BE1-64F relays are compatible with continuous field voltages up to 600 Vdc

and forcing voltages up to 750 Vdc for one minute. During reverse excitation

(negative forcing), BE1-64F relays will withstand up to 1.200 Vdc for one

minute.

Features

• BE1-64F models with connections to either the positive or negative

side of the exciter or main field of the machine are available.

• Detects field grounds on motors and generators.

• Two-level detection for pre-alarm and trip.

• Compact, draw-out case.

• Test function.

• Nonvolatile storage of trip target state.

Benefits

• Pre-alarm allows action to prevent a trip.

• Accurate, repeatable, and reliable operation.

• Simplified installation with no settings required.

• Retrofit into cutout made for ITE/BBC/ABB/GE field ground relays.
