Basler Electric BE1‑32R Power Relay (B3E E1R A0N1F)
The Basler Electric BE1‑32R is a microprocessor‑based directional power relay designed to protect generators and feeders from reverse power and over‑power conditions. This relay is essential for preventing motoring of generators and detecting loss‑of‑grid situations. The specific style B3E E1R A0N1F offers flexible configuration for various system voltages and power ratings.
Utilising true RMS measurement, the BE1‑32R provides accurate power monitoring and fast tripping. Its programmable settings allow adaptation to different generator sizes and protection philosophies.
Key Features
Directional power detection (reverse and forward)
Adjustable trip power threshold and time delay
True RMS measurement for accuracy
Dual independent output contacts
Front‑panel display and keypad for local programming
RS‑232 communication port for remote access
Technical Specifications
AC voltage inputs: 100–480 VAC; current inputs: 1A or 5A; frequency: 50/60 Hz; power accuracy: ±2%; trip time: 0.1–10 s adjustable; operating temperature: -20°C to +70°C.
Applications
Commonly installed in generator paralleling systems, synchronous motor starters, and utility interface points. The BE1‑32R prevents damage due to reverse power flow, which can cause overheating and mechanical stress in prime movers.
