Installation contactor with AC/DC coil CMUC230/25-22 137403

Installation contactor – reliable circuit protection

This Eaton installation contactor, catalog number 137403, is a key element in any electrical installation. Designed for frequent switching of circuits, it provides effective protection against overload and short circuit. Its modular design simplifies mounting on a TS35 rail, and a width of 2 modules allows for optimal use of space in the distribution board.

Versatile application and universality

The CMUC230/25-22 contactor is distinguished by its versatility thanks to the possibility of powering it with both AC and DC voltage. A rated current of 25A makes it ideal for protecting circuits with medium power. It has two normally open contacts (2NO) and two normally closed contacts (2NC), providing flexibility in control circuit configuration. The rated operating voltage is 440V AC, and the control voltage is in the range of 195.5 - 253V AC/DC.

Practical benefits for installers and users

• Easy installation: Modular design and a width of 2 modules facilitate quick and trouble-free installation on a TS35 rail.
• Universal power supply: The ability to power with both direct current (DC) and alternating current (AC) increases the range of applications.
• High reliability: Compliance with IEC 60947-4-1 standards guarantees the safety and long-term operation of the device.
• Wide range of applications: Ideal for protecting lighting (up to 1360 VA for fluorescent lamps, up to 3000 W for incandescent lamps) and other electrical devices.
• Compact dimensions: An installation depth of 69.5 mm allows for mounting in limited space.
• Noise-free operation: Ensures quiet operation, which is particularly important in residential and office premises.
• AC-1 utilization category: This means that the contactor is designed for switching resistive or inductive loads without inrush current (e.g., heating).

This contactor is a solid solution for both professionals performing electrical installations and end-users looking for reliable protection of their devices. Its high quality of workmanship and compliance with applicable standards ensure long-term and safe operation.
