MTN647593 Schneider KNX Switch Actuator REG-K 4-Channel 16A Manual Mode Light Grey DIN Rail 4 Module

The MTN647593 belongs to the SpaceLogic KNX switching-actuator portfolio engineered by Schneider Electric for reliable, high-density load commutation inside standard TH35 DIN distribution boards. This maintenance-friendly power rail element bridges KNX telegrams from the control layer into tangible 230 V AC switching actions for lighting, socket, and small-appliance circuits.

Factory-configured to accept commissioning data through the ETS toolchain, the unit integrates seamlessly with Schneider push-button interfaces, presence detectors, and scene controllers. Its compact mechanical profile, bistable-relay core, and clearly labeled front fascia reduce wiring effort and speed up panel assembly.

Built around flame-retardant engineering plastics and lead-free solder joints, the device complies with contemporary eco-design directives while sustaining continuous duty in commercial buildings, hotel guest wings, and residential smart-home distributions. Every output is protected against miswiring errors and supports group-address sharing for simultaneous multi-circuit control.

Its dependable 16 A bistable contacts comfortably drive high-inrush LED and fluorescent loads, while the manual mode ensures circuits remain operable even if the bus segment is temporarily interrupted for maintenance. Ideal for commercial buildings, educational facilities, hotel guest rooms, and smart-home distribution systems requiring reliable, maintenance-friendly switching solutions.
