Why Choose the TE Connectivity CPDE-1 ESSAILEC Protecting Lid?

The TE Connectivity CPDE-1 (1SNA166876R2400) is an ENTRELEC ESSAILEC protecting lid designed for polarity sockets within professional electrical test-block installations. It provides physical protection for the socket during normal operation, helping shield the test interface from dust and unauthorised access when test equipment is not connected.

The CPDE-1 is specifically identified for ESSAILEC polarity sockets and features an orange colour for clear visual identification within the test-block system. Unlike the CPDE-2 continuity version, the CPDE-1 is a standard protective lid without electrical continuity, making it suitable where continuity through the lid is not required.

When correctly installed, the CPDE-1 helps provide IP40 protection for the associated ESSAILEC test socket. With a weight of approximately 30 g and a compact purpose-designed format, it provides a simple replacement or installation accessory for protection, metering, commissioning and electrical testing systems.

Protecting ESSAILEC Test Interfaces During Normal Operation

ESSAILEC sockets provide dedicated interfaces for testing, measurement, commissioning and maintenance of secondary electrical circuits. During normal service, these interfaces may not have a test plug installed, so an appropriate lid helps protect the exposed socket from dust and unintended access while maintaining an organised panel installation.

The CPDE-1 is specifically designed for polarity sockets and provides a straightforward protective solution when electrical continuity through the lid is not required. For applications requiring continuity through the protective accessory, the ESSAILEC range provides the separate CPDE-2 lid with internal continuity components.

Typical Applications

• ESSAILEC polarity test sockets.
• Protection relay panels.
• Electrical energy metering systems.
• Measurement and monitoring installations.
• Substation protection and control panels.
• Switchgear test interfaces.
• Industrial electrical control panels.
• Utility power distribution systems.
