<p>When selecting a Miniature Circuit Breaker (MCB) for commercial or industrial applications, it&#39;s essential to consider both performance and compliance with Australian standards. The S800N series MCB offers robust features that cater to demanding electrical environments, ensuring safety and reliability.</p><p>This MCB is designed for use in both single-phase and three-phase systems with its rated voltage of 230/400 VAC. It supports a rated current of 63 A, making it suitable for various heavy-duty applications. With a breaking capacity of 36 kA at 230 VAC, this breaker can handle significant fault currents without compromising system integrity.</p><p>The product&#39;s impulse withstand voltage is rated at an impressive 8 kV, providing excellent protection against transient overvoltages typically caused by lightning strikes or switching surges. Additionally, the MCB boasts a rated insulation voltage of 690 V, offering enhanced safety margins in high-voltage scenarios.</p><p>Constructed with durability in mind, the unit has an electrical endurance of up to 6000 cycles. This ensures long-term performance even under frequent operational conditions. Its short circuit capacity stands at 25 kA which complements its main breaking capacity feature.</p><p>For ease of installation and maintenance, the MCB utilizes screw clamp terminals requiring a tightening torque of 3.5 N-m and accommodates cable cross-sections up to 50 sq-mm on both top and bottom connections. The device&#39;s design allows for quick mounting on standard DIN Rails.</p><p>With dimensions measuring 27 mm in width, 95 mm in height, and a depth of 82.5 mm, this compact unit fits seamlessly into existing panels without occupying excessive space. The housing is finished in RAL 7035 grey—an industry-standard color that blends well within most control cabinets.</p><p>Safety certifications are vital; thus this MCB complies with AS/NZS standards such as AS/NZS 60898-1 and AS/NZS 60947-2 ensuring adherence to local regulations. The IP20 degree of protection indicates suitability for indoor installations where exposure to dust or moisture is minimal while maintaining user safety from accidental contact with live parts.</p><p>Its Curve Type C characteristic makes it ideal for applications involving moderate inductive loads like motors or transformers where higher inrush currents are expected upon startup but require rapid disconnection during faults beyond normal operating parameters.</p><p>In summary—the S800N series provides reliable protection tailored specifically towards rigorous commercial &amp; industrial settings—offering peace-of-mind through proven technical specifications supported by regional standard compliance—all encapsulated within a durable yet compact form factor perfecting balance between functionality &amp; practicality without sacrificing quality nor efficiency throughout its lifecycle.</p>
