<p>The S300P series MCB is a robust and reliable choice for industrial and commercial applications, designed to meet rigorous standards while ensuring optimal performance. With a rated current of 40 A, this miniature circuit breaker is well-suited for protecting electrical circuits from overloads and short circuits.</p><p>This device operates at a rated voltage of 415 VAC with an impressive breaking capacity of 15 kA, ensuring it can handle significant fault conditions. The dual-pole configuration provides enhanced safety by isolating both live conductors in the event of a fault. Its rated impulse withstand voltage stands at 6 kV, offering excellent protection against transient overvoltages commonly caused by lightning strikes or switching surges.</p><p>Engineered with user convenience in mind, the MCB features screw clamp terminals that support secure connections. The tightening torque requirement is set at 2.8 N-m to ensure stable contact without damaging wires. It accommodates a wire stripping length of 14 mm for easy installation.</p><p>The compact dimensions—35 mm width, 88 mm height, and 69 mm depth—make it suitable for integration into various control panels without consuming excessive space. Despite its size, it maintains durability with an electrical lifespan of up to 10,000 cycles and can operate within ambient temperatures ranging from -40 to 70 degrees Celsius.</p><p>Safety compliance is assured as it meets several international standards such as CSA C22.2 No. 235, IEC/EN 60898-1, IEC/EN 60947-2, and UL 1077 certifications. Its degree of protection varies between IP20/IP40 depending on the enclosure used; this ensures adequate protection against dust ingress and accidental contact with live parts.</p><p>Designed for versatility in mounting options, this MCB can be installed on any standard DIN rail in any orientation thanks to its arbitrary power supply connection capability and flexible mounting position requirements.</p><p>Featuring a curve type C characteristic means it&#39;s ideal for applications where moderate levels of inrush currents are expected like motor start-ups or capacitive loads while maintaining effective short-circuit protection.</p><p>The housing comes in RAL 7039 grey which blends seamlessly into most industrial environments providing both aesthetic appeal and functional reliability whilst weighing just under a quarter kilogram (0.248 kg).</p><p>Withstanding dielectric test voltages up to 2 kV further attests its resilience under high-stress conditions making it an asset across varied operational settings including those subjected frequently fluctuating environmental factors given its degree pollution rating at IP3 level allowing use even adverse circumstances encountered regularly within Australian contexts especially considering common weather extremes experienced locally year-round thus ensuring continued service delivery uninterruptedly regardless situational challenges faced consistently throughout lifecycle usage demands anticipated accordingly overall performance expectations met satisfactorily all considered ultimately concluding suitability assessment conducted thoroughly beforehand confidently justified decision-making processes undertaken successfully thereafter ultimately confirming appropriateness selection criteria fulfilled entirely Manufacturer Part Number: S300P</p>
