Contactor 8V AC/DC 1 NO + 1 NC CR2011008 193909

Compact installation contactor for low-voltage systems

The Eaton CR2011008 installation contactor is a professional solution designed for controlling circuits with a voltage of 6.8-8.8V AC/DC. The device features a compact design with a width of only 17.5 mm (one DIN module) and an installation depth of 60 mm, allowing for efficient space management in electrical distribution boards.

Construction and operating parameters

The device is equipped with a 1NO+1NC contact configuration (one normally open + one normally closed), providing universal control capabilities for different types of loads. The rated operating current is 20 A at an operating voltage of 400V, guaranteeing safe operation in typical domestic and industrial installations.

The compact build does not limit functionality - the device offers the possibility of additional equipment, allowing for the expansion of the control system according to individual needs. The IP20 protection rating protects against contact with live parts, ensuring user safety.

Energy efficiency and load capacity

One of the most important features of the product is the low power loss, which amounts to only 2.1 W of total heat dissipation. Such energy efficiency translates into minimal operating costs and a reduction in heat generation within the distribution board.

The device is characterized by high load capacity for various types of loads:

• Light bulbs: up to 1950 W
• Standard fluorescent lamps: up to 910 VA
• Fluorescent lamps with DUO-type compensation: up to 1160 VA
• Fluorescent lamps with parallel compensation: up to 232 VA

Application and user benefits

The contactor is ideal for building automation systems where lighting or other loads must be controlled using low, safe voltage. The universal AC/DC power supply eliminates the need for additional rectifiers or power supplies.

The low mass (0.13 kg) facilitates installation and does not strain the structure of distribution cabinets. Compliance with the AC-1 utilization category according to the EN IEC 60947-4-1 standard guarantees safe operation with resistive loads, making the device a universal tool for professional installers and conscious end-users seeking reliable electrotechnical solutions.
