<p>When selecting a switch for industrial or commercial applications, it&#39;s crucial to focus on the technical specifications that align with your operational needs. This particular switch is designed to meet rigorous demands, offering reliability and efficiency in various settings.</p><p>Operating at a rated voltage of 400 VAC and a current of 4 A, this switch provides robust performance suitable for numerous industrial environments. The housing is constructed from die-cast light alloy, which is painted for additional protection and durability. This material choice ensures longevity and resilience in challenging conditions.</p><p>The device boasts an IP65 degree of protection, making it dust-tight and resistant to water jets—ideal for environments where exposure to moisture or debris is common. Compliance with EN/IEC 60947-5-1 standards further assures its suitability for use in safety-critical applications.</p><p>This switch features a contact configuration of 1NO+1NC (one normally open and one normally closed), enabling versatile integration into control circuits. The slow-action switching type ensures precise operation, while the roller lever actuator type facilitates smooth engagement with minimal effort.</p><p>Designed for low-speed actuation at just 1 mm/min, it offers excellent control over mechanical operations where precision is paramount. The contacts are made from silver, providing superior conductivity and resistance to wear over time.</p><p>The fuse rating stands at 20 A gG D-fuse, offering adequate protection against overcurrent conditions without compromising performance. With a cable cross-section accommodation of up to 2.5 sq-mm, installation flexibility is assured across different setups.</p><p>Contact opening measures two gaps at 2.5 mm each—providing reliable separation during operation—and the unit supports an impressive mechanical life span of up to five million operations. This durability translates into reduced maintenance requirements and long-term cost savings.</p><p>In summary, this switch combines robust construction with advanced technical features suitable for demanding industrial applications where reliability cannot be compromised.</p>
