Description

<p>The S200M series MCB is a robust and reliable miniature circuit breaker designed for commercial and industrial applications. With a rated current of 20 A, it provides dependable protection for electrical circuits against overloads and short circuits. The S200M&amp;#39;s breaking capacity stands at an impressive 15 kA at 400 VAC, making it well-suited to handle high fault conditions.</p><p>This MCB operates efficiently within a rated voltage range of 400/415 VAC, ensuring compatibility with standard power systems. It boasts an impulse withstand voltage of 4 kV and an insulation voltage rated at 440 V, offering enhanced safety margins in fluctuating environments.</p><p>Designed with practicality in mind, the S200M features a screw clamp terminal type that supports cable cross sections up to 35 sq-mm on both top and bottom connections. The tightening torque requirement is set at 2.8 N-m, ensuring secure installation on DIN rails.</p><p>With dimensions of 52.5 mm width, 88 mm height, and a depth of 69 mm, this compact unit fits seamlessly into space-constrained setups while maintaining its robust performance capabilities. The housing comes in RAL 7035 grey—a neutral tone that blends well with most industrial equipment.</p><p>The S200M adheres to key standards such as AS/NZS 60898-1, AS/NZS 60947-2, and UL 1077 approvals—guaranteeing compliance with stringent safety regulations. Its electrical durability extends to an impressive lifespan of up to 20,000 cycles under normal operating conditions.</p><p>Engineered for versatility across different environments, the MCB can operate within ambient temperatures ranging from -25&amp;#176;C to +55&amp;#176;C and can be stored safely between -40&amp;#176;C to +70&amp;#176;C without compromising performance integrity. Its degree of protection is marked as IP20 while maintaining pollution degree IP3 standards—providing adequate protection against solid objects larger than fingers but not water ingress.</p><p>The product also includes curve type D characteristics which allow it to handle high inrush currents typically associated with inductive loads found in commercial settings like motors or transformers without unnecessary tripping incidents.</p><p>Overall power loss remains minimal at just about 2.3 W during operation—contributing positively towards energy efficiency considerations over long-term usage scenarios.</p><p>For installations requiring additional structural support or connectivity options beyond standard wiring practices; bulbar cross-sections are accommodated up until sizes reaching approximately ten square millimeters (top/bottom).</p><p>In summary: if you&amp;#39;re seeking dependable circuit protection solutions tailored specifically toward rigorous demands prevalent amongst Australian industries today—you&amp;#39;ll find everything necessary encapsulated inside each unit belonging proudly under our esteemed collection: Series S200M!</p>
