Description

<p>The S200M MCB is a reliable choice for those in commercial and industrial sectors seeking robust circuit protection. With a rated current of 4 A, this miniature circuit breaker (MCB) is engineered to handle demanding electrical environments. It boasts a rated voltage of 400/415 VAC, making it suitable for various applications across Australia.</p><p>One of the standout features is its impressive breaking capacity of 15 kA at 400 VAC, ensuring safety and reliability in fault conditions. The S200M series adheres to rigorous standards such as AS/NZS 60898-1, AS/NZS 60947-2, and UL 1077, underscoring its quality and compliance with international safety norms.</p><p>Designed with practicality in mind, this MCB has a compact form factor with dimensions of 52.5 mm width, 88 mm height, and 69 mm depth. Its three-pole configuration offers enhanced flexibility for different installation scenarios. The device fits seamlessly onto DIN rails—a common mounting type—allowing easy integration into existing systems.</p><p>Electrical durability is another key attribute; the S200M can endure up to 20,000 operational cycles, ensuring longevity even under frequent switching conditions. It operates efficiently within ambient temperatures ranging from -25&amp;#176;C to +55&amp;#176;C and can be stored safely between -40&amp;#176;C and +70&amp;#176;C.</p><p>The product&amp;#39;s degree of protection stands at IP20 while offering an IP3 pollution degree rating—suitable for indoor use where dust or water ingress isn&amp;#39;t a major concern. The terminal type features screw clamps designed to accommodate cable cross-sections up to 35 sq-mm on both top and bottom connections.</p><p>For professionals prioritizing precision during installation, the recommended tightening torque is set at 2.8 N-m. This ensures secure connections that maintain system integrity over time.</p><p>Power loss remains minimal at just 1.7 W which contributes positively towards energy efficiency goals within your setup. Furthermore, the curve type D characteristic allows it to manage high inrush currents often found in inductive loads like motors or transformers without nuisance tripping.</p><p>With housing colored RAL 7035 grey—a neutral tone that blends well into most control panels—the S200M maintains an understated yet professional appearance suited for any technical environment.</p><p>In summary, whether you&amp;#39;re upgrading an existing infrastructure or setting up new installations requiring dependable circuit protection solutions compliant with Australian standards—the S200M series offers solid performance backed by proven engineering credentials tailored specifically for commercial and industrial applications.</p>
