  • Page 9: Section 1 • General Information

    During motor start-up, a low terminal voltage condition will inhibit the motor from reaching rated speed. The BE1-27 Undervoltage Relay will detect this low voltage condition and trip. Critical applications requiring continuous motor operation and applications where overloads during start-up may be maintained for a given time period, usually have a definite time or inverse time delay characteristic incorporated to avoid unnecessary tripping during low voltage dips.

  • Page 10: Transformer Protection

    BE1-27, BE1-59, and BE1-27/59 electrical characteristics and operational features are defined by a combination of letters and numbers that make up the style number. Model number BE1-27/59 designates the relay as a Basler Electric Under/Overvoltage Protective Relay. The model number, together with the style number, describes the options included in a specific device and appears on the front panel, draw-out cradle, and inside the case assembly.
