## Long description

The Relpol RPB-1ZI-U24 is a high-performance bistable relay engineered for efficient and reliable switching in demanding electrical circuits. This device is specifically designed to maintain a stable state, making it an essential component for power management and industrial automation systems. With a robust 120A switching capacity and a 20ms pulse duration, it provides consistent performance in applications requiring precise control over electrical loads.
Advantages
The primary advantage of this bistable relay is its ability to maintain its contact position without continuous power consumption, which significantly improves energy efficiency in control systems. Its high current capacity allows it to handle substantial electrical loads, while the 24V AC/DC compatibility offers versatility for various control voltage environments. The durable construction ensures long-term operational stability, reducing the need for frequent maintenance in industrial settings.
Suitable for
Industrial automation systems
Power management and distribution circuits
Lighting control systems requiring latching functionality
Building automation and smart infrastructure
When it may not be suitable
This relay is not intended for applications requiring high-frequency switching or rapid cycling, as the bistable mechanism is optimized for stable state operation rather than continuous toggling. It is also not suitable for circuits exceeding the specified 120A current rating or those operating outside the 24V AC/DC voltage range.
Key specifications
Contact configuration: 1NO (Normally Open)
Rated current: 120A
Pulse duration: 20ms
Operating voltage: 24V AC/DC
Switching type: Bistable
How to use
The relay should be installed by a qualified professional in accordance with local electrical regulations. Connect the control circuit to the coil terminals, ensuring the 24V AC/DC supply is correctly applied. The 20ms pulse is sufficient to trigger the internal latching mechanism. Ensure that the load circuit is connected to the 1NO contact terminals, verifying that the total current draw does not exceed the 120A limit during operation.
What to consider before purchase
Verify that your control system provides a 24V AC/DC signal.
Ensure the load current does not exceed 120A.
Confirm that the application requires a latching (bistable) switching action.
Check available space in your electrical enclosure for proper mounting.
Usage recommendations
Always ensure that the power supply is disconnected before performing any installation or maintenance work on the relay. Regularly inspect the terminal connections to ensure they remain tight and free from oxidation to maintain optimal electrical conductivity.
