Harmony XB5AD33 22.5mm Black 3-Position Maintained Selector Switch - 2 NO Contacts, IP67/IP69/IP69K
High-quality Harmony XB5 series 3-position selector switch designed for precise control in industrial and commercial applications, commonly used in motor control centers. This black selector switch features a 22.5 mm mounting diameter and provides three distinct selection options at 45-degree intervals, typically marked "HAND OFF AUTO" for intuitive operation. Its maintained (stay put) operator ensures that the switch remains in the selected position until manually changed, making it ideal for continuous control functions. The switch comes with a durable plastic housing and is equipped with 2 Normally Open (NO) contact types for reliable circuit control.
Technically, the XB5AD33 is engineered for robust performance and safety. Its slow-break contact operation ensures controlled circuit interruption. The contacts are made of silver alloy (Ag/Ni), providing excellent conductivity and durability. It can withstand a conventional free air thermal current of 10 A and has a rated insulation voltage of 600 V, with an impulse withstand voltage of 6 kV. The operational current ratings vary for AC-15 (e.g., 3 A at 240V) and DC-13 (e.g., 0.1 A at 600V), ensuring suitability for diverse electrical loads. Connectivity is made easy with screw clamp terminals that support various cable sizes. The switch offers exceptional resistance to environmental factors, boasting IP67, IP69, and IP69K degrees of protection, alongside NEMA 13 and NEMA 4X ratings, making it highly resistant to dust, water, and even high-pressure washdowns (up to 1015.3 psi). Its mechanical durability is rated at 1,000,000 cycles, ensuring a long operational life. The XB5AD33 also exhibits strong resistance to vibrations and shocks, complying with IEC standards.
This 3-position selector switch is particularly well-suited for wash tunnel motor control centers, where operators need a clear and reliable way to switch between manual, off, and automatic modes for equipment. Its robust construction and high IP ratings ensure it can withstand the harsh conditions often found in such environments, including moisture and frequent cleaning. The intuitive "HAND OFF AUTO" markings make it easy to use, enhancing operational efficiency and safety.
