<p>When selecting a Miniature Circuit Breaker (MCB) for your industrial or commercial needs, understanding the technical specifics is crucial. The MCB from the M300P series offers a robust solution designed to meet demanding electrical requirements with precision and reliability.</p><p>This single-pole MCB is engineered to handle a rated current of 4 A, making it suitable for various low-current applications. With a rated voltage of 240 V and an insulation capability up to 500 V, it ensures safe operation across standard electrical systems. The device can withstand impulse voltages up to 6 kV, providing resilience against transient overvoltages common in many environments.</p><p>A notable feature is its impressive breaking capacity of 100 kA, ensuring that the circuit breaker can safely interrupt high fault currents without damage. This makes it particularly valuable in settings where high fault levels might be encountered.</p><p>The MCB conforms to IEC/EN 60947-2 standards, guaranteeing compliance with international safety and performance criteria. Its magnetic D curve type allows for effective protection against short-circuits while minimizing nuisance tripping during normal operational peaks.</p><p>Regarding installation and maintenance, this MCB mounts effortlessly onto a DIN rail system, streamlining setup processes in control panels or distribution boards. The specified tightening torque of 2.8 N-m ensures secure connections without risk of overtightening.</p><p>Physically compact yet sturdy, the dimensions are practical: a width of just 17.5 mm allows for efficient use of space; its height stands at 88 mm with a depth of 66.7 mm—ideal for modern panel designs where space conservation is key. Weighing only 0.124 kg further adds to its ease-of-handling during installation.</p><p>Built to endure harsh conditions, this device operates reliably within an ambient temperature range from -40&#176;C to +70&#176;C and has an IP3 degree of pollution rating which provides adequate protection against dust ingress under typical industrial conditions.</p><p>The housing comes in RAL 7036 Grey—a neutral shade that blends seamlessly into most equipment setups while maintaining professional aesthetics.</p><p>With these specifications in mind, the M300P series MCB emerges as a dependable choice for those requiring reliable circuit protection combined with straightforward integration into existing systems—all backed by rigorous industry standards compliance.</p>
