Rotary switch Schneider Electric Merten MEG3115-0000, 1P, 250 V AC, 10 A, metallic

The Schneider Electric Merten MEG3115-0000 rotary switch is a single-pole manual selector with a metallic finish designed for switching and control tasks in electrical installations. Rated for use on standard AC distribution circuits, it provides a compact mechanical solution for on/off and position selection functions in control panels, lighting circuits and equipment that require a robust, visible selector. The unit’s compact dimensions make it suitable for standard mounting cutouts and confined enclosures where a reliable single-pole switch is needed.

Advantages

This rotary switch offers a straightforward mechanical switching operation with a clear tactile feel and durable metallic appearance. Its single-pole design simplifies wiring for circuits that require isolation or selection of one conductor. The switch is intended for repeated manual operation and provides a reliable contact arrangement suited to general-purpose control and lighting circuits. The metallic finish enhances visual integration in industrial and commercial panels while resisting everyday wear.

Suitable for

• Manual control and selection in control panels
• Switching of lighting circuits and luminaires
• Equipment requiring a single-pole mechanical selector
• Applications with limited installation space or standard cutouts

Key specifications

• Poles: single-pole mechanical selector
• Rated voltage: suitable for 250 V AC circuits
• Rated current: suitable for currents up to 10 A in typical AC applications
• Finish: metallic appearance for panel integration
• Mounting: compact form factor for standard panel or enclosure installations

How to use

Install the rotary switch in a properly prepared cutout or panel opening following applicable electrical standards and local regulations. Connect the single switched conductor to the switch terminal and ensure the neutral or remaining conductors are routed according to circuit design. Securely fasten the switch to the panel and make sure all connections are tightened to the specified torque before energizing the circuit. Operate the knob manually to select the required position; confirm correct wiring with appropriate testing equipment before regular use.

Usage recommendations

Use the switch only within its rated voltage and current limits, and avoid exposure to excessive moisture or corrosive environments. Periodically inspect terminals for tightness and signs of wear if the switch is used in high-cycle applications. When integrating into safety circuits, follow relevant safety and isolation procedures.
