Schneider Electric KNX Switch Actuators MTN647593 / MTN647893 / MTN648493— The Smart Choice for Building Automation

Whether you're designing a smart home, an office automation system, or a large commercial building, Schneider Electric's KNX Switch Actuator REG-K series delivers the reliability, flexibility, and scalability your project demands. The MTN647593 (4-channel), MTN647893 (8-channel), and MTN648493 (12-channel) are engineered for professional KNX installations — giving you full control over your electrical loads from a single DIN rail device.

KNX switch actuators are DIN rail-mounted modules that receive switching commands from the KNX bus and physically switch connected electrical loads on or off. Schneider Electric's REG-K series integrates a built-in bus coupling unit, so no separate coupler is required — simplifying installation and reducing panel space.

All three models share a common design philosophy:

• Rated voltage: AC 230 V (50/60 Hz)
• Switching current: 16 A per channel (AC1)
• Manual override on every output — ideal for commissioning and maintenance
• DIN rail (TH35) mounting per EN 60715
• KNX certified — compatible with ETS software and all KNX-compliant devices

Each model supports switching of:

• Incandescent & halogen lamps up to 3600 W / 2500 W
• Fluorescent & LED lighting up to 2500 VA
• Capacitive loads up to 200 µF at 230 V AC
• DC loads: 16 A at 24 V DC

• Independent channel control — Every output is individually addressable via KNX, enabling granular scene control, time scheduling, and logic functions through ETS.
• Manual operation on every output — A physical switch on each channel allows direct switching without bus communication. This is critical during testing, fault diagnosis, and step-by-step commissioning.
• High switching capacity — At 16 A per contact (AC1), these actuators handle demanding loads including motor circuits, high-power lighting rigs, and socket circuits.
• Integrated bus coupler — No additional KNX coupler needed. The device connects directly to the KNX bus terminal, saving space and simplifying wiring.
• Scalable for any project size — From a 4-channel unit for a residential apartment to a 12-channel module for a floor distribution board in a commercial building, Schneider's REG-K series scales cleanly within the same product family.

• Residential smart homes — Automate lighting in living rooms, bedrooms, hallways, and outdoor areas with scene control and presence-based logic.
• Office buildings — Central "All Off" switching at end of business day, scheduled lighting zones, and occupancy-based control.
• Hotels & hospitality — Guest room load control, corridor lighting management, and energy-saving absence modes.
• Retail & commercial spaces — Display lighting control, circuit enable/disable scheduling, and centralized load management.
• Industrial & technical rooms — Reliable switching of HVAC ventilation circuits, pump controls, and auxiliary equipment.
• Building management systems (BMS) — Deep integration into EcoStruxure and third-party BMS platforms via KNX gateway.

Schneider Electric is a globally trusted name in energy management and automation. The MTN647593 / MTN647893 / MTN648493 are part of the Merten system, renowned for build quality, long service life, and seamless KNX ecosystem integration. With full ETS compatibility, these devices support:
