TE Connectivity CPP-2 1SNA166645R0400 is a blue ESSAILEC protecting lid with electrical continuity designed to protect compatible polarity sockets while maintaining the required electrical circuit connection.
£44.02
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.
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.
