Description

<p>When it comes to ensuring electrical safety and reliability in commercial and industrial settings, the S800S MCB stands out as a robust solution. This Miniature Circuit Breaker (MCB) is engineered for environments where durability and performance are paramount.</p><p>With a rated current of 20 A, this MCB efficiently manages electrical loads, making it suitable for various applications. It operates at a rated voltage of 400/690 VAC and boasts an impressive breaking capacity of 50 kA at 400 VAC, ensuring that it can handle significant fault conditions without compromising safety.</p><p>One of the key features is its high-rated impulse withstand voltage of 8 kV, which provides excellent protection against transient overvoltages commonly caused by lightning strikes or switching operations. The rated insulation voltage also stands strong at 690 V, offering reliable insulation under normal operating conditions.</p><p>The S800S MCB follows the C release type curve, ideal for protecting circuits with moderate inrush currents such as lighting or motor loads. Its electrical durability is noteworthy with up to 10,000 cycles, underscoring its long-term reliability in demanding environments.</p><p>Designed for convenience and ease of installation, this MCB uses screw clamp terminals with a tightening torque of 3.5 N-m. It accommodates cable cross-sections up to 50 sq-mm both on top and bottom connections, providing flexibility in wiring configurations.</p><p>Measuring at a width of 81 mm, height of 95 mm, and depth of 82.5 mm with each pole having a width of just 27 mm ensures that it fits neatly within standard DIN rail mounting systems – simplifying upgrades or replacements without needing extensive panel modifications.</p><p>The device’s degree of protection is IP20 while maintaining an operational temperature range from -25&amp;#176;C upwards – demonstrating resilience across various climatic conditions typical within Australian industries.</p><p>Compliance with standards IEC/EN 60947-2, IEC/EN 60898-1 alongside UL1077 affirms its adherence to international quality benchmarks ensuring peace-of-mind regarding product integrity during operation.</p><p>Finally housed in RAL7035 Grey color aligning aesthetically within control panels whilst supporting overvoltage category IV applications further broadens its deployment scope across diverse sectors facing challenging power quality scenarios daily.</p>
