<p>When it comes to selecting a reliable and robust Molded Case Circuit Breaker (MCCB) for your industrial or commercial setup, the specifications of this product offer a compelling choice for professionals seeking performance and dependability. Designed to meet rigorous standards, this MCCB is tailored for those who prioritize precise technical details in their electrical systems.</p><p>This MCCB boasts a rated current of 40 A and can handle both AC and DC applications with its rated voltage capacity of 690/750 VAC/VDC. Its impressive rated impulse withstand voltage of 8 kV ensures resilience against transient overvoltages, making it suitable for demanding environments. The device&#39;s rated insulation voltage stands at 1000 V, adding an extra layer of safety to your electrical infrastructure.</p><p>The trip unit type is TMA (Thermal Magnetic Adjustable), providing flexibility in operation with a current setting range between 28-40 A. This allows users to tailor the protection settings according to specific load requirements, enhancing both safety and efficiency. With a breaking capacity of 50 kA, this MCCB is designed to interrupt fault currents effectively, safeguarding equipment from potential damage.</p><p>Engineered with four poles and featuring front connection type, installation becomes straightforward while maintaining accessibility for maintenance operations. The bolt terminal type further simplifies secure connections within the system. Its width measures at 140 mm, ensuring that it can fit into various panel configurations without hassle.</p><p>Certified under IEC60947-2 standards, this MCCB meets international quality benchmarks ensuring reliability across diverse applications. Its degree of protection is IP20 which provides basic protection against solid objects larger than 12mm like fingers or similar objects but does not protect against water ingress – something important to consider depending on the environment where it&#39;s installed.</p><p>With power loss limited to just 4.49 W during operation and weighing only 3.5 kg, this breaker strikes a balance between energy efficiency and ease of handling during installation or replacement tasks.</p><p>Compatible specifically with XT4S units, it offers versatility in integration within existing systems while supporting main circuit connecting capacities ranging from 85-200 sq-mm cable sizes - accommodating varied wiring needs efficiently.</p><p>Finally yet importantly operating smoothly across frequencies ranging from 50/60 Hz makes sure that no matter what local power grid conditions are present compatibility issues won&#39;t arise allowing seamless incorporation into any project requiring these particular characteristics without compromise on performance integrity nor operational consistency throughout its lifecycle usage span thereby fulfilling all expectations set forth by technically astute audiences needing factual clarity above all else when choosing components such as these critical elements powering modern infrastructures today tomorrow beyond alike!</p>
