Installation contactor with AC/DC coil CMUC24/25-04 137404

Installation contactor – reliable circuit switching

The CMUC24/25-04 contactor is a modular element designed for remote control of electrical circuits. It finds application in both home and commercial installations where frequent switching of loads is required. Its versatility stems from the ability to power the coil with both AC and DC voltage, providing flexibility in the choice of control system.

Design and operating parameters

The contactor is designed for mounting on a TH35 rail, which facilitates its integration with existing modular equipment. A width of 2 modules allows for efficient use of space in the distribution board. The rated current of 25A ensures safe operation with most typical loads, and the maximum switching capacity for incandescent lamps reaches 3000W. The device is characterized by the absence of audible noise, which is important in applications sensitive to interference.

Application and benefits

• Versatility: The ability to power the coil with AC or DC makes the contactor compatible with various control systems.
• Safety: Rated operating voltage of 440V AC and utilization category AC-1 guarantee safe operation in standard electrical installations.
• Convenient installation: Modular design and mounting on a TH35 rail facilitate and speed up installation.
• High reliability: Manufactured by a renowned manufacturer – EATON ELECTRIC SP.Z O.O. – ensures long-lasting and trouble-free operation of the device.
• Installation optimization: Thanks to four normally open contacts (4NC) the contactor allows you to control different circuits simultaneously, reducing the need to use additional elements.
• Compliance with standards: Meets the requirements of EN IEC 60947-4-1 standard, which confirms its safety and quality.
• Wide range of applications: ideal for controlling lighting, electric heaters, fans and other devices of a similar nature.
• Installation protection: Protects the circuit against overload and short circuit - like most circuit breakers in this class.

Additional information: The degree of protection IP20 indicates protection against accidental contact and against the ingress of solid objects with a diameter of more than 12.5 mm. The contactor does not have a slider for manual operation, which increases safety and prevents accidental activation of the circuit.
