Switched Interlocked Industrial Sockets | CEE Switch Sockets with Mechanical Interlock

A switched interlocked socket combines an IEC 60309 socket outlet with a built-in rotary load-break switch and mechanical interlock mechanism in a single enclosure. The interlock physically prevents plug insertion or removal when the switch is ON, and prevents the switch from being turned ON until a plug is fully inserted. This ensures that electrical connections are never made or broken under load. KRIPAL UKS switched interlocked sockets are available from 16A to 125A.

The operating sequence is: insert the plug with switch in OFF position, rotate switch handle to ON to energize the circuit, rotate back to OFF to de-energize, then remove the plug. The interlock mechanism physically blocks the switch handle from moving to ON without a plug present, and blocks the plug latch from releasing while the switch is ON. This enforced sequence cannot be bypassed without deliberate mechanical tampering.

A switched interlocked socket integrates the switch, interlock mechanism and socket in one factory-assembled unit, saving installation time and wall space compared to wiring a separate switch-disconnector to a standard socket. The integrated interlock provides assured safety sequencing, whereas a separately installed switch and socket require the operator to follow correct procedures without mechanical enforcement.

The integrated rotary switch is rated AC-23 for switching motor loads and other inductive circuits. Switch current ratings of 16A, 32A, 63A and 125A match the socket rating. The switch uses a snap-action contact mechanism ensuring rapid make and break independent of how quickly or slowly the operator turns the handle, which extends contact life and provides consistent arc interruption.

Yes. KRIPAL IP67 switched interlocked sockets are suitable for outdoor installations subject to rain, dust and temporary immersion. The switch handle operates through a sealed shaft gland maintaining the IP67 enclosure rating. Stainless steel enclosure versions are available for food processing, marine and other corrosive environments requiring both IP67 sealing and material corrosion resistance.

Yes. Panel mount versions are available where the socket and interlock mechanism mount through a panel cutout with the switch handle accessible from the front face. This configuration suits distribution board integration, machinery control panels and generator enclosures where the operator needs front-panel switch access with the socket connection on the panel exterior.

KRIPAL switched interlocked sockets carry CE marking with compliance to IEC 60309-1 and IEC 60309-2 for the socket component, and IEC 60947-3 for the integrated switch-disconnector. The interlock mechanism is tested to verify correct operation over the full mechanical endurance cycle count. Complete test documentation supports installation compliance and safety audit requirements.

Yes. KRIPAL provides private label switched interlocked sockets with your part numbers and ratings marked on the enclosure. Custom enclosure configurations, specific cable entry positions and branded installation documentation are available for OEM and project programs.
