Application
For mounting on switchboard panels for use in conjunction with proper test equipment to facilitate the testing of AC instruments, meters and relays
Features
Type PK-2 test blocks are essentially 4-pole and 6-pole jacks, provided with moulded phenolic covers that have internal plug contacts, which make a through connection when the cover is in place.
The contacts in the block are of the line - pressure type and provide positive contact with minimum contact resistance. For current circuits, auxiliary contacts are used which automatically short
circuit the current transformer when the cover or plug is removed.
Rountine testing can be accomplished simply by removing and substituting the properly connected test plug; Normal connections can be restored, by replacing the cover
Contact rating is 250 Volts, 10 Amperes continuously.
