Bistable contactor 25A 4-pole (4-normally open), 2-module RBS425-40-230V AC 002464125

Bistable contactor – reliable switching in your installation

This 4-pole bistable contactor with a rated current of 25A is a solid solution for controlling electrical circuits. DIN rail (TH35) mounting ensures easy installation and integration with existing infrastructure. The 2-module design allows for efficient use of space in the distribution board. The device operates at 230V AC, making it compatible with most standard installations.

Functionality and application

The RBS425-40-230V AC contactor stands out with its unique bistable function, which means it maintains its state (on or off) without the need for continuous coil power. It requires a short control voltage pulse (207…253V AC) to change state, which translates to energy savings and increased device life. Thanks to four normally open contacts (4NO), it allows you to control various loads in a single circuit. Manual operation provides additional control over device operation.

Construction and technical parameters

The contactor is designed for durability and reliability. The rated operating current is 25A, and the rated operating voltage is 440V AC. The width of the device, 70mm (2 modules), makes it easy to mount even in tight distribution boards. The solid construction provides resistance to shocks (up to 15g) and humidity (up to 95% RH). Protection class IP20 guarantees safe use in standard environmental conditions. The used screw terminals M4 for the main circuit and M3 for the control circuit ensure secure connections of wires with a cross-section of up to 110mm².
