## Long description

The Eti-Polam MR-42 is a high-performance bistable impulse relay engineered for precise electrical circuit management. This device allows for the control of lighting or other electrical loads from multiple locations using momentary push-buttons. With a robust 16A contact rating and a versatile universal supply voltage range of 12-240V AC/DC, it provides a reliable solution for both residential and industrial electrical installations.
Advantages
The primary benefit of the MR-42 relay is its ability to maintain its state without continuous power consumption, making it an energy-efficient choice for long-term operation. Its universal voltage compatibility simplifies inventory management and installation, as it can be integrated into systems with varying power requirements without the need for additional transformers or adapters. The 2P configuration allows for the simultaneous switching of two independent circuits, enhancing the flexibility of your electrical design.
Suitable for
Lighting control systems in hallways and staircases
Industrial automation and control panels
Remote switching of electrical appliances
Energy management systems
When it may not be suitable
This relay is not intended for applications requiring high-frequency switching at extremely rapid intervals, as mechanical wear may occur over time. It is also not suitable for direct control of high-inductive loads that exceed the specified current rating without the use of additional contactors.
Key specifications
Contact rating: 16A
Supply voltage: 12-240V AC/DC
Configuration: 2P (Double Pole)
Mounting: DIN rail
Operating mode: Bistable impulse
How to use
The MR-42 is designed for standard DIN rail mounting within an electrical distribution board. Connect the control circuit to the input terminals using momentary push-buttons. Each press of the button toggles the relay state, switching the connected load on or off. Ensure that the supply voltage is within the specified range and that the load does not exceed the 16A limit before finalizing the wiring.
What to consider before purchase
Verify the total current draw of your connected loads
Ensure the DIN rail space is available in your distribution cabinet
Check that your control wiring is compatible with the impulse relay logic
Usage recommendations
For optimal longevity and safety, always ensure that the electrical connections are tightened to the manufacturer's torque specifications and that the device is protected by an appropriate circuit breaker.
