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
| Model | Part Number | Channels | DIN Width |
|---|---|---|---|
| Switch Actuator REG-K/4*230/16 | MTN647593 | 4 channels | ~4 TE (72 mm) |
| Switch Actuator REG-K/8*230/16 | MTN647893 | 8 channels | ~8 TE (144 mm) |
| Switch Actuator REG-K/12*230/16 | MTN648493 | 12 channels | ~12 TE (216 mm) |
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.
