<p>The S300P series Miniature Circuit Breaker (MCB) offers a robust solution for industrial and commercial electrical systems. Designed to handle demanding environments, this MCB is built with precision and reliability in mind.</p><p>Rated for a current of 4 A, it operates efficiently within systems up to 415 VAC. Its rated insulation voltage stands at 500 V, ensuring safety and performance under varied conditions. The product&#39;s breaking capacity is an impressive 15 kA, making it suitable for applications where high fault levels are expected.</p><p>One of the standout features of this MCB is its dual-pole configuration. This design enhances safety by providing additional protection against electrical faults. The device also boasts a short circuit capacity of 25 kA, further underscoring its capability to withstand significant electrical stress.</p><p>In terms of physical specifications, the MCB measures 35 mm in width, 88 mm in height, and has a depth of 69 mm. It weighs approximately 0.248 kg, making it relatively compact yet sturdy enough for various installations. Its degree of protection is rated at IP20/IP40, offering adequate defense against dust and limited ingress from other elements.</p><p>The S300P series adheres to several international standards including CSA 22.2 No. 235, IEC/EN 60898-1, IEC/EN 60947-2, and UL 1077—testament to its quality and compliance with global safety benchmarks.</p><p>Engineered with user convenience in mind, this MCB features screw clamp terminals that provide secure connections with a tightening torque specification of up to 2.8 N-m. The wire stripping length required is just 14 mm which simplifies installation processes considerably.</p><p>With an operational ambient temperature range from -40&#176;C to +70&#176;C and dielectric test voltage standing at 2 kV—it’s clear that this unit can perform reliably across diverse environmental conditions without compromising on durability or functionality.</p><p>The D curve type ensures precise tripping characteristics suited for specific load types while maintaining high selectivity within complex circuits—a crucial factor when considering system coordination needs.</p><p>Designed for easy integration into existing setups via standard DIN rail mounting; it&#39;s versatile enough for any position or power supply connection method chosen by the installer thanks largely due arbitrary connection options available alongside universal mounting positions supported here too!</p><p>Finally housed elegantly within RAL7039 grey exterior casing not only does look aesthetically pleasing but also helps blend seamlessly into most control panels found commonly across industries today completing package perfectly overall!</p>
