Wanting more out of your basic feeder protection relay is reasonable and doesn’t mean you’ll end up with a more complex device. There’s a way to combine protection, monitoring, and control in a simple, compact package. And we’ve done it in the new SEL-851 Feeder Protection Relay.
During this technical presentation, you will learn how the SEL-851:
Helps prevent equipment damage with its comprehensive current, voltage, and frequency elements.
Increases safety and reduces incident energy with arc-flash detection that operates in as fast as 1 ms.
Easily integrates into systems using a wide range of communications protocols and ports.
Simplifies relay selection with its universal power supply, setting-selectable current inputs, and software-settable binary inputs.
