## Summary description

Eti-Polam WB-1UN is an impulse (latching) relay designed for DIN-rail mounting. Intended for remote switching of lighting and circuits with a momentary control signal, the unit toggles output state on each pulse. Supplied under MPN 002471514 and EAN 3838895722175, it suits electrical distribution panels and automation installations requiring compact, repeatable pulse control.

## Long description

Eti-Polam WB-1UN is an impulse (latching) relay designed for DIN-rail mounting, engineered to toggle an output circuit each time a brief control pulse is applied. The device is intended for use in electrical distribution panels and automation installations where compact, repeatable pulse control is required. Its design enables centralized switching of lighting and other loads from momentary push-buttons or control systems without the need for permanent coil excitation.
Advantages
The WB-1UN provides a stable latching function that changes the output state on every input pulse, reducing wiring complexity for multipoint switching. Its DIN-rail form factor saves panel space and allows straightforward installation in standard distribution enclosures. The relay offers reliable mechanical switching with clear ON/OFF state retention after control pulses, making it suitable for systems that require energy-efficient and low-power control logic.
Suitable for
Centralized lighting control in residential and commercial panels
Momentary-switch operation for stairways, corridors, and common areas
Integration with building automation and pulse-control systems
Remote toggling of circuits where a maintained coil is undesirable
Key specifications
Type: impulse (latching) relay for DIN-rail mounting
Operation: toggles output state on each momentary control pulse
Mounting: standard DIN-rail compatible housing for distribution panels
Application: switching of lighting and general-purpose electrical circuits
Control interface: designed for use with momentary push-buttons or pulse signals
How to use
Install the relay onto a standard DIN-rail inside the distribution board and connect the supply, load, and control conductors according to the wiring diagram supplied by the manufacturer. Use momentary push-buttons or pulse outputs from control equipment to activate the input; each pulse will change the relay’s output to the opposite state. Verify correct line and load isolation before applying power and perform functional tests after wiring to confirm the toggle action.
Usage recommendations
For reliable operation, place the relay in a dry, ventilated panel and ensure terminal screws are tightened to specified torque values. Use appropriately rated conductors and protection devices (fuses or circuit breakers) for the connected loads. When integrating with automation controllers, confirm that control pulse voltage and duration match the relay’s input requirements to ensure consistent toggling.
