The TE Connectivity 1SNA167937R0000, also identified as FIC-2/4-DIA4, is a 2 × 4-pole ESSAILEC current plug and universal test adaptor designed for testing current-transformer secondary circuits. It is compatible with ESSAILEC current sockets and provides direct insertion points for standard insulated 4 mm test plugs, simplifying measurement, commissioning and maintenance operations.
As part of the established TE Connectivity / Entrelec ESSAILEC test block system, the FIC-2/4-DIA4 is engineered to provide quick and consistently reliable access to current circuits. Standard 4 mm test plugs can be inserted directly without additional accessories or tools, making the adaptor particularly convenient for technicians working with protection relays, meters and current-transformer installations.
The FIC-2/4-DIA4 is rated for a 15 A main circuit and 400 V, with a short-time withstand current of 200 A for 1 s. Its compact 44 × 63 × 55 mm construction and polycarbonate insulation provide a purpose-designed solution for professional testing in switchgear, substations and industrial electrical panels.
ESSAILEC test blocks are designed to provide controlled access to instrument-transformer secondary circuits during testing, measurement and maintenance. The FIC-2/4-DIA4 acts as a universal adaptor for ESSAILEC current sockets, allowing technicians to connect suitable test equipment efficiently without modifying permanent panel wiring.
Its direct 4 mm interfaces accept standard insulated test plugs, reducing the number of additional components needed during test operations. This makes the FIC-2/4-DIA4 particularly useful for commissioning and servicing protection relays, electrical meters and other equipment connected to current-transformer secondary circuits.
