Shed non-priority loads Automatically
Main Drivers
“I want to switch to a more cost-effective contract with my electric utility. I can shed non-critical loads to make sure I stay within my utility rate block, but I can’t afford sudden power cuts.”
Solution in brief
Design your electrical system around Compact NSX circuit breakers
Compact NSX circuit breakers allow you to manage reflex load shedding: the automatic shedding of specific loads.
The Compact NSX circuit breaker with integrated Micrologic 5.2 E electronic trip unit sends the reflex load shedding command. The trip unit measures I, V, P and E, and produces the appropriate alarms. Each alarm is associated with a load shedding trigger setting and a deactivation setting, each with time delay. The reflex load shedding order is sent via the Compact NSX circuit breaker’s SDx output module.
