Description
This Harmony XB4 modular black key selector switch (key no.455) has 2 positions, operates with a stay-put mechanism with key withdrawal on the left position. It has a metal bezel. This key selector switch provides a versatile interface for controlling your machines. It is easily installed into standard 22mm diameter cut-outs and connected to your control circuits with simple screw-clamp connections. It provides a secure manner for authorized staff to switch between process or machine operating modes. It is impact resistant, dust resistant, water resistant and vibration resistant thanks to its IP66 / IP67 / IP69 / IP69K, making it ideal for operation in harsh environments.
Features
- Built with the rugged Schneider Electric Harmony XB4 heavy-duty metal construction, this 22mm selector switch easily withstands high-impact industrial operations, mechanical shock, and extreme vibration. By eliminating the frequent replacement costs associated with brittle plastic alternatives, it guarantees long-lasting, reliable performance across your high-traffic motor control centers and factory floor machinery.
- Engineered as a 2-position, maintained key selector switch, this unit requires a standard Ronis 455 key to operate, with safe key withdrawal exclusively in the left-hand position. This provides a critical layer of physical lockout security for dangerous automated equipment, strictly limiting overrides to qualified maintenance personnel and actively preventing accidental or unauthorized startups.
- Boasting exceptional IP66, IP67, and IP69K ingress protection, this completely sealed unit is impenetrable to heavy industrial dust, temporary water submersion, and high-temperature, high-pressure cleaning jets. This makes it an uncompromising, fail-safe control component for strict hygiene environments like food and beverage processing facilities, wastewater treatment plants, and heavily exposed outdoor enclosures.
- This complete assembly includes a pre-installed, slow-break 1 Normally Open (NO) contact block featuring secure screw-clamp terminals that ensure vibration-proof wire retention. Its modular, snap-fit architecture is designed to drop universally into standard 22mm panel cutouts, saving panel builders and electricians valuable labor time during initial machine integration or emergency breakdown retrofits.
