Siemens Reyrolle 7XG225 3RMLG Test Block

7XG225 3RMLG Test Block is a flexible and high performance test block system with a focus on operator safety. Suitable for application on a wide range of protection relay panels.

• Finger safe test sockets
• Automatic CT shorting
• 14 or 28 independent test groups

Features

• The 14-way test blocks occupy Epsilon size E2 cases, while the 28-way blocks utilize E4 cases.
• Each model includes CT shorting.
• Shorting takes place in the test block, not the test plug.
• Uses a three stage isolation process.
• Test plugs feature 4mm shrouded test points.

Functions

• 14 way test blocks with 5 connection options.
• 28 way test blocks with 5 connection options
• All 14 way blocks use the same 14 way test plug
• All 28 way blocks use the same 28 way test plug

Applications:

Test blocks enable technicians to isolate protection relays quickly and safely so they can inject test signals and verify system performance.There are a number of advantages in performing injection tests at the protection relay panel:

• Reduction in down time of the equipment under test
• Testing does not cause disturbance to wiring, terminals or equipment settings
• Technicians can isolate the existing auxiliary supply to the equipment under test.

The 3RMLG Test Block system provides a general-purpose isolation and test signal injection point. We employ finger-safe sockets to improve operator safety and accommodate 4mm shrouded banana plugs. Technicians only remove equipment for servicing if they detect problems or perform routine maintenance. If you require more than 14 test circuits, refer to the 3RMLG models that provide 28 test circuits.
