Basler Electric BE1-50/51, Self-Powered Time Overcurrent Relays

A single-phase self-powered, microprocessor-based time/instantaneous overcurrent

relay that provides cost-saving overload and fault protection for generators,

transformers, feeders, and motors. Available in multiple-rack, panel, and retrofit

mounting options.

See the Relay Upgrade Experts Chart in the Technical Resources tab below to

determine if a Basler relay can replace your older style relay.

Product Features & Benefits

• Accurate, repeatable, and reliable operation.

• No additional power source required since relays are self-powered from 50/60 Hz

systems. Available in five- or one-amp CT secondary models.

• Timings can be tailored to the application with multiple field-selectable curves.

• Flexible pickup is continuously adjustable over a wide range.

• Instantaneous protection can be set lower to provide more complete protection

with a design that minimizes transient overreach.

• Reduce arc flash hazards by applying a second independent instantaneous element

available.

• Models available to replicate decaying reset of electromechanical relay disks when

current drops to zero.

• Replace existing electromechanical relays with specifically-wired retrofit models.

• Reduce CT costs with low sensing and supply burdens.

• Reduce maintenance labor by eliminating the need for re-calibration.

• Testing is easy with drawout construction for all models and in-case testability for

most models.
