Schneider Electric Harmony XB4 3-Position Selector Switch, 2NO, 120V, 6A

The Schneider Electric Harmony XB4 3-Position Selector Switch is a robust and reliable industrial-grade component designed for precise control. This black voltage selector switch features a 3-position ±45° operator, allowing for clear, definitive switching actions between different circuit states. Engineered for demanding environments, it offers a remarkable 1,000,000-cycle mechanical durability, ensuring long-term performance and reduced maintenance needs.

Its construction prioritises both durability and electrical safety. The switch incorporates a chromium-plated metal bezel for corrosion resistance and silver alloy contacts for excellent conductivity and reliability. The slow-break contact operation function helps to minimise arcing, thereby protecting the contacts and extending the operational life of the switch. Terminations are made via secure screw clamp terminals, providing a reliable and vibration-resistant connection.

This switch is built to withstand harsh conditions, boasting an IP69K rating conforming to IEC 60529. This makes it resistant to high-pressure, high-temperature water jets, ideal for washdown areas in food and beverage processing or other wet industrial settings. It also features a high 6kV rated impulse withstand voltage conforming to EN/IEC 60947-1, offering superior protection against voltage surges.

With a compact 22mm mounting diameter, it is designed for easy installation into standard control panels and enclosures where space is at a premium. The 2NO (two normally open) contact configuration provides versatile switching capability for a variety of control applications.
