<p>When selecting a Miniature Circuit Breaker (MCB) for industrial or commercial applications, the S800P series stands out as a robust choice. Designed to handle demanding electrical environments, this MCB offers reliability and efficiency.</p><p>First, let&#39;s focus on its electrical specifications. The MCB has a rated current of 80 A, making it suitable for high-demand circuits. It operates effectively at both 400 VAC and 690 VAC, providing flexibility across different voltage systems. With a rated impulse withstand voltage of 6 kV and an impressive breaking capacity of 50 kA, this device is engineered to safeguard against overcurrents and short circuits efficiently.</p><p>The physical dimensions are compact yet sturdy: with a width of 106 mm, height of 95 mm, and depth of 82.5 mm. Weighing in at just over one kilogram (1.005 kg), it’s manageable for installation while being robust enough for industrial use.</p><p>Its four-pole design ensures comprehensive protection across phases in three-phase systems or multiple single-phase circuits. With an IP20 degree of protection, the device is safeguarded against solid objects larger than 12mm but should be installed in enclosures where higher degrees of ingress protection are required.</p><p>Installation is straightforward thanks to its DIN rail mounting type, which simplifies setup and maintenance within electrical panels. The tightening torque specification stands at 3.5 N-m ensuring secure connections that can withstand operational vibrations.</p><p>To meet various wiring needs, the connecting capacity accommodates flexible wires from 1-50 sq-mm and rigid wires from 1-70 sq-mm with a wire stripping length requirement of only 19 mm—streamlining connection processes.</p><p>Operating under temperatures ranging from -25&#176;C to +60&#176;C highlights its versatility across diverse environmental conditions—a crucial factor for installations exposed to variable climates or indoor/outdoor settings.</p><p>The S800P series adheres to stringent standards such as IEC/EN 60947-2 and UL1077 ensuring compliance with international safety norms—an assurance vital for peace-of-mind regarding equipment safety and functionality.</p><p>This MCB features Curve Type D characteristics ideal for protecting circuits with high inrush currents such as transformers or motors by allowing temporary surges without tripping unnecessarily—a critical feature in many industrial setups.</p><p>For those concerned about energy efficiency amidst performance demands—the power loss registers at just around 25.4 W demonstrating an efficient balance between operational capability and energy consumption—vital considerations when managing large-scale operations&#39; electricity costs effectively.</p><p>Overall if you’re seeking an MCB that combines durability precision engineering compliance flexibility within rigorous technical parameters then look no further than this offering from the S800P series perfect fit your professional needs without compromise!</p>
