Earth Terminal Block |

Installation example

|
|
It can be used to measure the earth resistance of electrical instruments and electrical circuits and can also be used as the earth terminal block. |
|
1) The earth resistance can be easily measured to open the movable bar.
2) The earth resistance can be easily measured to connect each pole of EA, EB and ED.
3) Terminal block, which has two movable bars and is configured at two stages (AT-200W) can be provided according to the condition.
4) The colored basement of the block such as green or black can be provided, if requested. |
Material |
Basement |

Earth Terminal Block for Back side wiring |

Example of installation:
Parallel grounding connection

|
|
It can be used to measure the earth resistance of electrical instruments and electrical circuits. |
|
1) It can be easy to make wiring for the instruments set at back connection.
2) The earth resistance can be easily measured to open the movable bar.
3) The earth resistance can be easily measured by connecting each pole of T1, T2 and T3. |
Material |
Insulation bushing: Bakelite
Others: same as Earth Terminal Block |
