£49.19
The TE Connectivity CPT-5 1SNA166930R2600 is a dedicated protective cover for ESSAILEC voltage sockets, designed to protect compatible test interfaces when they are not in use. Part of the established TE Connectivity / ENTRELEC ESSAILEC measuring and testing range, the CPT-5 provides a purpose-designed protective accessory for voltage measurement, metering and protection installations.
Unlike the CPT-4 version, which incorporates electrical continuity, the CPT-5 is the standard cover without electrical continuity. It is intended for compatible ESSAILEC voltage sockets and can be used with base-mounted configurations, with specific compatibility restrictions applying to certain socket and mounting combinations.
The CPT-5 measures approximately 128 mm high × 54 mm wide × 55.5 mm deep and has a net weight of approximately 66 g. Its robust, compact construction makes it suitable for protection relay panels, switchgear, substations and industrial metering installations using the modular ESSAILEC test system.
ESSAILEC test blocks provide dedicated interfaces for voltage measurement, monitoring, injection, commissioning and maintenance operations involving voltage transformers, meters and protection relays. Protective accessories such as the CPT-5 help keep compatible socket interfaces covered during normal operation when test equipment is not connected.
The CPT-5 is the standard ESSAILEC voltage socket cover, while the CPT-4 is the corresponding cover incorporating electrical continuity. For TO-DS-VL, TC-DS-VL and TF-DS-VL sockets, CPT-5 compatibility applies specifically to the base-mounting configuration, making correct socket and mounting selection important when specifying the accessory.

The CPT-5 is a protective cover for compatible ENTRELEC ESSAILEC voltage sockets, designed to cover the test interface when it is not being used.
No. The CPT-5 is the standard cover without electrical continuity. The ESSAILEC CPT-4 is the corresponding cover designed with electrical continuity.
The CPT-5 is intended for selected ESSAILEC voltage sockets. For the TO-DS-VL, TC-DS-VL and TF-DS-VL socket types, manufacturer selection guidance specifies compatibility with the CPT-5 in the base-mounting configuration.
The CPT-5 measures approximately 128 mm high × 54 mm wide × 55.5 mm deep.
It is typically used with compatible ESSAILEC voltage test sockets installed in protection relay panels, switchgear, substations, electrical metering systems and industrial instrumentation assemblies.
TE Connectivity’s ENTRELEC ESSAILEC accessories provide purpose-designed protection and connection solutions for electrical test interfaces, helping maintain organised and serviceable voltage measurement, metering and protection installations.
