Modular contactor ST25-31/24 modular contactor 3NO+1NC contacts I=25A coil voltage U=24V AC 2 modules ST25-31-24V

Modular contactor for mounting on 35mm rail

This modular contactor, designated ST25-31/24V, is a reliable solution for controlling electrical circuits. It is designed for direct mounting on a standard 35mm rail, which significantly simplifies and speeds up installation. Its compact design – occupying only 2 modules – allows for efficient use of space in switchgear cabinets.

Construction and operating parameters

The contactor operates at 24V AC and is characterized by a rated current of 25A. It has a contact configuration of 3NO (normally open) + 1NC (normally closed), providing flexibility in connecting various loads. The rated operating voltage is 230V AC. The use of an AC-powered coil guarantees compatibility with most standard electrical installations.

Application and benefits

The ST25-31/24V contactor finds application in a wide range of applications, from home automation to industrial control systems. Its solid construction and high durability (1x10⁵ electrical switching cycles, 1x10⁶ mechanical) ensure long-lasting and trouble-free operation. The maximum switching capacity for incandescent lamps is as high as 9000W, making it an ideal solution for controlling lighting and other devices with high power consumption. The IP20 protection class provides basic protection against touch and ingress of solid objects.
