<p>When it comes to selecting a reliable and efficient Molded Case Circuit Breaker (MCCB) for industrial or commercial applications, understanding the specifications is crucial. This MCCB offers a comprehensive suite of features tailored to meet demanding electrical requirements.</p><p>Starting with its rated current, this MCCB supports up to 125 A, making it suitable for various medium-load applications. It boasts a robust rated impulse withstand voltage of 8 kV and an impressive rated insulation voltage of 800 V. These characteristics ensure that the device can handle unexpected surges effectively while maintaining safety.</p><p>The MCCB operates efficiently across both AC and DC systems, with a rated voltage capacity of 690 VAC and 500 VDC. This versatility is further enhanced by its release type—Thermal Magnetic (TM)—and trip unit configuration, Thermal Magnetic Discriminator (TMD), which provide precise protection against overloads and short circuits.</p><p>With power loss minimized to just 10.7 W, this breaker ensures energy efficiency without compromising performance. The four-pole design caters to varied connection needs while maintaining stability during operation.</p><p>A critical aspect of any circuit breaker is its breaking capacity; at 50 kA, this MCCB can safely interrupt significant fault currents without damage. It uses front connections with bolt terminals for secure installation in panels or enclosures.</p><p>Rated at IP20 for degree of protection, this breaker is designed primarily for indoor use where dust ingress protection is necessary but moisture exposure is minimal. Its compact width of 101.6 mm allows for space-efficient installations within distribution boards or control panels.</p><p>Compliance with IEC60947-2 standards guarantees adherence to international safety and performance benchmarks—a vital consideration when integrating components into existing systems. Weighing only 1.4 kg makes handling straightforward during installation or maintenance procedures.</p><p>Operating seamlessly on both standard frequencies—50 Hz and 60 Hz—this MCCB adapts well across different regions&#39; electrical infrastructures. It’s compatible with XT1S devices, ensuring flexibility in system design choices.</p><p>For those concerned about short-circuit scenarios, the device&#39;s rated short circuit current stands at an impressive 1250 A offering substantial resilience under extreme conditions while providing adjustable current settings ranging from 87.5 A to the full-rated capacity of 125 A allowing fine-tuning based on specific application demands.</p><p>Finally, accommodating main circuit connecting capacities between 45.5 sq-mm and 80 sq-mm ensures compatibility with various wiring sizes facilitating ease-of-integration into existing setups without requiring extensive modifications.</p>
