Test Blocks
In order to deliver improved value to our customers, we are changing the supplier of our 2RMLG01 Test Block.
For many years we have been supplying Siemens part number 7XG2220-1AA00-0AA0 “2RMLG01 Test Block - Vertical. Open 13-14 on cover removal”.
We are now stocking RMS part number 4M200-01 “Test Block 4M200 series. Vertical. 01=VVx open 13-14 on cover removal”.
The block(s) are identical (and interchangeable) in:
1) Function
2) Performance (and operation)
3) Cutout dimensions
4) Panel depth, height and width
5) Earth point
6) Terminal type position and numbers
7) Fit and wiring screw terminals etc.
The only difference is front markings and the style of the cover. The new cover is clear, and makes it more obvious that contacts 13-14 are opened on removal of the cover. The new cover has a more reliable thread compared to the bayonet used in the older block. Unlike the old block, we can also get spares of the new cover if needed.
