Description

<p>For professionals in the electrical engineering and automation sectors, selecting the right Miniature Circuit Breaker (MCB) is crucial for ensuring safety and efficiency. The MCB from the M300P series stands as a reliable choice for industrial and commercial applications, offering robust features tailored to meet demanding requirements.</p><p>Starting with its core specifications, this MCB is designed to handle a rated current of 10 A. It operates efficiently within a voltage range up to 415 V, making it suitable for various heavy-duty applications. With a rated impulse withstand voltage of 6 kV and an insulation voltage of 500 V, it provides excellent protection against overvoltage conditions.</p><p>Safety is further enhanced by its impressive breaking capacity of 25 kA. This feature ensures that in case of short circuits or overloads, the circuit breaker can interrupt high fault currents without damage. The device adheres to IEC/EN 60947-2 standards, guaranteeing compliance with international safety regulations.</p><p>The design incorporates three poles, providing comprehensive coverage across different phases in electrical systems. Installation is straightforward thanks to its DIN Rail mounting type—a standard method that simplifies setup and maintenance processes.</p><p>In terms of physical dimensions, this MCB has been engineered with practicality in mind: measuring at a width of 52.5 mm, height of 88 mm, and depth of 69 mm. Its compact size does not compromise on performance but allows for efficient use of space within electrical panels.</p><p>Durability under varied environmental conditions is assured with an ambient temperature range from -40 to 70 degrees Celsius. Additionally, the IP3 degree of pollution rating indicates resilience against dust ingress—essential for maintaining reliability in less-than-ideal environments.</p><p>From an operational standpoint, users will appreciate the Magnetic D curve type which offers precise tripping characteristics suitable for protecting inductive loads such as motors or transformers that experience high inrush currents upon startup.</p><p>This model also supports both 50 Hz and 60 Hz frequencies—flexibility that accommodates various regional power supply standards globally. Furthermore, installation integrity is maintained through a tightening torque specification set at 2.8 N-m ensuring secure connections during setup.</p><p>Visually appealing yet functional—the housing comes in RAL 7036 grey—a neutral tone that blends seamlessly into most industrial settings while maintaining professional aesthetics.</p><p>Weighing just under half a kilogram (0.372 kg), this unit balances sturdiness with ease-of-handling during installation or replacement tasks—an essential factor when considering long-term use across multiple sites or projects.</p>
