Relpol RPB-1PM-A230 Bistable Latching Relay 1P 16A 230V AC

The Relpol RPB-1PM-A230 is a high-quality 1-pole bistable latching relay engineered for efficient and reliable control of electrical circuits. Designed to operate at 230V AC with a 16A contact rating, this device provides a robust solution for managing power distribution. Its primary feature is the integrated memory functionality, which ensures the relay maintains its current switching state even in the event of a power failure, eliminating the need for constant coil energization.

Advantages

The primary benefit of the Relpol RPB-1PM-A230 is its bistable operation, which significantly reduces energy consumption since the coil does not require continuous power to hold the contact position. This design also minimizes heat generation within the control cabinet, contributing to a longer service life for the component and associated equipment. The relay is built to withstand demanding industrial environments, offering high switching reliability and consistent performance over time.

Suitable for

• Lighting control systems in residential and commercial buildings
• Industrial automation and process control sequences
• Building management systems requiring state retention
• Energy-efficient power switching applications

When it may not be suitable

This relay is not intended for applications requiring high-frequency switching or rapid pulse-width modulation, as the mechanical latching mechanism has physical limitations regarding operation speed. It is also not suitable for direct control of high-inductive loads that exceed the specified contact rating without the use of additional protection or contactors.

Key specifications

• Contact configuration: 1-pole (1P)
• Rated current: 16A
• Control voltage: 230V AC
• Operating mode: Bistable (latching)
• Memory function: State retention after power loss

How to use

The relay is designed for standard mounting within electrical distribution boards or control panels. Installation should be performed by a qualified professional in accordance with local electrical regulations. Connect the control signal to the designated input terminals and the load circuit to the output contacts. Once installed, the relay will toggle its state upon receiving a control pulse, maintaining that position until the next pulse is received.

What to consider before purchase

• Ensure the control voltage matches your system requirements (230V AC).
• Verify that the maximum load current does not exceed 16A.
• Check available space in your enclosure for proper DIN-rail mounting.
• Confirm that the application requires a latching function rather than a standard monostable relay.

Usage recommendations

For optimal performance and longevity, ensure that the relay is protected against voltage surges and that the electrical connections are tightened to the manufacturer's specified torque settings. Regular inspection of the contacts is recommended in high-duty cycle environments.
