Bistable contactor 25A 2-pole, 1-module RBS225-20-230V AC 002464104

Bistable contactor for DIN rail mounting

This two-pole bistable contactor with a current of 25A is a compact solution for controlling electrical circuits. Its modular design (1 module) simplifies mounting on a DIN rail, saving space in the distribution board. This contactor is particularly useful in applications requiring maintaining the state (on/off) after the control voltage is lost – hence its name “bistable”.

Characteristics and application

The RBS225-20-230V AC contactor is designed to operate with a control voltage of 207-253V AC and a supply voltage of 440V AC. Thanks to two normally open contacts, it allows controlling two independent circuits. Its construction allows manual switching of the state, which can be useful during testing or maintenance. A width of only 17.5 mm makes it ideal for installation in tight spaces.

Advantages and benefits

• Bistability: Maintains state after loss of control voltage – no need for continuous coil power. This translates to energy savings and increased system reliability.
• Compact dimensions: 1 module width allows for efficient use of space in the distribution board.
• DIN rail mounting: Simplifies and speeds up installation, and also ensures device stability.
• Manual control: The ability to manually switch the contactor state facilitates testing and maintenance of the installation.
• Rated current 25A: Allows controlling circuits with higher current draw.
• Durability: Designed for long-term operation – withstands 10,000 electrical cycles and 100,000 mechanical cycles.
• Compliance with standards: Meets the requirements of IEC/EN 60669-2-2, which guarantees safety and reliability.

Additional information: the mounting depth is 60 mm, and the control voltage frequency is in the range of 50-60 Hz. The contactor has two normally open contacts (NO).
