<p>When it comes to ensuring the safety and reliability of electrical systems, choosing the right Molded Case Circuit Breaker (MCCB) is crucial. This particular MCCB is designed to meet the demanding needs of industrial and commercial applications, providing robust protection and performance.</p><p>With a rated current of 63 A, this MCCB offers dependable operation for various electrical installations. It supports both AC and DC applications with a rated voltage capacity of 690 VAC or 500 VDC, making it versatile for different power systems. The device boasts a rated impulse withstand voltage of 8 kV and an insulation voltage rating of 800 V, ensuring high-level protection against overvoltages.</p><p>The trip unit type is TMD (Thermal Magnetic), which combines thermal overload protection with magnetic short-circuit protection. This makes it suitable for environments where precise control over trip settings is required. The release type TM ensures that tripping occurs at predetermined thresholds to protect equipment from damage.</p><p>This MCCB&#39;s breaking capacity stands at an impressive 18 kA, providing confidence in its ability to interrupt fault currents effectively. Its front connection type allows easy installation and maintenance access, while the bolt terminal ensures secure connections.</p><p>Designed to fit seamlessly into existing setups, this MCCB has four poles and adheres to IEC60947-2 standards and approvals, guaranteeing compliance with international safety regulations. The degree of protection is IP20, indicating suitability for indoor use where there are no excessive dust or moisture conditions.</p><p>A notable feature is its compatibility with XT1B systems, expanding its functionality within integrated setups. With a weight of just 1.4 kg and a width of 101.6 mm, it&#39;s compact enough not to overcrowd panel spaces but substantial enough for reliable performance.</p><p>The rated frequency range covers both standard frequencies at 50/60 Hz. Additionally, the product supports a wide current setting range from 44.1 A up to its maximum rating of 63 A, allowing flexibility in various load conditions.</p><p>For those concerned about energy efficiency or heat dissipation within their system designs should note that this MCCB has a low power loss value of only 4.3 W—an important consideration in maintaining overall system efficiency without compromising on safety features.</p><p>Lastly but importantly when considering conductor sizes during installation: main circuit connecting capacity ranges between sizeable conductors from as small as approximately45 sq-mm up through larger ones measuring around80 sq-mm—ensuring adaptability across diverse wiring requirements typically encountered within commercial settings today!</p>
