The TE Connectivity 1SNA167692R2500, designated FCB-2, is a red bayonet security test plug designed for use with compatible ESSAILEC test block systems. It provides a secure and convenient connection point for electrical testing, measurement and commissioning within protection, metering and industrial control circuits.
The FCB-2 uses a quarter-turn bayonet connection, providing a positive connection to compatible test interfaces during diagnostic and maintenance procedures. Its red colour coding enables clear visual differentiation from the black FCB-1 version, helping technicians organise test connections and reduce the risk of connection errors.
As part of the TE Connectivity / Entrelec ESSAILEC range, the 1SNA167692R2500 supports test procedures associated with current and voltage measurement, monitoring, injection testing and maintenance of meters and protection relays. Its compact construction and approximately 7 g weight make it a practical accessory for professional test and protection-panel installations.
ESSAILEC test blocks are designed to simplify testing within the secondary circuits of current and voltage transformers, sensors, meters and protection relays. Dedicated test accessories allow technicians to perform measurements, monitoring and injection procedures while maintaining an organised and controlled electrical interface.
The FCB-2 provides a secure bayonet-style connection for these testing operations. Its red identification and quarter-turn design make it particularly useful where test connections must be established quickly and reliably during commissioning, scheduled maintenance and fault diagnosis.
