Overview

The BE1-50 provides high-speed detection of phase and/or ground faults.

Optional output configuration allows the relay to be used as a phase

selective fault detector.

Features

• One relay can simultaneously monitor three phases plus neutral

currents.

• Pickup setting is continuously adjustable over a wide range.

• Pickup repeatability ±2% or 40 milliamperes, whichever is greater.

• Independent output contacts for each sensing element.

• High speed operation.

• Flexible power supply provides operation from station (dc) power or line

(ac) power.

Benefits

• Easily match system configuration with single-phase, two-phase

with-neutral, three-phase, and three-phase-with-neutral input

configurations.

• Minimized CT costs as a result of low sensing burden.

• Reduced battery load with low burden power supply.

• Accurate, repeatable, and reliable operation.

• Simple HMI provides clear and intuitive settings for easy

configuration.

• LED targets provide clear annunciation of status.

• Easily perform in-case system and device tests using test plugs.
