Industrial Protection

Feeder protection solutions offer comprehensive overcurrent and arc-flash protection capabilities suitable for all types of industrial- and commercial-scale facilities. 

Protect synchronous and induction motors with dedicated relays that include capabilities such as broken rotor bar detection, variable-frequency drive support, arc-flash detection, differential protection, and more.

Arc-flash protection relays work with low- and medium-voltage switchgear and easily coordinate with other devices in industrial- and commercial-scale facilities.

Protect buses and switchgear with high-speed differential fault detection, or expand your protection with features such as restricted earth fault, arc-flash, and overcurrent elements.

SEL devices protect valuable transformers in power generation systems, including generator step-up transformers.

SEL generator protection devices provide complete protection for all types and sizes of generators and prime movers.

Remote I/O modules transfer data from remote locations over fiber and expand the I/O of SEL relays, automation controllers, and other devices without modification to the control panel face.

SEL software helps you optimize the configuration of your device and visualize power system events.

Pre-engineered or custom panels and enclosures help keep costs low and increase system reliability when used for retrofit upgrades and new equipment installations.

Complete your project with power supplies, switches, panel-mount hardware, cables, and other accessories.
