Description
FEATURES:
- Offer easy access for on-site testing of Ammeters, KWH Meters, Demand Indicators, Trivector Meters, Relays and Instrument
Transformers without disconnecting from load and avoid C.T open circuit problems - Connections for testing can be easily made
- Test Terminal Blocks are an important element of the metering solution
- Designed for projection mounting with either front or back connection possibilities, designated with FC or BC
- For 3-phase, 3-wire or 3-phase 4-wire application for up to 50A continuous rating at 600V and generally conform to IEC60947-7-1
- The most popular Test Terminal Block has 13 terminals in total of which 9 are current terminals and 4 are voltage terminals
- The current terminals are separated into groups of 3 with inter-terminal shorting links for short-circuiting of the CT terminals and testing
- The base 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 flash-overs
- In addition, a bakelite shield is provided in front to avoid flash-over or shorting at cable entries
- A moulded shroud is provided for safety against the voltage terminals
- For viewing the inside connections without removing the cover, thus saving time of the operator, a transparent, sturdy and flame
retardant (UL94V0) poly-carbonate top cover is provided - Optionally, the top cover is offered in bakelite
- The top cover is secured in place by knurled knobs and a sealing arrangement is provided to prevent unauthorised access
- The Test Terminal Block can be fitted to any panel by means of 4 holes provided on the base
- All terminals, shorting links, screws, nuts, etc. used in the electrical connections are of bright nickel-plated brass to prevent corrosion and to provide high connectivity
- The screws are provided with rounded edges to prevent any damage to cable strands. Each terminal has 6mm (dia) hole for cable entry and two M5 screws secure the cables
- For the back connected Test Terminal Blocks, colour coded sleeves of brown, black, grey and blue (neutral) are provided to indicate
