Why Choose the TE Connectivity FIP-2/4-1 ESSAILEC 2 × 4-Pole Plug?
The TE Connectivity FIP-2/4-1 1SNA166559R0600 is a 2 × 4-pole test plug from the established ENTRELEC ESSAILEC test block range. Designed for electrical measurement, protection and test circuits, this blue plug provides a removable multicircuit interface for compatible ESSAILEC sockets and allows engineers to connect test equipment without unnecessarily disturbing permanent panel wiring.
The FIP-2/4-1 features a short-cover 8-pole configuration arranged as two rows of four poles. It is supplied with 8 locking pins and 2 coding pins, helping provide secure mechanical retention and correct positioning within a compatible ESSAILEC installation. BRE-T contact pins are selected according to the conductor requirements of the application and are ordered separately.
With a compact body measuring approximately 63 × 44 × 115 mm and a weight of approximately 91 g, the FIP-2/4-1 provides a practical test connection for switchgear, metering panels, substations and industrial protection systems. The ESSAILEC system is designed for secondary current and voltage circuits where controlled access for commissioning, measurement and maintenance is essential.
