About ASHIDA ADR245B-B-0-0-0-0-0-0-2-2-2-B PROTECTION RELAY

ASHIDA ADR245B-B-0-0-0-0-0-0-2-2-2-B PROTECTION

RELAYIncludes high impedance restricted earth fault protection (64R), inverse and definite time overcurrent, and phase sequence overvoltage protection (46, 47). Equipped with multi-shot auto-reclosing (4 shots), breaker failure detection (50BF), VT/CT supervision, and trip circuit supervision.

Comprehensive Protection and Advanced Features

The ADR245B relay provides multi-faceted protection with five elemental functions, including overcurrent and earth fault detection tailored for motors, transformers, and generators. Its microprocessor-driven logic guarantees accurate fault monitoring, rapid response time under 30 ms, and user-friendly operation. Essential features like event recording, self-diagnostics, and real-time value display empower operators to monitor and maintain electrical assets efficiently, minimizing downtime and improving safety.


Rugged Design and Flexible Integration

Housed in a solid polycarbonate and ABS body with an IP54-rated front panel, the ADR245B offers resilience against dust, humidity (up to 95% RH), and vibration. Its universal mounting options, wired terminal connections, and compatibility with a wide voltage range (110V/220V AC/DC) support seamless retrofitting or integration into both legacy and modern panels. Remote communication via RS485 MODBUS protocol further enables effortless supervisory control and monitoring from a central location.
