<p>When selecting a reliable switch for industrial or commercial applications, technical specifications play a crucial role in determining the right fit for your needs. This particular switch offers robust features designed to meet demanding environments while ensuring safety and efficiency.</p><p>Starting with its electrical characteristics, the switch is rated at 400 VAC with a current capacity of 4 A. These ratings make it suitable for various medium-power applications where consistent performance is essential. The inclusion of silver contacts ensures excellent conductivity and durability over time.</p><p>The housing material is made from grey cast iron, which has been galvanized to enhance its resistance against corrosion. This makes it ideal for harsh environments where exposure to moisture or chemicals could be an issue. Complementing this rugged construction is the IP65 degree of protection, which guarantees that the device is dust-tight and protected against water jets from any direction.</p><p>Adherence to standards such as ENIEC 60947-5-1 underscores the product&#39;s compliance with international safety and performance benchmarks. This assures users that they are investing in a component that meets rigorous industry standards.</p><p>In terms of mechanical operation, this switch features a slow action switching type with a roller plunger actuator. The slow action mechanism provides precise control over switching operations, essential in processes requiring gradual engagement or disengagement. With an actuating speed of just 1 mm/min, it offers meticulous control suitable for delicate tasks.</p><p>The contact configuration follows the normally closed (NC) setup, providing fail-safe operations by default—an important consideration in many automated systems where maintaining circuit continuity is critical during power failures or system shutdowns.</p><p>For enhanced safety measures, it incorporates a fuse rating of 16 A gG D-Fuse, offering additional protection against overloads and short circuits. The cable cross-section capability stands at 1.5 sq-mm, accommodating standard wiring sizes used across numerous installations.</p><p>Notably impressive is its mechanical life expectancy rated at 10 million operations—indicative of long-term reliability even under frequent usage conditions—a testament to its engineering quality and robustness.</p><p>Overall dimensions include dual contact openings at (2) 6 mm each—providing ample connectivity options without compromising on space efficiency within installation setups.</p><p>This combination of features positions this switch as an optimal choice for professionals seeking dependable components capable of enduring tough operational demands while adhering to stringent safety norms within their projects.</p>
