Relpol RPB-1ZI-A230 Bistable Relay 1P 16A 230VAC

The Relpol RPB-1ZI-A230 is a high-performance 1-pole bistable relay engineered for precise switching in electrical installations. Operating at 230VAC with a rated current of 16A, this impulse relay is designed to maintain its state until the next control pulse is received. It is built to handle significant surge currents, specifically featuring a 120A impulse capability for 20ms, which makes it a reliable component for demanding control circuits and automation systems.

Advantages

This bistable relay offers exceptional operational stability by requiring only a short electrical pulse to change its contact position, which significantly reduces energy consumption compared to standard contactors that require continuous coil power. Its robust construction ensures longevity and consistent performance in industrial and residential environments. The device is specifically optimized for efficient state switching, providing a dependable solution for complex lighting control and automation tasks where maintaining a state without constant power is essential.

Suitable for

• Lighting control systems in residential and commercial buildings
• Industrial automation and control circuits
• Remote switching of electrical loads via push-buttons
• Energy-efficient power management systems

When it may not be suitable

This relay is not intended for applications requiring high-frequency switching or continuous rapid cycling, as the mechanical bistable mechanism has specific operational limits. It is also not suitable for direct control of high-inductive loads that exceed the specified impulse current ratings or for environments with extreme moisture or dust without appropriate protective enclosures.

Key specifications

• Contact configuration: 1-pole (1P)
• Rated current: 16A
• Control voltage: 230VAC
• Impulse current capability: 120A for 20ms
• Operating principle: Bistable (impulse)

How to use

The relay should be installed by a qualified professional in a standard electrical distribution board. Connect the control circuit to the designated coil terminals and the load circuit to the switching contacts. Once installed, the relay changes its contact state each time a control pulse is applied to the coil. Ensure that the control signal duration is sufficient to trigger the internal mechanism but avoid continuous power application to the coil to prevent overheating.

What to consider before purchase

• Verify that the control voltage matches your existing system (230VAC).
• Ensure the load current does not exceed the 16A rating.
• Check the available space in your distribution board for mounting.
• Confirm that the impulse current of your load does not exceed the 120A/20ms limit.

Usage recommendations

For optimal longevity, ensure the relay is mounted in a dry, ventilated environment and protected from excessive vibration. Regularly inspect the terminal connections to ensure they remain tight and free from oxidation.
