13 WAY 3PH 4 WIRE FRONT CONNECTION with PC TRANSPARENT COVER

These Test Terminals Blocks offer easy access for on-site testing of Ammeters, kWH Meters, Maximum Demand Indicators, Trivector Meters, Relays and Instrument Transformers, without disconnecting them from the load. This thus avoids C.T. open circuit problems and facilitates easy Connections for testing instruments.. The Test Terminal Block therefore becomes an important element of the Metering Solution. The Test Terminals Blocks are designed for projection mounting with either front or back connection possibilities, designated as FC or BC. The Test Terminal Blocks are suitable for 3 phase 4 wire application for up to 50 A , 600 V, continuous rating , and generally conform to IEC 60947-7-1.

The most popular 13 Way TTB has 13 Terminals. The 9 current terminals are separated from the 4 voltage terminals for testing, with inter-terminal shorting links for short-circuiting of the CT terminals. Voltage section has facilitates injecting voltage from external source by using Banana plugs.
