Description

<p>When it comes to selecting a reliable Miniature Circuit Breaker (MCB) for your commercial or industrial needs, the S800N series offers a robust solution. Designed with precision and compliance in mind, this MCB is suitable for environments where safety and efficiency are paramount.</p><p>The MCB operates at a rated current of 50 A, ensuring that it can handle significant electrical loads without faltering. It is engineered to withstand an impressive impulse voltage of 8 kV and has a rated insulation voltage of 690 V. This makes it well-suited for demanding applications that require high levels of durability and reliability.</p><p>One of the standout features of this MCB is its breaking capacity. At 400 VAC, it boasts a breaking capacity of 36 kA, providing substantial protection against short circuits and overloads. The device&amp;#39;s short circuit capacity stands at 25 kA, further emphasizing its capability to manage unexpected electrical surges effectively.</p><p>The S800N series adheres to stringent standards such as AS/NZS 60898-1 and AS/NZS 60947-2, ensuring compliance with Australian safety regulations. The degree of protection offered by this MCB is IP20, making it suitable for installation in controlled environments where protection from solid objects larger than 12 mm is required.</p><p>Installation flexibility is ensured with the DIN rail mounting type. The screw clamp terminal type supports secure connections with a tightening torque specification of 3.5 N-m. Accommodating cable cross-sections up to 50 sq-mm on both top and bottom terminals allows for versatile wiring configurations.</p><p>In terms of dimensions, the MCB measures at a width of 81 mm, height of 95 mm, and depth of 82.5 mm—compact yet sturdy enough for various installation setups. Its pole width sits at an efficient 27 mm per pole across three poles.</p><p>Durability extends beyond physical construction; electrically speaking, the device guarantees longevity with an electrical durability rating reaching up to 6000 cycles under normal conditions—a testament to its resilience over extended periods.</p><p>Operating within ambient temperatures ranging from -25&amp;#176;C to +60&amp;#176;C ensures adaptability in diverse climate conditions while storage capabilities extend from -40&amp;#176;C up to +70&amp;#176;C without compromising integrity.</p><p>With a housing colour coded RAL7035 grey—a subtle yet professional finish—the S800N blends seamlessly into any industrial or commercial setting while maintaining functional aesthetics.</p><p>This product serves both commercial and industrial applications efficiently through its Curve Type C characteristic which provides adequate response times during fault conditions typical in these settings.</p>
