SEL-751/SEL-751A Feeder Protection Relay

, ,

The SEL-751 Feeder Protection Relay is ideal for directional overcurrent, fault location, arc-flash detection, and high-impedance fault detection applications. Flexible I/O options, easy mounting, and fast settings make the SEL-751 the right solution for industrial and utility feeder protection.

SEL-710-5/SEL-710 Motor Protection Relay

,

Protect asynchronous (induction) and synchronous motors with one SEL-710-5 Motor Protection Relay. New features include broken rotor bar detection and variable-frequency drive (VFD) support as well as options for arc-flash detection, differential protection, and synchronous motor protection.

SEL-849 Motor Management Relay

,

The SEL-849 Motor Management Relay offers current-, voltage-, and thermal-based motor protection; arc-flash detection; and power metering. It also provides all basic motor protection features, including protection for the following conditions:

SEL-4520 Arc-Flash Test Module

,

The SEL-4520 Arc-Flash Test Module provides a convenient way to test the operation of arc-flash detection relays installed in metal-clad and metal-enclosed switchgear. The SEL-4520 is used to test the SEL-751 and SEL-751A Feeder Protection Relays and other arc-flash detection relays that use light and overcurrent to sense an arc-flash event.
