BE1-32R, BE1-32R O/U

The BE1-32R Directional Overpower Relay and the BE1-32 O/U Directional

Over/Underpower Relay are solid-state devices which provide versatility

and control in protecting machines against reverse power flow,

underpower and overpower conditions.

ADVANTAGES

• Measures Real Power - El cos

• Wide variety of input configurations are available including single-phase

and three phase, 3 and 4 wire systems.

• Sensing ranges available from 0.5 to 6000 watts secondary.

• Instantaneous, definite and inverse timing characteristics available.

• Low input sensing and supply burdens.

• Qualified to the requirements of

-ANSI/IEEE C37.90.1-1989 and IEC 255 for fast transient and

surge withstand capability;

-IEC 255-5 for impulse.

• UL Recognized under Standard 508, UL File #E97033.
