## Long description

The Finder 20.21.8.230.4000 impulse relay is a robust electromechanical device engineered for the precise control of electrical circuits. Designed for professional use, this relay operates on a 230V AC coil voltage and supports a switching current of up to 16A. Its compact design and reliable switching mechanism make it a standard solution for modern electrical distribution boards and automation systems.
Advantages
This impulse relay offers exceptional durability and consistent performance in demanding electrical environments. By utilizing a bistable switching principle, it ensures that the circuit state is maintained without continuous power consumption by the coil, which contributes to energy efficiency. The high-quality materials used in its construction provide long-term operational reliability and resistance to mechanical wear, making it suitable for frequent switching operations in residential and commercial lighting control.
Suitable for
Lighting control systems in hallways and staircases
Automation of electrical circuits in residential buildings
Integration into smart home distribution panels
Industrial control applications requiring pulse-based switching
When it may not be suitable
This device is not intended for use in high-voltage industrial power distribution systems exceeding its rated capacity. It is also not suitable for environments with extreme moisture or corrosive atmospheres unless housed in an appropriate protective enclosure.
Key specifications
Rated current: 16A
Coil voltage: 230V AC
Contact configuration: 1 NO (Normally Open)
Mounting type: DIN rail
Color: Grey
How to use
The relay is designed for installation on a standard 35mm DIN rail within an electrical distribution cabinet. Wiring should be performed by a qualified professional in accordance with local electrical regulations. The coil terminals are connected to the control circuit, typically triggered by a momentary push-button, while the load terminals are wired in series with the lighting or equipment circuit. Each pulse received at the coil input toggles the state of the output contact.
What to consider before purchase
Ensure the coil voltage matches your control circuit voltage
Verify that the load current does not exceed the 16A rating
Check available space on the DIN rail within your enclosure
Confirm compatibility with your existing push-button control wiring
Usage recommendations
For optimal longevity and safety, ensure that all connections are tightened to the manufacturer's specified torque. Avoid exceeding the maximum switching frequency to prevent premature contact degradation.
