<p>The S300P series Miniature Circuit Breaker (MCB) is a robust and reliable solution for industrial and commercial electrical circuit protection. Designed to handle a rated current of 40 A, this MCB efficiently safeguards your electrical systems against overloads and short circuits, ensuring operational safety and longevity.</p><p>Featuring a dual-pole configuration, the S300P MCB offers enhanced protection by isolating both the live and neutral lines. This is particularly beneficial in applications where comprehensive disconnection is essential. With an impressive breaking capacity of 15 kA, it can effectively interrupt fault currents to prevent damage to connected equipment.</p><p>The degree of protection provided by this MCB ranges from IP20 to IP40, making it suitable for indoor environments where dust ingress needs to be minimized. The screw clamp terminals ensure secure connections with a tightening torque of 2.8 N-m, providing reliability in high-vibration settings.</p><p>Complying with international standards such as CSA 22.2 No. 235, IEC/EN 60947-2, and UL 1077, the S300P MCB meets rigorous safety requirements for global markets. Its curve type K characteristic makes it ideal for protecting inductive loads like motors or transformers that may experience high inrush currents.</p><p>Designed for easy installation on standard DIN rails, the S300P accommodates flexible mounting positions without compromising performance or accessibility. The wire stripping length requirement is set at 14 mm for optimal connection integrity.</p><p>Withstanding ambient temperatures ranging from -40&#176;C to +70&#176;C during operation ensures that this breaker performs reliably across diverse climatic conditions typical in Australia’s varied landscapes. Furthermore, its arbitrary power supply connection design allows versatile integration into existing setups without extensive reconfiguration.</p><p>Electrical durability extends up to an impressive 20,000 cycles offering long-term service life even under frequent switching operations—a testament to its engineered resilience.</p><p>The housing color RAL 7039 Grey provides a professional appearance while blending seamlessly into most industrial environments without standing out unnecessarily.</p><p>In summary, the S300P series MCB delivers dependable performance tailored towards demanding applications requiring robust circuit protection solutions adhering strictly to industry standards—an excellent choice when reliability cannot be compromised.</p>
