Why Choose the TE Connectivity FIP-2/4-2 1SNA166939R2300 ESSAILEC Test Plug?
The TE Connectivity FIP-2/4-2 1SNA166939R2300 is a professional 2 × 4-pole ESSAILEC test plug designed for testing, measurement and maintenance of secondary electrical circuits. Part of the established TE Connectivity ENTRELEC ESSAILEC series, it provides a removable interface between compatible ESSAILEC sockets and external test equipment used for commissioning, diagnostics and servicing.
The FIP-2/4-2 features a blue body and long-cover 2 × 4-pole configuration. It is supplied with 2 COP-FI-1 coding pins and 8 locking pins, helping provide correct positioning and secure mechanical engagement with compatible ESSAILEC sockets. The required BRE contact pins are selected and ordered separately, allowing the plug to be configured for the conductor and test-lead requirements of the installation.
Weighing approximately 105 g, the 1SNA166939R2300 is compatible with a broad selection of ESSAILEC voltage-circuit sockets, including TC, TO, PC and PO variants. Its multi-pole architecture allows several test connections to be grouped into one compact plug, making it particularly useful for switchboards, metering installations, protection panels and substation secondary circuits.

Reliable Multi-Circuit Testing for Measurement and Protection Systems
ESSAILEC test blocks provide a modular method for carrying out current and voltage measurements, monitoring, test-signal injection and maintenance of meters and protection relays installed in transformer and sensor secondary circuits. By combining a fixed socket with a removable test plug, engineers can access the required circuits without repeatedly disconnecting permanent field wiring.
The FIP-2/4-2 provides a multi-pole interface for these procedures. Its locking and coding components support repeatable plug positioning, while separately selected BRE contacts allow the test assembly to be configured for the intended wiring arrangement. Compatible ESSAILEC systems can support simultaneous testing across multiple circuits, making the plug particularly useful for recurring commissioning and maintenance work.
Typical Applications
- Secondary voltage-circuit testing.
- Electrical metering and measurement systems.
- Protection relay commissioning and maintenance.
- Transformer secondary-circuit testing.
- Industrial switchboards and control panels.
- Substation protection and instrumentation systems.
- Power distribution monitoring installations.
