Modular contactor, DIN rail mounting, ST25-20

Modular contactor for safe and efficient circuit control

This modular contactor, designed for mounting on a 35 mm rail, is a reliable solution for both professional installers and end users. It provides effective protection and control of electrical circuits in residential and commercial buildings. Its compact design simplifies installation in distribution boards, and high-quality workmanship guarantees long-lasting and trouble-free operation.

Solid construction and parameters tailored to needs

The contactor is characterized by a rated current of 25 A and an operating voltage of 230 V AC. The rated switching capacity for incandescent lamps is as high as 4000 W, allowing it to handle a wide range of loads. Thanks to two normally open contacts, it enables control of various loads. The IP20 degree of protection provides basic protection against touch and ingress of solid objects. The contactor's design is designed for easy mounting on a standard TH35 rail, which significantly speeds up the installation process.

Versatile applications and benefits for installers and users

The ST25-20 modular contactor finds application in various electrical installations, such as:

• Lighting control

• Switching on/off heating devices

• Automation of ventilation systems

• Applications in light industry and home

For installers this means:

• Quick and easy mounting on a standard TH35 rail.

• Reliability and safety of operation, minimizing the risk of failure.

• Compact dimensions allowing for optimal use of space in the distribution board (2 module width).

For end users this means:

• Safe and efficient control of electrical devices.

• Long-lasting and trouble-free operation of the device.

• Peace of mind resulting from the use of high-quality components.

Additional information: The contactor does not have a slider for manual operation or day/night function, which simplifies its operation and increases reliability. The control voltage is the same as the supply voltage (230 V AC), eliminating the need for additional control elements in many applications. The lack of additional equipment means a simpler design and a lower risk of failure related to additional modules or accessories.
