Modular contactor ST25-04 modular contactor 4NC contacts I=25A coil voltage U=230V AC 2 modules

Modular contactor for DIN rail mounting

This modular contactor, designed for mounting on a 35mm rail, is a reliable solution for controlling electrical circuits. Designed for both professional installers and end users, it provides safe and efficient switching of loads. Its compact design (only 2 modules wide) saves space in the distribution board.

Construction and application

This contactor is an electromagnetic element that allows remote switching of electrical circuits. It finds application in home installations, commercial buildings and light industry. Thanks to the configuration of four normally closed contacts (4NC), it is ideal for applications where the load needs to be disconnected after the control voltage is lost. For example, it can be used to control lighting, heaters or other electrical devices.

Advantages and characteristic features

• High reliability: Made of high-quality materials, guarantees long-lasting and trouble-free operation.
• Compact dimensions: A width of only 2 modules makes it easy to install even in tight distribution boards.
• Safety: Compliance with IEC 61095 ensures a high level of safety. Protection class IP20 protects against accidental contact.
• Adapted to work in difficult conditions: Operating temperature range from -25°C to +50°C allows its use in various environments.
• Easy installation: Quick and easy mounting on a standard 35mm rail – does not require specialized tools.
• Rated operating current 25A: Allows controlling loads up to 9kW (AC1) and 2.2kW (AC3).
• Coil voltage 230V AC: Standard coil supply voltage facilitates integration with existing electrical installations.
• Durability: Electrical switching durability is 1x10⁵ cycles, and mechanical – 1x10⁶ cycles, which ensures long life of the device.
• Screw terminals: Allow connection of wires with a cross-section up to 6 mm².

The rated operating voltage is from 230 to 230V, and the rated control voltage is also 230V AC. The contactor has a rated operating current of 25A and four normally open contacts. Its width is only 2 modules, and the degree of protection is IP20. The maximum switching capacity for incandescent lamps is 9000W.

Remember that proper selection of the contactor for a specific application is crucial to ensure the safety and reliability of the electrical installation. If in doubt, consult a specialist.
