Product FAQs
8 answersWhat type of trip unit is included with the RKF36160U31A?
It includes a Micrologic 3.0 solid-state electronic trip unit. This provides adjustable long-time and instantaneous (LI) trip functions for precise overcurrent and short-circuit protection.
Is the RKF36160U31A rated for 100% continuous operation?
No, the RKF36160U31A is a standard 80% rated circuit breaker. It is designed to carry up to 80% of its 1600A rating continuously under normal operating conditions.
What wire gauge is accepted by the lugs on the RKF36160U31A?
The breaker accepts 3/0 AWG to 750 kcmil aluminum or copper wire. Due to the 1600A rating, multiple conductors per phase are required for proper installation.
What does the K in the RKF36160U31A part number signify?
The K designates the interrupting rating tier within the PowerPacT series. For this R-frame breaker, it indicates a short-circuit interrupting capacity of 65 kAIC at 480VAC.
Can I use the RKF36160U31A in an I-Line panelboard?
No, the F in the part number indicates this is a unit-mount, bolt-on circuit breaker designed for busbar or cable connections. It is not compatible with I-Line plug-on panelboards, which require an A mounting code.
What applications are suitable for the PowerPacT R-frame RKF36160U31A?
R-frame breakers are engineered for high-current distribution applications. They are commonly used in service entrances, large industrial facilities, critical power systems, and major infrastructure installations.
Does the RKF36160U31A provide ground-fault protection?
No, the included Micrologic 3.0 (U31A) trip unit only provides long-time and instantaneous (LI) protection. For equipment ground-fault protection, a Micrologic 6.0 trip unit would be required.
Are accessories field-installable on the RKF36160U31A?
Yes, the PowerPacT R-frame series supports a range of field-installable accessories, including shunt trips, undervoltage releases, and auxiliary switches. These accessories share commonality across the PowerPacT range.
