Current Transformer Terminal Block

Current transformer (CT) shorting terminal blocks provide a safe way to disconnect current transformer secondary circuits without open-circuiting the CT which would cause dangerous high voltages to develop.

// Specifications

Standard

IEC 61869-2 CT secondary

Function

Short-circuit CT before opening

Voltage

5V AC secondary nominal

Current

1A or 5A secondary rating

Use Case

Metering protection relay CT circuits

Safety

Never open CT secondary under load
