<p>The S300P series MCB is a robust and reliable choice for industrial and commercial applications, designed to meet the demanding needs of the Australian market. With a rated current of 40 A, this miniature circuit breaker (MCB) ensures efficient protection against overloads and short circuits.</p><p>One of its notable features is the rated impulse withstand voltage of 6 kV, which provides resilience against transient overvoltages. The device operates at a rated insulation voltage of 500 V and supports a rated voltage up to 415 VAC, making it suitable for various electrical systems.</p><p>The S300P MCB boasts an impressive breaking capacity of 15 kA, ensuring that it can handle high fault currents effectively. It also offers dual degree protection with IP20/IP40 ratings, safeguarding internal components from dust and accidental contact.</p><p>Installation is straightforward with its screw clamp terminal type, requiring a tightening torque of 2.8 N-m for secure connections. The compact dimensions—35 mm width, 88 mm height, and 69 mm depth—allow for easy integration into existing setups without compromising on space efficiency.</p><p>For those concerned about standards compliance, this MCB aligns with CSA 22.2 No. 235, IEC/EN 60898-1, IEC/EN 60947-2, and UL 1077 certifications. This adherence guarantees reliability under varied operational conditions.</p><p>With an electrical durability rating of up to 10,000 cycles and a short circuit capacity reaching up to an impressive 20 kA under certain conditions (notably higher than its standard breaking capacity), this unit promises longevity in performance.</p><p>Engineered for versatility in installation environments—from harsh cold (-40&#176;C) to intense heat (70&#176;C)—it maintains functionality across diverse ambient temperatures. Its dielectric test voltage stands at a solid 2 kV.</p><p>The product’s design allows mounting on DIN rails in any position with arbitrary power supply connection orientation—enhancing flexibility during setup phases. For ease during wiring tasks, it accommodates wire stripping lengths up to 14 mm efficiently while maintaining structural integrity through its RAL7039 grey housing color which blends well within most industrial settings.</p><p>In summary: If you’re seeking dependable performance wrapped in durable construction backed by global standards compliance—the S300P series should be your go-to solution when specifying requirements align closely with these parameters without sacrificing quality or safety benchmarks expected within professional spheres today!</p>
