Installation contactor with AC/DC coil CMUC230/25-40 137309

Installation contactor – reliable protection and circuit control

The CMUC230/25-40 contactor is a modular element designed for reliable switching of electrical circuits. It finds application in both home and commercial installations where high functionality and safety are required. The device is characterized by its versatility thanks to the possibility of powering it with both alternating current (AC) and direct current (DC).

Construction and operating parameters

The contactor is designed for mounting on a TH35 rail, occupying only 2 modules in width. Its rated current is 25A, allowing for safe control of most typical loads. The rated operating voltage is 440V AC, and the control voltage can range from 195.5 to 253V AC/DC – ensuring compatibility with various control systems. Equipped with 4 normally open (NO) contacts, it enables the implementation of complex switching functions. Absence of audible noise ensures quiet operation of the device.

Applications and benefits

• Versatility: The ability to power with both AC and DC current makes the contactor ideal for a variety of applications.
• Compact dimensions: A width of only 2 modules makes it easy to install in tight switchboards.
• High reliability: The construction based on proven Eaton components guarantees long-lasting and trouble-free operation.
• Safety: Compliance with IEC 60947-4-1 standards provides protection against overload and short circuit.
• Universality: Suitable for controlling lighting, heating, ventilation and other electrical devices.
• Application in building automation: Ideal for smart home systems and process automation.

Additionally, this contactor is characterized by a high switching capacity: maximum 3000W for incandescent bulbs and 1360 VA for fluorescent lamps (and up to 2552 VA with DUO compensation). The mounting depth is 69.5 mm, which should be taken into account when planning the installation. The degree of protection IP20 provides basic protection against accidental contact.
