4 Way PK2 BC Test Blocks

facilitate the testing of AC instruments, meters and relays.

Technical Features

Type TTB 4W PK2 test blocks are 4-pole blocks, provided with moulded bakelite base and covers that have an arrangement of internal plug contacts, which make a through positive connection when the cover is in place. The contacts in the blocks are of the line pressure type and provide positive contact with minimum contact resistance. For all current circuits, auxiliary contacts are used which automatically short circuit the current transformer when the cover is removed.

Routine testing can be accomplished simply by removing the cover and substituting the properly connected test plug. Thereafter, normal connections are restored by replacing the cover.
