<p>When selecting a Molded Case Circuit Breaker (MCCB) for your industrial or commercial applications, understanding the technical specifications is crucial. This MCCB is designed to meet rigorous demands with its robust set of features and compliance with international standards.</p><p>With a rated current of 125 A, this MCCB efficiently handles substantial electrical loads. It supports both AC and DC systems, with rated voltages of 690 VAC and 500 VDC respectively, making it versatile for different power setups. The rated insulation voltage stands at an impressive 800 V, ensuring safety and reliability under various conditions.</p><p>A notable feature is its high breaking capacity of 50 kA, which provides excellent protection against short circuits by interrupting excessive currents swiftly. The device also boasts a rated impulse withstand voltage of 8 kV, safeguarding against transient overvoltages typically caused by lightning strikes or switching surges.</p><p>The trip unit type TMD (Thermal Magnetic Device) ensures precise operation under overload conditions while the TM release type enhances response time during fault occurrences. Users can adjust the current setting range between 87.5 to 125 A to suit specific circuit requirements.</p><p>This MCCB comes equipped with four poles and connects via front bolt terminals, supporting main circuit connecting capacities ranging from 85 to 192 sq-mm. Its compact design features a width of just 140 mm, facilitating easy integration into existing panels without requiring extensive space adjustments.</p><p>Rated for frequencies between 50/60 Hz, it aligns well with standard electrical systems globally. Power loss is minimized at only 6.6 W, contributing to energy efficiency in your installations.</p><p>In terms of protection levels, it carries an IP20 rating which offers basic protection against solid objects larger than 12 mm but should be installed in appropriate enclosures for added environmental security if necessary.</p><p>Weighing in at only 2.1 kg makes handling straightforward during installation or maintenance tasks. Furthermore, this MCCB complies with IEC60947-2 standards and approvals ensuring you are investing in a product that meets essential quality benchmarks recognized worldwide.</p><p>Lastly, it&#39;s compatible for use alongside XT3S series components providing flexibility if you&#39;re integrating into pre-existing systems or planning expansions down the line.</p>
