Manufacturing for the SR products have been discontinued. As an alternative, please refer to the 8 Series product line.

The SR family of protection relays represents a multi-functional line of microprocessor products. By providing an economical system, protection, control, monitoring and metering, and both local and remote user interfaces in one assembly, the SR relays effectively eliminate the need for expensive discrete components.

In addition to traditional current and voltage inputs, the SR Family also offers several analog and digital inputs. These inputs provide the relay with vital information such as vibration, pressure, temperature, and breaker status. Several additional output relays are available for flexibility in creating custom protection schemes.
