Chint BH-0.66 Current Transformer 100/5 to 4000/5 for Low Voltage Distribution Panel Power Measurement IEC60044-1
General
These current transformers are a comprehensive offer, ideally suited for use throughout entire low voltage field, from 40A to 4000A. They deliver at the secondary a current (0-5 A) proportional to the current measured at the primary; they can be used in combination with measurement devices (switchboard instrumentation, kilowatt-hour meters, power-monitoring units, etc.)
Primary current can be measured in two ways:
CT with let-through primary
CT with connection of primary by screw and nut
