<p>When selecting a switch for industrial and commercial applications, the technical specifications are paramount. This product is designed to meet rigorous demands with its robust construction and reliable performance.</p><p>Operating at a rated voltage of 400 VAC and a current of 4 A, this switch is suitable for various electrical systems, ensuring compatibility with standard setups in industrial environments. The grey cast iron housing, galvanized for additional protection, provides durability and resistance against harsh conditions. Its IP65 degree of protection ensures that the switch is dust-tight and protected against water jets from any direction, making it ideal for challenging environments where exposure to elements is inevitable.</p><p>Compliant with EN IEC 60947-5-1 standards, this switch meets international safety requirements, providing peace of mind regarding operational safety and reliability. The contact configuration includes one normally open (NO) and one normally closed (NC) contact, allowing for versatile application possibilities depending on your circuit needs.</p><p>The slow action switching type ensures precise control over operations. This feature can be crucial in applications requiring gradual engagement or disengagement to prevent sudden surges or mechanical stress on connected components. With an actuator type featuring a plunger mechanism, the switch offers straightforward actuation with minimal effort required.</p><p>Designed to function effectively even at low actuating speeds down to 1 mm/min, it caters well to precision operations where speed control is critical. The contacts are made from silver material known for excellent conductivity and resistance to corrosion—properties essential for maintaining reliable electrical connections over time.</p><p>For added safety in electrical circuits, the fuse rating stands at 16 A gG D-Fuse which helps protect against overloads by interrupting excessive currents that could potentially cause damage or hazards. The recommended cable cross-section is 1.5 sq-mm ensuring adequate current carrying capacity without overheating risks.</p><p>The contact opening measures two instances of 6 mm each providing sufficient space for secure connection points while maintaining compactness within installations. With an impressive mechanical life expectancy of up to ten million operations this switch promises longevity reducing downtime due to maintenance or replacements—a significant advantage in high-demand settings where continuous operation is expected.</p><p>This combination of features makes it an appealing choice for professionals seeking reliability efficiency and compliance all packed into one device tailored specifically towards demanding industrial applications.</p>
