Switch, Elektromet cam-switch star-delta 3P 25A IP65 with mounting plate (model 922511)

Cam-operated star-delta changeover switch by Elektromet, model 922511, is a three-pole manual selector designed for star-delta motor starting and phase configuration changes. The unit is rated for 25 A and housed in an IP65-rated enclosure that protects internal components from dust and water ingress. A supplied mounting plate enables straightforward and secure installation into motor control panels or on machinery frames.

Advantages

The switch offers reliable mechanical operation with a cam mechanism that provides positive detents and clear switching positions for star, delta and off. Its IP65 enclosure ensures durable performance in dusty or wet environments, reducing the need for additional protective housings. The included mounting plate simplifies assembly and alignment in control cabinets. Constructed for industrial use, the device supports easy manual intervention and maintenance access.

Suitable for

• Manual star-delta motor starting and phase reconfiguration
• Industrial motor control panels and starter cabinets
• Production machinery where robust manual switching is required
• Workshops and service areas for temporary bypass or testing operations

Key specifications

• Contact poles: 3-pole (3P) mechanical cam switch
• Rated current: 25 A
• Protection rating: IP65 (dust-tight and protected against water jets)
• Operation: Manual cam-operated mechanism with defined positions for star, delta and off
• Mounting: Supplied mounting plate for panel or surface installation
• Intended use: Designed for star-delta motor starting and phase changeover

How to use

Install the switch using the supplied mounting plate following local electrical installation rules and ensuring power is isolated before work begins. Connect the three phase conductors and the corresponding motor leads according to the wiring diagram for star-delta switching, making sure all terminals are tightened to the specified torque. Use the cam-operated lever to select between star, delta or off positions during commissioning or manual operation. Verify correct connections and functionality with the motor unloaded or using recommended test procedures prior to normal operation.

Usage recommendations

Ensure regular inspection of terminals and mechanical linkage for wear or loosening. Use the switch within its rated current and environmental limits; if installed in unusually harsh conditions consider additional local protection. Always follow applicable safety standards and isolate supply before maintenance.
