BE1-50/51B-214/-215/-223/-225 General Information

9252000994 Rev N

Internal switches provide for selecting system operating frequencies of 50 or 60 Hz, instantaneous
element delays of 0.0 or 0.1 second, characteristic curve group selection for either GE IAC or ABB type
curves, and instantaneous or integrating reset characteristics. Switch location and description is provided
in Section 2.

Advantages

BE1-50/51B-214/-215/-223/-225 overcurrent relays have many advantages over other overcurrent relays.
The primary advantages are:

•

Time characteristics are defined by equations and graphs

•

Field selectable time characteristics

•

Very low burden extends the linear range of the CTs

•

Self powered from the sensed current

•

Continuous automatic calibration

BE1-50/51B-214/-215/-223/-225 overcurrent relays may be tested without removing the relay from the
case. Shorting contacts are provided for all current inputs when the connection plugs or relay chassis is
removed from the relay case.

SPECIFICATIONS

BE1-50/51B-214/-215/-223/-225 overcurrent relays have the following features and capabilities.

Current Sensing Input

Continuous Current:

14 Aac

BE1-50/51B-214/-215/-223

One Second Rating:

Dropout occurs at 95% of pickup value.

Dropout

0.0 to 9.9 seconds in 0.1 second steps.

Timing Range

The timing accuracy is the sum of

±

1 cycle,

±

2%. This accuracy applies to the range of 1.3 to 40 times tap

and is for a given measured multiple of tap. The measurement of the multiple of tap has an accuracy that
is the sum of

±
