JCA-0C Dimensions

Construction and Insulation

The core and coil are encapsulated in polyurethane resin within a
molded case. This material has excellent electrical and mechanical
properties over a wide temperature range, has very low water
absorption and is resistant to oil and a variety of chemicals.

Core and Coils

The core is made from high quality grain oriented silicon steel,
annealed under rigidly controlled factory conditions. The
secondary winding is made of heavy enameled copper wire. The
secondary windings are evenly distributed around the core for
maximum accuracy and resistance to stray fields from adjacent
conductors.

Terminals

Secondary terminals are tin plated brass, compression type. A

such a way as to prevent connection error. The terminal cover is
made of a clear plastic. Provision is made for sealing the cover.

Primary Bars

The primary terminals are tin plated copper bars.
3/8” bolts - 400:5 and below,
1/2” bolts - 500:5 and above.

Polarity

Primary and secondary polarity marks H1, H2 and X1, X2 are
molded into the case.

Nameplate

The nameplate is laser engraved aluminum. The nominal current
rating of the transformer is marked on the side in large numerals.

Maintenance

These transformers require no maintenance, other than
occasional cleaning, if installed where air contamination is severe.
