Safety and convenience in test interfaces

The LTB is a test block with extended rear terminals that allows for easy and safe disconnection of IEDs (protective relays, fault recorders, revenue meters, etc.) from the system side of the power grid. The LTB typically works in conjunction with the LTP test plug, which features an integrated leverage mechanism to assist with its insertion into the LTB.

The sophisticated mechanical design of the LTP ensures a seamless plug-in process for the test plug. This enables a quick disconnection of a large number of poles with just a few simple movements.
