The Gewiss GW66449 is a compact interlocked industrial switched socket-outlet from the Gewiss IB Range, designed for safe and reliable power distribution in industrial and commercial installations. Featuring a 3P+E configuration, 16 A rated current and 200–250 V AC rated voltage, it is designed for specialised nominal 230 V three-phase systems without a neutral connection.
The GW66449 incorporates a mechanical interlock that controls the connection, switching and disconnection sequence. A compatible plug can only be connected or disconnected when the switch is in the open position, while the switch can only be closed when the plug is correctly inserted. This helps ensure connections and disconnections take place off-load, improving operational safety in professional installations.
With IP55 ingress protection and IK08 mechanical impact resistance, the GW66449 provides robust protection for demanding environments. The blue socket features a 9h earth reference position, operates at 50/60 Hz and is supplied with a back-mounting box, providing a complete compact solution for surface-mounted installations.
Interlocked socket-outlets improve electrical safety by controlling the sequence in which equipment can be connected, energised and disconnected. On the Gewiss GW66449, the mechanical interlock allows plug insertion and removal only when the control switch is open and permits the switch to close only when the plug has been correctly inserted. This arrangement helps prevent connection or disconnection under load.
The combination of 16 A capacity, 200–250 V AC operation, 3P+E configuration, 9h reference position, IP55 protection and IK08 impact resistance makes the GW66449 particularly suitable for specialised 230 V three-phase equipment without neutral. Its compact COMBIBLOC design and included back-mounting box provide a convenient solution for professional surface-mounted industrial power distribution.
