Description

<p>When selecting a reliable Miniature Circuit Breaker (MCB) for commercial or industrial applications, the S200M Series offers an impressive balance of performance and durability. With its robust design, this MCB is well-suited to handle demanding environments.</p><p>The S200M MCB operates with a rated current of 25 A, ensuring it can manage moderate electrical loads efficiently. It features a rated impulse withstand voltage of 4 kV and an insulation voltage of 440 V, providing ample protection against electrical surges. This breaker supports a rated operational voltage range between 400/415 VAC, making it versatile for various power systems.</p><p>A key feature is its breaking capacity of 15 kA at 400 VAC, which ensures effective interruption in the event of overloads or short circuits. The device&amp;#39;s electrical durability is notable with up to 20,000 cycles, promising longevity and reliability in continuous use.</p><p>The S200M MCB adheres to stringent standards including AS/NZS 60898-1 and AS/NZS 60947-2 as well as UL 1077 certification. These approvals underscore its compliance with safety regulations and international quality benchmarks.</p><p>In terms of physical specifications, this three-pole unit measures at a width of 52.5 mm, height of 88 mm, and depth of 69 mm. Its compact size allows for efficient space utilization within control panels while the RAL 7035 grey housing provides a professional appearance that blends seamlessly into most installations.</p><p>For ease of installation, the MCB uses screw clamp terminals with a tightening torque specification of 2.8 N-m. It accommodates cable cross sections up to 35 sq-mm on both top and bottom connections along with bulbar cross sections up to10 sq-mm each side.</p><p>Rated for operation across ambient temperatures from -25&amp;#176;C to +55&amp;#176;C—and storage conditions as low as -40&amp;#176;C—the S200M series proves adaptable under varying environmental conditions without compromising performance integrity.</p><p>This model boasts IP20 degree protection against solid objects larger than12mm ensuring basic safety in handling during maintenance activities while offering pollution degree3 resistance suitable for industrial settings prone to dust exposure or similar contaminants</p><p>With curve type D characteristics designed specifically targeting applications involving high inrush currents like motors transformers etc., users can trust consistent tripping response tailored precisely towards their unique requirements</p><p>Finally mounting onto standard DIN rails simplifies integration alongside existing equipment setups whether upgrading current systems expanding new installations alike Manufacturer Part Number: [Not Applicable]</p>
