The TE Connectivity TC-E-VA (1SNA166747R0200) is an ESSAILEC short-circuited voltage test socket designed for electrical protection, metering, measurement and voltage transformer circuits. Part of the TE Connectivity ENTRELEC ESSAILEC range, it provides a dedicated test interface for commissioning, monitoring and maintenance in industrial and utility electrical installations.
The TC-E-VA features flush mounting and ring-tongue connections, with short-circuited contacts designed around the ESSAILEC make-before-break test principle. Its grey polycarbonate body identifies it as part of the voltage range, while silver-plated conductive components provide a durable electrical connection for repeated professional testing operations.
Rated at 400 V and 8 A, the TC-E-VA supports cable sizes from 0.34–10 mm² and measures approximately 74 × 50 × 57 mm. It is compatible with accessories including the CPT-1 lid, FI-2/4-DIA4 universal plug and selected pre-wired ESSAILEC plugs, providing a flexible solution for protection panels, switchgear, substations and metering systems.
ESSAILEC voltage test blocks provide a dedicated interface between permanently installed measurement or protection circuits and compatible test equipment. Their modular design allows engineers to perform commissioning, voltage measurement, monitoring and maintenance through an organised connection point while reducing the need to disturb permanent field wiring.
The TC-E-VA combines short-circuited contacts with flush mounting and secure ring-tongue termination. Together with compatible ESSAILEC plugs and accessories, this provides a practical testing solution for voltage transformer secondary circuits, protection relays and metering installations where repeatable and dependable test access is required.
