Product FAQs
7 answersWhat switchboards and control centers are compatible with the RJF36160U44A?
This PowerPacT R-Frame breaker is designed for installation in Square D QED switchboards, Power-Style switchboards, and Model 6 Motor Control Centers.
What does the U44A suffix indicate in the RJF36160U44A catalog number?
The U44A suffix specifies that the breaker is equipped with a factory-installed Micrologic 6.0A electronic trip unit. This provides adjustable long-time, short-time, instantaneous, and ground-fault protection, along with an integrated ammeter.
Is this 1600A breaker rated for 100 percent continuous operation?
No, this is a standard 80 percent rated circuit breaker. Continuous loads should not exceed 1280A, which is 80 percent of its nominal rating, to comply with standard National Electrical Code requirements.
Does the RJF36160U44A provide ground-fault protection for equipment?
Yes. The included Micrologic 6.0A trip unit features an adjustable ground-fault trip function, allowing you to set specific pickup and delay parameters to protect electrical systems from low-level ground faults.
How is this R-Frame breaker mounted in an enclosure?
This specific model features a unit-mount configuration with busbar line and load connections. It is designed to be bolted directly to the bus system rather than using a plug-on installation.
Can the trip unit on this breaker be swapped in the field?
Yes. The Micrologic trip units on PowerPacT R-Frame breakers are field-interchangeable. This allows panel builders to upgrade or modify the trip functions without replacing the entire breaker frame.
How can I manually verify the mechanical operation of this breaker?
The breaker includes an integral push-to-trip button located on the front cover. Pressing this button manually trips the breaker to confirm the mechanical linkage is functioning properly.
