protection ranges from IP20 when installed within an enclosure to IP40 when standalone components are considered—a testament to its versatility across different environments. Furthermore, it meets stringent standards such as CSA 22.2 No. 235, IEC/EN 60898-1, IEC/EN 60947-2, and UL 1077 certifications.</p><p>From an operational standpoint, the S300P can function effectively across temperatures ranging from -40&#176;C to +70&#176;C while maintaining electrical durability over approximately 20,000 cycles at frequencies between 50/60 Hz. This makes it reliable even under extreme conditions or frequent use scenarios.</p><p>With a dielectric test voltage rating of up to 2 kV and supporting pollution degree IP3 environments, this MCB ensures continued performance even amidst challenging conditions typical in industrial settings.</p><p>Whether you&#39;re upgrading existing systems or implementing new ones within buildings or factories across Australia’s diverse climate zones—the S300P Series MCB stands out as a dependable choice aligning perfectly with technical expectations without unnecessary complexities or frills often associated with similar products on the market today.</p>
