3UF18 current transformers
for overload protection
■ Overview
The 3UF1 8 current transformers are protection transformers and
are used for actuating overload relays. Protection transformers
are designed to ensure proportional current transfer up to a
multiple of the primary rated current. The 3UF18 current
transformers convert the maximum current of the corresponding
operating range into the standard signal 1 A secondary.

1) With or without box terminal.
2) Conductor cross-sections for box terminals, see 3TF6 8 and 3TF6 9
contactors in the section Contactors and Contactor Assemblies.
3) With max. conductor cross-section, a terminal cover for maintaining the
phase spacing is required.
