Oil-immersed
load break switches.

It makes or breaks load current within its specified duty in an oil-filled transformer assembly. It is not a substitute for a circuit breaker or coordinated fault protection. Review the selected model’s electrical duty and installation drawing before approval.

The two-position family supports ON/OFF arrangements. The four-position family is a starting point for sectionalizing and transfer arrangements with multiple circuit positions. The required position diagram and transition sequence determine the model, not the position count alone.

Download the two-position or four-position PDF catalogue below. For project approval, request the exact model datasheet, dimensional drawing, position diagram and applicable test records from ZEEYI. Family information is a preliminary reference, not an approval drawing.

Send your voltage class, current, frequency, phase arrangement, circuit diagram, mounting drawing, quantity, destination and target date. Identify any required test documents. ZEEYI can then review the configuration and quotation requirements.
