Schneider MTN648493 KNX Switch Actuator REG-K/12×230/16 with Manual Mode

Description

Introduction

The Schneider MTN648493 KNX Switch Actuator REG-K/12×230/16 provides flexible and energy-efficient centralized control for intelligent building automation systems. Engineered for DIN rail installation across 12 module widths (18 mm each), this light grey actuator enables independent switching of up to 12 individual electrical loads operating at 230V AC with a nominal current rating of 16A per channel. This device is part of our KNX system components range.

Designed for commercial projects and advanced residential systems, the MTN648493 optimizes overall power usage and streamlines installation. Featuring integrated manual switches directly on the front panel, system integrators and installers can execute direct physical switching and operational testing per channel independently of bus communication.

Key Features

• 12 independent switching contacts rated at 16A at 230V AC.
• Integrated manual control buttons for direct physical local operation.
• Modular REG-K enclosure occupying 12 x 18 mm DIN rail spaces.
• Supports multi-phase connectivity across distinct switching channels.
• Compatible with load types including Incandescent (<= 3600W), Halogen (<= 2500W), Fluorescent (<= 2500VA), and Capacitive (16A, 200 µF).
• Operates across standard mains frequencies of 50…60 Hz.
• IP20 protection rating with angled device presentation in light grey.

Benefits

• Centralized load switching minimizes energy waste and delivers measurable operational cost savings across building installations.
• Twelve independent 16A channels support multi-phase power connections, delivering exceptional versatility for panel design.
• Integrated manual override switches enable direct hardware testing and emergency switching without active KNX bus control.
• Standardized 12-module DIN rail mounting form factor allows clean, space-efficient integration within electrical switchboards.
• Handles diverse load profiles reliably, including incandescent, halogen, fluorescent, and high capacitive load switching.
• Environmentally conscious design featuring sustainable packaging with at least 70% recycled cardboard content.

Installation Notes

• Snap-mount the actuator onto a standard 35 mm DIN rail inside an IP20-rated enclosure or switchboard panel.
• Verify that load current draw on each output contact does not exceed the maximum rated 16A prior to power application.
• Multi-phase connections are permitted across different channels; maintain proper phase segregation and cabinet wiring layout.
• Use the front-panel manual switches during initial setup to confirm correct load wiring prior to ETS parameter configuration.
