Bistable contactor 25A 4-pole (3 normally closed, 1 normally open), 2-module RBS425-31-230V AC 002464134

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. Its construction, with three normally closed contacts and one normally open contact, provides flexibility in configuration and adaptation to various applications. DIN rail mounting simplifies installation and integration with existing infrastructure.

Construction and application

The RBS425-31-230V AC contactor is designed to operate with a control voltage of 207…253V AC (50/60Hz) and a supply voltage of 440V AC. The bistable design means that the contactor maintains its position (on or off) without the need for continuous coil power, which translates to energy savings. A width of 2 modules makes it compact and ideal for switchboards with limited space. Manual operation is an additional advantage in service or emergency situations.

Key features and benefits

• Bistability: Maintaining the switching state without continuous power consumption – reduces energy consumption and extends the life of the device.
• DIN rail mounting: Quick and easy mounting in standard electrical switchboards.
• Compact dimensions: Only 2 modules wide allows for efficient use of space in control cabinets.
• Versatility: Three normally closed contacts and one normally open contact provide a great deal of freedom in circuit configuration.
• Durability: Rated current of 25A ensures reliable operation even under higher loads.
• Manual operation: Allows testing and control of the contactor status without the need to supply control voltage.
• Screw terminals: Provide a secure connection for wires with a cross-section of up to 110mm². Tightening torque of 1.2Nm guarantees connection stability.

This contactor is an optimal choice for both professional installers and end-users looking for a reliable and efficient solution for controlling electrical circuits. Its solid construction, compact dimensions and functionality make it an ideal element of any modern electrical installation.
