Bistable contactor 25A 1-pole, 1-module RBS225-10-230V AC 002464101

Bistable Contactor – Reliable Circuit Switching

The RBS225-10-230V AC bistable contactor is a compact device designed for remote switching of electrical circuits. Its design, occupying only one module on a DIN rail, allows for efficient use of space in the distribution board. This is particularly important when designing installations in limited spaces. The device is characterized by a rated current of 25A and a control voltage of 230V AC, making it a universal solution for many applications.

Construction and principle of operation

This contactor, thanks to its bistable design, maintains its state (on or off) even after the control voltage is lost. This means that a short-term application of the control voltage is required to change the state of the contacts – it does not need continuous power to maintain its position. This solution minimizes power consumption and increases system reliability. Mounting is done on a standard DIN rail, which facilitates installation and device replacement.

Application and benefits

This contactor is used in home automation systems, lighting control, heating control and other applications requiring remote circuit switching. Its compact size and high reliability make it ideal for both professional installers and end users. The use of normally open (NO) and normally closed (NC) contacts allows for flexible adaptation to specific installation needs.

• Compact size: Occupies only 1 module on a DIN rail – saving space in the distribution board.
• Bistability: Maintains state after loss of control voltage – minimizing power consumption and increased reliability.
• Universal control voltage: Adapted to work with a voltage of 230V AC – wide range of compatibility with typical electrical installations.
• Easy installation: Mounting on a standard DIN rail – quick and easy installation.
• Rated current 25A: Allows handling of medium power loads.
• Wide supply voltage range: From 440V to 440V AC - ensures compatibility with various power systems.
