Thiết bị bảo vệ Relay Basler Electric BE1-50, 51, BE1-51, 27C, BE1-51 27R

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.
