Schneider KNX Switch Actuator REG-K/12×230/16 with Manual Mode and Current Detection (MTN648495)

Description

Introduction

The Schneider Electric MTN648495 is a high-performance REG-K 12-channel KNX switch actuator engineered for independent switching of electrical loads in KNX home and building automation systems. Designed to occupy 12 modules of 18 mm on standard DIN rail installations, this light grey device operates across a wide rated operational voltage range of 100…240 V AC at 50…60 Hz with a switching current rating of 16 A per channel. This device is part of our KNX Actuators range.

Equipped with integrated current detection and manual operating mode, the MTN648495 allows system integrators and electrical installers to implement centralized control, optimize energy usage, and maintain flexible operational oversight. Its modular design supports connection with different phases across channels, providing a versatile solution for modern building management and commercial or residential KNX automation projects.
