Neutral Disconnect & Installation Terminal Blocks

Bulletin 1492 Neutral Disconnect and Installation Terminal Blocks offer increased safety by requiring a tool to open or close a circuit. These blocks work with a series of feed-through circuits, ground circuits, and circuits with a direct connection to a bus bar. This bus bar runs the full length of the terminal blocks to a connection block that is mounted further down the rail for an isolated neutral connection.
