BE3-25A

The BE3-25 series are synchronizing check relays, also known as paralleling relays. They are used to ensure that two AC supplies are synchronized. For a system to be synchronized, the frequency, phase angle, and voltage must be within preset limits. The BE3-25-****4 can monitor either utility mains bus bar and incoming generator, or two generators. The BE3-25-****4 offers user adjustment of the reset voltage from 10 to 30%. This voltage corresponds to 6 to 20 electrical degrees. The unit compares the input voltage and phase relationship of the bus bar to that of the generator. When the signal is within the preset limits, the relay energizes. The BE3-25-****5 operates as the BE3- 25-****4, but has the additional feature of a dead bus facility. This enables the relay to energize with a generator supply only, which is a common requirement when utility mains failure occurs.

Designate the Model Number followed by the complete Style Number.
Complete the Style Number by selecting one feature from each column of the Style Identification Chart and entering its designation, letter or number, in the appropriate square. Note: The description of a complete relay must include both Model Number and Style Number.
