Why Choose the TE Connectivity CPT-2 Voltage Socket Protection Lid?
The TE Connectivity CPT-2 1SNA166577R2000 is a protecting lid with electrical continuity for ESSAILEC voltage sockets, designed to protect test connections during normal operation while maintaining the required electrical circuit continuity. Part of the established TE Connectivity ENTRELEC ESSAILEC test block range, it is intended for measurement, protection and testing installations used in industrial electrical systems.
During normal operation, the CPT-2 helps protect compatible voltage test sockets against dust and unauthorised access. Unlike a standard protective lid, this version incorporates electrical continuity through internal pins and a linking bar, making it suitable for ESSAILEC socket configurations with opened contacts where continuity must be maintained when the test plug is not connected.
The CPT-2 has a grey finish, provides IP40 protection when correctly fitted and weighs approximately 40 g. Its compact ESSAILEC-compatible construction provides a straightforward way to protect voltage test interfaces while supporting safe and efficient operation of electrical measurement and protection circuits.
Key Advantages
- Purpose-designed protecting lid for ESSAILEC voltage sockets.

Reliable Protection for ESSAILEC Test Connections
ESSAILEC test blocks are designed to simplify electrical testing, measurement, monitoring and maintenance in secondary current and voltage circuits. Protective lids help keep socket interfaces covered during normal service, reducing exposure to dust and discouraging unauthorised access to test connections.
For opened-contact voltage socket configurations, electrical continuity must be preserved while the test connection is not in use. The CPT-2 addresses this requirement with integrated internal pins and a linking bar, combining physical socket protection with the continuity function required by the compatible ESSAILEC arrangement.
Typical Applications
- ESSAILEC voltage test socket assemblies.
- Electrical measurement and metering circuits.
- Protection relay testing installations.
- Secondary circuits associated with voltage transformers and sensors.
- Industrial switchboards and control panels.
- Power distribution and electrical testing systems.
