Micrologic 5/6 A or E Trip Units
Micrologic 5/6 A (Ammeter) or E (Energy) trip units can be used on PowerPact H-, J-, and L-frame
circuit breakers with performance levels D, G, J, or L. They all have a front display module. They offer
basic LSI protection (Micrologic 5 trip unit) or LSI and ground-fault protection G (Micrologic 6 trip unit).
They also offer measurement, alarm and energy values.
The capabilities of Micrologic 5/6 A and E trip units come into full play with the front display module.
When the two are connected using a simple cable with RJ45 connectors, the combination offers full
Power Meter capabilities and all the measurements required to monitor the electrical installation.
