Why Choose the TE Connectivity CPT-5 ESSAILEC Voltage Socket Protective Cover?

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.

Key Advantages

  • Purpose-designed protective cover for ESSAILEC voltage sockets.
  • Helps protect compatible voltage test interfaces when not in use.
  • Part of the proven TE Connectivity / ENTRELEC ESSAILEC system.
  • Standard cover configuration without electrical continuity.
  • Compatible with selected ESSAILEC voltage sockets and mounting arrangements.
  • Compact accessory for protection, metering and measurement installations.

Key Features

  • TE Connectivity / ENTRELEC ESSAILEC series.
  • CPT-5 model designation.
  • Designed as a cover for voltage sockets.
  • Version without electrical continuity.
  • Compatible with selected ESSAILEC voltage-range sockets.
  • Suitable for protection, metering and instrumentation test systems.
  • Approximately 66 g net weight.
  • Genuine ESSAILEC test block accessory.

Reliable Protection for ESSAILEC Voltage Test Interfaces

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.

Typical Applications

  • ESSAILEC voltage test socket protection.
  • Voltage transformer secondary circuit installations.
  • Protection relay and control panels.
  • Electrical metering and measurement systems.
  • Substation protection equipment.
  • Switchgear and distribution assemblies.
  • Industrial instrumentation and testing systems.
