currentphasefor electric motors

Dedicated numerical high-impedance circulating current relay providing unit protection for phase and earth fault detection. Why Reyrolle 7SR23? The Reyrolle 7SR23 DAD is a numeric high impedance circulating current relay with four current inputs. Use it as a unit protection to detect phase and earth faults in critical electrical infrastructure. This relay provides comprehensive unit protection for your electrical assets. It detects phase and earth faults to prevent damage and deliver operational continuity across busbars, transformers and motors. An integral CT supervision feature detects open circuits in CT secondary wiring for reliability. Integrated logic allows optimal configuration of relay input and output functionality, streamlining setup. Access protection, instrumentation and metering functionality via data comms channels, including a front fascia USB port and RS485 rear port, for flexible local and remote monitoring. Key benefits Protect your system Precisely detect phase and earth faults to protect your electrical systems. Integral CT supervision identifies open circuits in secondary wiring to prevent issues and maintain continuous, safe operation. Simplify installation and setup Design and install easily with standardized external components in an Epsilon case. Our integrated logic effectively configures relay input and output functionality to streamline setup and reduce complexity for your team. Maintain control remotely Access critical protection, instrumentation and metering data through various communication channels.
