Product Description

Siemens Reyrolle 7SR11 Nondirectional Overcurrent Protection Relay

Siemens Reyrolle 7SR11 Overcurrent Relay functionality allows highly flexible settings for current and time grading making it compatible with all types of overcurrent protection.

Reyrolle 7SR11 Relay Features

The relay functionality allows highly flexible settings for current and time grading making it compatible with all types of overcurrent protection.

The relays are available in single and four pole variants housed in E4 cases with the IEC 61850 protocol option housed in an E6 case. Integrated logic is provided to allow the optimal configuration of relay functionality with the relays analogue inputs and binary input/output circuits.

Protection, instrumentation and metering functionality is accessible via data comms channel(s). A front USB port for local PC connection or rear electrical RS485 port for remote connection is provided.
