Why Choose the TE Connectivity TC-E-C5A-ICE-2.2 ESSAILEC Voltage Test Socket?

The TE Connectivity TC-E-C5A-ICE-2.2 1SNA166681R2100 is a dedicated ESSAILEC voltage-transformer test socket designed for safe and efficient testing, measurement and maintenance of secondary voltage circuits. Part of the established TE Connectivity ENTRELEC ESSAILEC range, this ICE-specific socket provides a controlled plug-in interface for test equipment used in switchgear, metering and protection installations.

The TC-E-C5A-ICE-2.2 is designed for flush front-panel mounting and uses Faston connection technology for practical installation within electrical assemblies. Its 2.2 coding configuration helps prevent incorrect connection between different circuits, while the ESSAILEC contact arrangement provides a controlled interface between the permanently wired voltage-transformer circuit and compatible test plugs.

Supplied with a protective cover, the socket provides IP20 protection without the cover and IP40 protection when the cover is fitted. The ESSAILEC system is engineered to simplify operations including voltage measurement, monitoring, signal injection, commissioning and the repair or replacement of meters and protection relays connected to transformer secondary circuits.

Reliable Test Access for Voltage Transformer Circuits

ESSAILEC test blocks provide a dedicated interface for accessing secondary transformer and sensor circuits during electrical testing. They allow engineers to perform voltage measurements, monitoring, signal injection, commissioning and maintenance through a plug-and-socket connection, helping avoid repeated disconnection of permanent panel wiring.

The TC-E-C5A-ICE-2.2 combines front-panel accessibility, Faston wiring and coded mating protection in an ICE-specific configuration. When used with the appropriate ESSAILEC test plug, it provides a repeatable connection point for testing meters, protection relays and associated voltage circuits in industrial power and utility applications.

Typical Applications

• Voltage-transformer secondary circuits.
• Electrical metering and measurement panels.
• Protection relay testing and commissioning.
• Substation control and protection equipment.
• Industrial switchgear and distribution assemblies.
• Meter and protection-relay replacement or maintenance.
• Electrical monitoring and signal-injection systems.
