BE1-24 General Information
MODEL AND STYLE NUMBER
Electrical characteristics and operational features included in a specific relay are defined by a combination
of letters and numbers which constitute the relay style number. The model number, BE1-24, designates the
relay as a Basler Electric Class 100 Volts Per Hertz Overexcitation Relay. The style number together with
the model number describe the features and options in a particular relay and appear on the front panel,
drawout cradle, and inside the case assembly.
Sample Style Number
Figure 1-3 illustrates how a style number determines and describes the relay features. For example, if the
style number were A1H-F1J-D1S2F, the relay would have the following features.
A
- Single-phase voltage sensing
1
- Sensing input range of 1.00 to 3.99 V/Hz
H
- Alarm output NC, trip output NO
F1
- Inverse square timing
J
- 125 Vdc power supply
D
- All targets current operated
1
- Instantaneous trip function included
S
- Push-to-energize-output pushbuttons
2
- Normally open auxiliary output contact
F
- Semi-flush mounting
