MS4M range - Test Blocks & Plugs
The MS4M300 Test Link Panel has been designed as a general-purpose isolation & test signal injection point. Standard 4mm diameter sockets are employed so that common banana plugs may be used to short CT inputs & connect test equipment.
Test links are an important accessory for protection, metering & control panels. They enable test technicians to quickly & safely isolate protection relays so that test signals may be injected & system performance verified.
MS4M300-A TEST BLOCK (Isolating Plug not fitted)
- The MS4M300 Test Block has been designed as a general-purpose isolation & test signal injection point with 14 independent circuits.
MS4M300-B TEST BLOCK (Includes Isolating Plug)
- The MS4M300 Test Block has been designed as a general-purpose isolation & test signal injection point with 14 independent circuits.
MS4M320 TEST PLUG (For 4M300-A & B)
- The MS4M320 Test Plug employs colour coded 'finger safe' 4mm diameter sockets are employed so that either shrouded or standard 4mm banana plugs may be used to short CT inputs & connect test equipment.
