Bistable contactor 20A 4-pole (4-normally open), 2-module RBS420-40-230V AC 002464124

Bistable contactor – reliable switching in your installation

This 4-pole bistable contactor with a current of 20A is a solid solution for controlling electrical circuits. Designed for DIN rail mounting, it occupies only 2 modules, saving space in the distribution box. Its construction makes it ideal for both domestic and more demanding industrial installations.

Functionality and application

The RBS420-40-230V AC contactor is a pulse switch, meaning that the state change (on/off) occurs after a short control pulse. It has 4 normally open (NO) contacts, providing great flexibility in connecting various loads. Thanks to the 230V AC control voltage, it is compatible with most standard electrical installations. Manual operation (although not a standard feature) can be useful in emergency situations or during testing.

Design and parameters

The contactor is designed for durability and safety. Made of high-quality materials, it ensures reliable operation even in harsh conditions. The rated operating current is 20A, and the supply voltage range is 440…440V AC. The device width is 35 mm, and the mounting depth is 60 mm. It complies with IEC/EN 60669-2-2 standards, guaranteeing compliance with applicable safety regulations. An important aspect is also high resistance to vibration and shock – up to 3g and 15g respectively – which translates to a long service life of the device. The use of M4 screw terminals (main circuit) and M3 (control circuit) ensures secure connection of wires with a cross-section from 1 to 10 mm².
