<p>When it comes to selecting the right Molded Case Circuit Breaker (MCCB) for your industrial or commercial needs, understanding the specifics can make all the difference. This MCCB is designed with precision and reliability in mind, offering a robust solution for various electrical systems.</p><p>At its core, this MCCB is rated for a current of 50 A, making it suitable for medium-load applications. The device boasts a high rated impulse withstand voltage of 8 kV and an insulation voltage of 800 V, ensuring durability against electrical surges and providing reliable insulation under demanding conditions. With a rated voltage capacity of up to 690 VAC or 500 VDC, this breaker is versatile enough to handle both AC and DC applications efficiently.</p><p>The thermal-magnetic (TM) release type paired with a thermal magnetic trip unit (TMD) ensures that the MCCB responds accurately to overloads and short circuits. It features an impressive breaking capacity of 70 kA which means it&#39;s well-suited to environments where high fault currents are possible.</p><p>Engineered with practicality in mind, this model includes four poles allowing comprehensive protection across multiple phases. The front connection type simplifies installation while maintaining accessibility for maintenance purposes. Additionally, bolt-type terminals offer secure connections that support cable sizes ranging from 45.5 sq-mm to 80 sq-mm.</p><p>With an IP20 degree of protection rating, this MCCB provides basic protection against solid objects larger than 12 mm but should be installed within appropriate enclosures when used in harsher environments. The compact design measures at just over 101 mm wide making it adaptable for space-constrained installations without compromising on performance.</p><p>Conforming to IEC60947-2 standards ensures compliance with international safety regulations while its compatibility with XT1H systems offers flexibility in system integration or upgrades. Weighing only 1.4 kg makes handling straightforward during setup or replacements; coupled with power loss efficiency at merely 3.7 W contributes towards energy conservation efforts—a key consideration in today&#39;s eco-conscious landscape.</p><p>Operating seamlessly across frequencies between 50 Hz and 60 Hz further enhances its adaptability across diverse settings whether locally here in Australia or abroad where different frequency standards may apply.</p><p>In summary: if you&#39;re seeking reliability combined with efficiency wrapped into one capable package then this particular MCCB stands out as an excellent choice fulfilling those criteria effectively—without unnecessary complexity yet delivering on essential technical requirements confidently expected by professionals within industry sectors alike!</p>
