India 10 Way TTB Test Terminal Blocks, 600 V

Product Description

These Test 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, thus avoiding C.T. open circuit problems. Connections for testing are made easy,the Test Blocks thus becoming an important element of the Metering Solution.

The Test Blocks are designed for projection mounting with front connection possibilities, designated as FC. The Test Blocks are suitable for 3 phase 3 wire , and 3 phase with Neutral supply application for up to 30 A ,continuous rating at 450 V and generally conform to IEC 60947-7-1.

The most popular 10 Way TTB has 10 Terminals in total, of which 6 are current , 3 are voltage ,and 1 is a Neutral terminal. . The current terminals are separated into groups of 2 with inter-terminal shorting links for testing and short-circuiting of the CT terminals.

The base of the Test Block is made of excellent quality electrical grade black bakelite moulding powder. The base moulding is provided with integrally moulded barriers between the terminals for complete protection against flashovers.

The test terminal blocks are used for easy access during on site testing of Ammeters, KWH Meters, Maximum Demand Indicators, Trivector Meters, Relays and Instrument Transformers without disconnecting from load and avoid CT open circuit problems. Connections for testing can be easily made. 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 with FC or BC. The Test Terminal Blocks are for 3 phase, 3 wire or 3 phase 4 wire application for up to 50 A continuous rating at 600 V.
