TE Connectivity ESSAILEC RJ45 test for digital switchgear

TE Connectivity’s ESSAILEC RJ45, part of the ESSAILEC test blocks range, is designed to fit electricity utilities’ requirements for safe and reliable testing. Test operations can be made without opening the switchgear panel door and without changing the wiring.

It addresses the test and measurement operations on current or voltage sensors and digital relays.

The product is a compact unit comprising a socket and a test plug, and it uses a ‘plug and play’ concept. The ESSAILEC socket is installed in the circuit and wired to the device (protection relay in switchboard or meters) to allow test operations during its installation or servicing. The plug will be connected to the test set during test operation to allow sensor measurement or signal injection into the relay.

The combination of the RJ45 connection and the ‘make before break’ principle makes testing switchgear protection relays quick and easy. The circuit is automatically disconnected when the plug is inserted and reconnects automatically when the plug is removed. The test block’s shielded body warranties EMC compliance and signal protection.
