<p>In the realm of industrial and commercial electrical systems, choosing the right Miniature Circuit Breaker (MCB) is crucial for ensuring safety and reliability. The MCB from the M300P series stands out with its robust specifications tailored to meet diverse technical requirements.</p><p>This MCB is engineered to handle a rated current of 40 A, making it suitable for various applications where moderate current protection is required. With a rated voltage of 415 V, it fits seamlessly into standard three-phase systems common in commercial settings. Its capacity to withstand impulse voltages up to 6 kV ensures resilience against transient over-voltages, which can occur due to lightning strikes or switching surges.</p><p>Safety and durability are further reinforced by its breaking capacity of 25 kA. This high breaking capacity allows the MCB to safely interrupt fault currents without damage, protecting both the circuit and connected devices. Conforming to IEC/EN 60947-2 standards, this product meets international safety and performance benchmarks.</p><p>The magnetic D curve type provides delayed tripping characteristics ideal for inductive loads with high inrush currents such as motors or transformers. This feature minimizes unnecessary interruptions while maintaining protection against overloads and short circuits.</p><p>Installation is straightforward thanks to its DIN rail mounting type, which offers flexibility and ease during setup or maintenance tasks. The device’s compact dimensions—35 mm width, 88 mm height, and 69 mm depth—allow efficient use of space within control panels.</p><p>Operating reliably across a wide temperature range from -40&#176;C to 70&#176;C enhances its versatility in different environmental conditions—from cold storage facilities to heated industrial environments. It carries an IP3 degree of pollution rating indicating suitability for environments where non-conductive pollution could be present.</p><p>Constructed with practicality in mind, this MCB features a tightening torque requirement of just 2.8 N-m for secure connections without excessive force. Weighing only 0.248 kg, it balances sturdiness with ease of handling during installation.</p><p>Visually distinguished by its RAL 7036 grey housing color, it blends well with most electrical enclosures while providing clear identification within complex installations.</p><p>For professionals seeking reliable circuit protection that aligns with Australian standards while offering robust performance across various applications—the M300P series delivers on all fronts effectively meeting industry demands.</p>
