Schweitzer SEL-751A Relay Fit for Switchgear Applications

Schweitzer Engineering Laboratories, Inc. (SEL) announces the availability of the SEL-751A Feeder Protection Relay. It has a compact size and panel-mount design, which SEL claims, is the right fit for switchgear applications and electro-mechanical retrofit. It comes with automation and communications features, including IEC 61850, MIRRORED BITS, Modbus, and other protocols.

The SEL-751A is able to limit available energy by coordinating feeder protection with motor and bus protection reduces arc-flash hazards. It can also automatically switch to instantaneous settings while performing maintenance and remotely access event data and other relay features with built-in communications.

"The SEL-751A is just the product we have been looking for to implement arc-flash protection across our system," said an electric utility protection engineer. "The small size and functionality make it perfect to replace electromechanical relays in a timely and cost-effective manner."
