DESCRIPTION

The Model U3889 Voltage Disconnect Switch Block provides

a means for disconnecting power monitoring equipment. It

provides isolation from line voltage and will short out and

disconnect current transformer secondaries, preventing

transformer damage that may occur when the circuit is

opened under load. One side of the switch is connected to

the circuits being measured; the other side of the switch is

connected to the power monitoring equipment. The black

plastic cover (209PF) is constructed so that all switches must

be in the closed position before the cover can be sealed.

FEATURES

• Provides voltage disconnect and CT shorting/

disconnect for power instrumentation

• Available in convenient metal screw cover enclosure

• Color-coded switch handles

• UL recognized
