MTN648493 Schneider Electric KNX Switch Actuator REG-K/12x230/16 12-Channel 16A Manual Mode DIN-Rail

A twelve-channel switch actuator is a distribution strategy in its own right. The Schneider Electric MTN648493, officially Switch actuator REG-K/12x230/16 with manual mode, light grey, groups twelve independent 230 V make contacts rated at 16 A into a single 12-module DIN-rail device of approximately 216 mm width. For a building electrician, one of these modules can replace an entire row of smaller actuators and bring order to the most demanding lighting distribution boards.

Because Schneider Electric documents the REG-K/12x230/16 platform as connectable with different phases, panel builders can distribute the twelve circuits across L1, L2 and L3 in a three-phase board, balancing the load and reducing the risk of an overloaded neutral or phase. This phase-flexible wiring is one of the reasons large contractors choose the 12-channel format over a stack of smaller units.

Technical Specifications

Current handling follows the classic REG-K philosophy: 16 A per contact with comfortable margins for inrush, and a contact design rated for many thousands of operations. Screw terminals accept solid conductors reliably, the bus connects through a standard bus terminal without any data rail, and a green LED signals that the application is loaded. The light-grey housing and modular 18 mm pitch keep the device consistent with the rest of the installation, and IP20 protection suits clean indoor distribution boards.

Advanced Functionality

The ETS application is the same mature toolset that made the REG-K family a specification staple: ON/OFF control with status and feedback, staircase lighting functions, delays, scenes, logic operations, central commands and blocking or priority control, with behaviour on bus voltage failure and recovery defined output by output. Manual mode, as the type code promises, is built in: every one of the twelve outputs can be operated by hand directly on the device, whether the bus is live, commissioning, or entirely offline. In practice that means a technician can switch any circuit in seconds during an emergency without hunting for a controller.

For independent-site buyers the MTN648493 sits in the most requested niche of the Schneider KNX actuator catalogue: genuine original modules for large-scale panel building and for extending or repairing existing Merten/Schneider KNX plants. Because the platform is standard and current, ETS applications, datasheets and replacement availability are all well established.
