<p>The MCCB (Moulded Case Circuit Breaker) you&#39;re considering is a robust solution designed for industrial and commercial applications. With a rated current of 52 A, it is well-suited to handle moderate electrical loads while ensuring safety and reliability. The device&#39;s rated voltage spans both AC and DC systems, accommodating up to 690/750 VAC/VDC, making it versatile across various power supply configurations.</p><p>One of the standout features of this MCCB is its impressive breaking capacity of 36 kA. This ensures that in the event of a fault condition, such as a short circuit, the breaker can effectively interrupt high fault currents without sustaining damage or compromising system integrity. Complementing this capability is its rated short circuit current range from 260-520 A, providing flexibility in different operational scenarios.</p><p>Safety and durability are further enhanced by its IP20 degree of protection, which safeguards against solid objects larger than 12 mm but does not protect against water ingress. For installation convenience, it employs a front connection type with bolt terminals, supporting main circuit connecting capacities between 85-200 sq-mm. This allows for secure and efficient connections tailored to your specific wiring needs.</p><p>The MCCB adheres to IEC60947-2 standards and approvals—a testament to its compliance with international safety and performance benchmarks. Its release type M indicates manual operation capabilities suitable for precise control over circuit interruptions.</p><p>In terms of physical dimensions, the breaker measures 105 mm in width and weighs approximately 2.5 kg—compact enough for integration into existing panels without demanding excessive space or structural modifications. Additionally, it has been engineered with a power loss rating of just 5.3 W at full load conditions—an energy-efficient choice that minimizes heat generation during operation.</p><p>This MCCB operates within standard frequency ranges of 50/60 Hz, aligning seamlessly with most power systems used in Australia today. It also boasts an impressive rated insulation voltage of up to 1000 V along with an impulse withstand voltage capacity reaching up to 8 kV—features indicative of superior insulation properties capable of enduring transient overvoltages commonly encountered in industrial environments.</p><p>Designed specifically for compatibility with XT4N systems adds another layer versatility; ensuring seamless integration into pre-existing setups equipped similarly configured components without requiring extensive adjustments or replacements elsewhere within your infrastructure setup process itself!</p><p>Overall if you&#39;re seeking reliable protection alongside adaptability across diverse applications then look no further than this particular model offering comprehensive solutions meeting all necessary criteria expected from mid-lifecycle products intended primarily professional use cases alike!</p>
