<p>When selecting a robust and reliable electrical component for your industrial or commercial setup, it’s essential to focus on the technical specifications that ensure performance and safety. This product offers a solid choice with its impressive ratings and practical design.</p><p>With a rated current of 250 A, this device is well-suited for demanding environments where consistent power delivery is crucial. Its dimensions—229 mm in width, 150 mm in height, and 236 mm in length—make it compact yet substantial enough to handle rigorous applications. Weighing in at 6.05 kg, it&#39;s engineered for stability without being cumbersome.</p><p>The rated voltage of 1000 V ensures that this product can manage high-voltage applications effectively. Its rated impulse withstand voltage of 12 kV adds an extra layer of protection against transient overvoltages, enhancing system reliability.</p><p>Designed with four poles, this unit supports complex circuit configurations while maintaining efficiency. The degree of protection is marked as IP20, indicating that it is safeguarded against touch by fingers or similar objects greater than 12 millimeters but not protected from water ingress—a factor to consider depending on your installation environment.</p><p>The IP3 degree of pollution rating means it&#39;s suitable for installations where only dry non-conductive pollution occurs; however, occasional condensation might be expected.</p><p>A screw clamp terminal type facilitates secure connections with minimal hassle during installation or maintenance processes. The tightening torque ranges from 15-22 N-m, ensuring firm connections without risk of damage to the terminals.</p><p>Power loss stands at a low 6.5 W which contributes to energy efficiency within your system&#39;s overall operation. Additionally, the air thermal current mirrors the rated current at 250 A providing consistency across operational conditions.</p><p>The open transition type indicates seamless switching capabilities essential for uninterrupted operations in dynamic systems where continuity is paramount.</p><p>Finally, the handle color being black may seem like a minor detail but offers easy identification amidst diverse components within an electrical panel or machinery setup.</p>
