PCE Electric CEE Switched Interlocked Sockets for Industrial Power Distribution
CEE switched interlocked sockets provide a critical safety and control solution for industrial power distribution in professional AV, theatre, and production environments. These units integrate a CEE socket with a local ON/OFF switch, ensuring that power cannot be connected or disconnected under load. This mechanical interlock mechanism prevents accidental disconnection of live circuits, protecting both equipment and personnel from arcs, sparks, and potential injury. Designed for demanding applications, these sockets are available in various pole configurations (3p, 4p, 5p) and current ratings (16A, 32A, 63A), accommodating a wide range of voltage requirements. Key features include durable PC/ABS housing, nickel-plated brass contacts for reliable conductivity, and screw terminals for secure wiring. Many models offer high ingress protection ratings, such as IP44/IP54 and IP66/IP67, making them suitable for both indoor and harsh outdoor conditions where dust, splashing water, or even temporary immersion might be a concern. Installation flexibility is provided through wall-mounting designs with multiple cable entry options (top, bottom, or rear). The integrated DIN-rail switch, often a PCE-Merz ML0 or ML2-063, meets EN 60947-3 standards for AC22A switching capacity and 10kA short-circuit breaking capacity. Some advanced models also incorporate RCBOs (Residual Current Breaker with Overcurrent protection) for enhanced electrical safety, offering protection against both overcurrents and earth leakage faults, which is essential for temporary installations and live events.
