<p>When considering the technical requirements for your industrial or commercial project, this robust product offers a comprehensive set of specifications designed to meet demanding operational environments. With a rated voltage of 690 V and frequency compatibility across both 50 Hz and 60 Hz, it ensures versatility in various electrical systems. The non-illuminated design is straightforward yet effective for applications where illumination isn&#39;t necessary.</p><p>This component operates efficiently within a wide temperature range from -25&#176;C to 70&#176;C, making it suitable for diverse climate conditions. Additionally, its storage temperature extends from -40&#176;C to 85&#176;C, providing flexibility during transportation and storage phases.</p><p>For installation, the front mounting type simplifies setup processes in confined spaces or complex panels. The screw terminal type coupled with screw clamp connection ensures secure electrical connections with a tightening torque of 0.9 N-m that maintains stability under operational stress.</p><p>The device features an IP20 degree of protection, safeguarding against solid objects larger than 12 mm while maintaining ease of maintenance. Furthermore, its rated insulation voltage matches the operational voltage at 690 V, ensuring consistent performance without compromising safety standards.</p><p>With a contact configuration of 1NC (normally closed), this product is ideal for circuits where interruption is required unless actuated otherwise. It boasts a rated impulse withstand voltage of 6 kV which provides resilience against transient overvoltages often encountered in industrial settings.</p><p>Connecting capacity accommodates various wire types: flexible wires with ferrule or insulated ferrule (both single and double configurations) as well as solid wires ranging from 0.75 sq-mm to 2.5 sq-mm ensure adaptability across different wiring needs without sacrificing reliability.</p><p>The degree of pollution rating at IP3 indicates suitability for environments where dust and moisture levels are moderate but controlled—common in many manufacturing facilities or commercial installations.</p><p>Power loss is minimal at just 2.5 W which contributes to energy efficiency—a critical factor when assessing long-term operational costs in large-scale implementations. A wire stripping length requirement of only 8 mm facilitates quick preparation during installation phases ensuring swift integration into existing systems without unnecessary delays.</p><p>This product stands out by delivering on essential technical fronts crucial for successful deployment within industrial and commercial sectors—offering reliability through meticulous engineering tailored specifically towards users who prioritize functionality over frills.</p>
