1sna166645r0400 – cpp-2

Why Choose the TE Connectivity CPP-2 ESSAILEC Polarity Socket Protection Lid?

The TE Connectivity CPP-2 1SNA166645R0400 is a purpose-designed protecting lid with electrical continuity for ESSAILEC polarity sockets. Part of the established TE Connectivity ENTRELEC ESSAILEC measuring and testing range, it protects compatible polarity test connections during normal operation while maintaining the required electrical continuity.

The CPP-2 is specifically identified as the blue protecting lid for polarity sockets with electrical continuity. Its integrated continuity arrangement makes it suitable for ESSAILEC applications where the circuit connection must remain established when the test interface is covered and no test plug is connected.

With compact dimensions of approximately 73 × 49 × 30 mm (H × W × D) and a net weight of approximately 40 g, the CPP-2 provides a practical protective accessory for measurement, monitoring and protection circuits. Its dedicated ESSAILEC construction ensures compatibility with the associated polarity socket system used in industrial switchboards, electrical panels and power-distribution installations.

Key Advantages

• Purpose-designed protecting lid for ESSAILEC polarity sockets.
• Provides electrical continuity when fitted to the compatible socket.
• Helps protect the test interface during normal equipment operation.
• Blue colour coding provides clear identification within the ESSAILEC system.
• Compact and lightweight construction for straightforward handling.
• Designed specifically for the proven TE Connectivity ENTRELEC ESSAILEC test system.

Reliable Protection for ESSAILEC Polarity Connections

ESSAILEC measuring and testing blocks provide dedicated interfaces for current and voltage measurement, monitoring, injection, maintenance and protection-relay testing in secondary electrical circuits. Protective lids cover compatible socket interfaces during normal service, helping maintain an organised and protected test installation.

The CPP-2 combines physical socket protection with an electrical continuity function. This makes it particularly suitable for compatible polarity circuits where continuity needs to be maintained when test equipment is disconnected and the protective lid is installed.

Typical Applications

• ESSAILEC polarity test socket assemblies.
• Electrical measurement and metering circuits.
• Protection relay testing installations.
• Secondary circuits for electrical transformers and sensors.
• Industrial switchboards and control panels.
• Power distribution and substation equipment.
