• The primary and secondary terminals are No. 10–32 screws into 3/8” deep brass inserts and
• The core and coil assembly is encased in a thermoplastic shell and filled with resin.
• These transformers are designed for operation line-to-line. They may also be operated
• It is desirable to use an 8.0 amp BBS type or equal fuse in the secondary to protect
• With two exceptions these transformers are ANSI C57.13 group 1. Those marked * are
• Model designed specifically for 50Hz operation are available with reduced performance –
• Fuse blocks containing type KTK–R (class CC) fuses can be fitted.
• When primary fuses are requested, the ratings will be as given in the table below.
• This page contains a circle diagram for the estimation of the errors for other than rated
• When only one fuse is used, it must be connected into the line side (H1) terminal wiring.
