<p>When it comes to industrial automation and control systems, reliability and durability are key. This particular device is a robust switch designed for demanding environments, offering a combination of precision and resilience that meets the needs of professionals in the field.</p><p>Rated at 400 VAC with a current capacity of 4 A, this switch is well-suited for applications requiring dependable performance under high voltage conditions. The housing is constructed from grey cast iron, which has been galvanized to enhance its resistance against corrosion and wear. This ensures longevity even in harsh industrial settings.</p><p>The switch boasts an impressive IP65 rating, providing excellent protection against dust ingress and water jets from any direction. This makes it ideal for use in environments where exposure to moisture or particulate matter could be an issue.</p><p>Compliance with EN/IEC 60947-5-1 standards highlights its adherence to international safety and operational benchmarks, ensuring peace of mind when integrated into larger systems. The contact configuration features normally closed (NC) contacts made from silver, known for their superior conductivity and resistance to oxidation.</p><p>A slow action switching type provides precise control over operations, making it suitable for applications where gradual engagement is required. Coupled with a roller lever actuator type, it allows smooth mechanical interfacing in diverse installations.</p><p>Operating at an actuating speed as low as 1 mm/minute underscores its suitability for delicate operations where precise movement tracking is necessary. Furthermore, the contact opening spans two distinct openings each measuring 6 mm—facilitating versatile connectivity options.</p><p>For enhanced safety measures, this product incorporates a fuse rating of 16 A gG D-Fuse which offers reliable circuit protection by preventing overloads or short circuits within your system setup. With a cable cross-section specification of 1.5 square millimeters—installation flexibility across different wiring configurations becomes straightforward without compromising on electrical integrity.</p><p>Perhaps most notably though—the mechanical life expectancy stands at an astounding ten million operations! Such longevity assures minimal maintenance interventions over extended periods—translating directly into reduced downtime costs while maximizing productivity levels within your operation framework.</p>
