Flush-mounted, 2-gang, screw-mount design reduces wall box depth and creates a neat, serviceable installation with minimal space impact. This supports efficient retrofits and new builds where fixture density matters, while ensuring safe grounding and secure wiring via screw terminals. The unit provides two outputs and two inputs at 230 V and 50 Hz, enabling independent control of lighting and ventilation loads with a maximum switching capability aligned to typical household and commercial circuits. A modest 0.3 W no-load power loss improves energy efficiency for continuously powered applications, lowering ongoing operating costs. Compatibility with flexTronics and free@home families shortens engineering time and reduces integration risk for automation projects, and the option to pair with 64891 UR-508 extension inserts offers scalable expansion. The design also accommodates 3-wire connections (neutral required) for common lighting configurations and supports ABB Comfort switch elements 64765-3..-508 and Watchdog sensors, delivering a cohesive control strategy.

FAQs
Install in a standard 2-gang flush-mounted enclosure using the provided screw terminals for two inputs and two outputs. Connect live and neutral as required (3-wire connection with neutral), secure the device with screws, and verify the alignment with the 71 mm x 71 mm cutout. Follow the Installation Instructions for correct wiring sequencing and safety.
The unit operates at 230 V, 50 Hz with two independent outputs and two inputs, rated up to 8 A per channel. It supports a range of loads including LED retrofit, fluorescent, incandescent, and halogen lamps, with a maximum switching power depending on load type. No-load power loss is 0.3 W, aiding energy efficiency in continuous operation.
Yes. The product range includes flexTronics, flexTronics Wireless, free@home Wireless, and free@home. It is designed to work with ABB Comfort switch flex control elements and Watchdog sensors, offering streamlined integration and scalable automation within ABB ecosystems.
The relay insert is RoHS and REACH compliant and falls under WEEE regulations. It provides an Environmental Product Declaration (EPD) and CMRT documentation, supporting responsible material use, safe disposal, and regulatory transparency for industrial and commercial installations.
The 2CKA reduces wiring complexity with screw terminals and a compact 2-gang footprint, shortening installation time. Its low standby power (0.3 W) lowers energy costs over time, while compatibility with extension inserts and ABB control elements minimizes spare parts and field adjustments, delivering predictable performance and improved total cost of ownership.
