<p>When it comes to selecting a reliable and efficient Molded Case Circuit Breaker (MCCB) for industrial and commercial applications, this product stands out with its robust specifications. Designed to meet the demanding needs of electrical systems, it offers a blend of performance and safety.</p><p>With a rated current of 50 A, this MCCB is well-suited for medium-scale electrical installations. The device operates efficiently within a voltage range of 690/750 VAC/VDC, providing flexibility in various environments. Its rated insulation voltage of 1000 V ensures that it can handle high-voltage systems with ease, while the rated impulse withstand voltage of 8 kV adds an extra layer of protection against transient overvoltages.</p><p>Safety is further enhanced by its breaking capacity of 36 kA, which ensures effective interruption under fault conditions. The MCCB&#39;s trip unit is TMA type—a thermal-magnetic release mechanism—offering dependable protection by automatically disconnecting circuits during overloads or short circuits.</p><p>This model features four poles and utilizes front connection types with bolt terminals for secure installation. The IP20 degree of protection indicates that the device is protected against solid objects larger than 12 mm but does not offer water protection; therefore, it&#39;s best suited for indoor use where moisture exposure is minimal.</p><p>The MCCB’s width measures at a compact 140 mm, making it space-efficient without compromising on functionality. It weighs in at 3.5 kg, striking a balance between sturdiness and manageability during installation.</p><p>Compliance with IEC60947-2 standards underscores its adherence to globally recognized safety and performance benchmarks—an assurance appreciated by professionals who prioritize quality compliance in their projects.</p><p>For those concerned about energy efficiency, this MCCB has a power loss rating of just 4.68 W when operating at full load conditions—a feature that contributes to reduced operational costs over time.</p><p>Operating effectively across frequencies ranging from 50 to 60 Hz makes this breaker suitable for both domestic and international applications where varying grid frequencies may be encountered.</p><p>Its main circuit connecting capacity accommodates conductors ranging from 85-200 sq-mm, allowing integration into diverse wiring setups typical in complex installations. Furthermore, the current setting range between 35-50 A offers adaptability based on specific load requirements.</p><p>Engineered as compatible with XT4N devices enhances its versatility within existing systems equipped with these components—making upgrades or replacements straightforward without extensive modifications required.</p><p>Overall, this MCCB combines durability with advanced protective features tailored for professional settings where reliability cannot be compromised.</p>
