Voltage Disconnect Switch Block, CT Shorting Switches

 

The Model U3889 voltage disconnect switch block provides a means for disconnecting power monitoring equipment. Each disconnect switch 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. A popular choice for HVAC and building automation systems, BAS, 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.
