Use arc-flash detection cables with SEL-751 and SEL-751A Relays to protect people and equipment from arc-flash events.
The SEL-751A offers industrial and utility feeder protection with flexible I/O options, easy retrofit, and fast setup and configuration. The SEL-751A provides complete feeder protection with overcurrent, voltage, and frequency elements. The SEL-751A remediates arc-flash hazards with arc-flash detection.
The SEL-4520 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 for sensing an arc-flash event.
