Description

<p>When selecting a Miniature Circuit Breaker (MCB) for your industrial or commercial needs, it&amp;#39;s crucial to focus on the technical specifications that ensure reliability and safety. This MCB is engineered to meet demanding requirements with precision.</p><p>The MCB is rated for a current of 63 A, making it suitable for various applications where medium-level current protection is necessary. With a rated impulse withstand voltage of 6 kV and an insulation voltage of 500 V, this device is robust against electrical surges and ensures safe operation in challenging environments.</p><p>Operating at a rated voltage of 415 VAC, this MCB supports three poles, providing comprehensive protection across multiple circuits. Its breaking capacity stands at an impressive 15 kA, ensuring effective interruption of fault currents without damage to the system.</p><p>Designed with versatility in mind, the degree of protection ranges from IP20 to IP40 depending on installation conditions. The screw clamp terminal type facilitates secure connections with a recommended tightening torque of 3 N-m. Its dimensions (width: 52.5 mm; height: 88 mm; depth: 69 mm) allow easy integration into standard panels.</p><p>Compliance with standards such as CSA 22.2 No. 235, IEC/EN 60947-2, and UL 1077 underscores its reliability and quality assurance internationally. Weighing only 0.372 kg, it offers ease of handling during installation or maintenance.</p><p>Part of the S300P series, this MCB operates efficiently within a frequency range of 50/60 Hz and maintains performance across ambient temperatures from -40 to +70&amp;#176;C—ideal for diverse climates found in Australia.</p><p>The Curve Type K characteristic caters well to inductive loads common in industrial settings by allowing higher peak currents before tripping—a critical feature when protecting motors or transformers.</p><p>Installation flexibility is enhanced by its DIN rail mounting type which allows straightforward setup while maintaining structural integrity under various conditions due to its dielectric test voltage rating at 2 kV.</p><p>With an arbitrary power supply connection option and any mounting position capability combined with wire stripping length set at optimal efficiency (14 mm), this breaker simplifies both initial setup and future adjustments if needed—making it adaptable yet reliable over time.</p><p>Finished in RAL7039 grey housing color—it not only looks professional but also blends seamlessly into most industrial control setups without drawing unnecessary attention away from functionality-focused design elements inherent throughout every aspect here presented today!</p>
