Square D RKF36200CU64AE1 – Frequently Asked Questions

1) Will the Square D PowerPacT R 2000A breaker land my 750 kcmil feeder cable?
Not directly. Model RKF36200CU64AE1 is a busbar-mount breaker with busbar connections on both the line and load side, so it bolts to bus, not to lugs out of the box. The stated terminal wire range is AWG 3/0 to 750 kcmil aluminum or copper at 68 N.m tightening torque, so cable termination requires the lug connection hardware rather than the busbar version supplied here.
2) Is 65kA enough interrupting capacity for a 600V switchboard service?
The R-Frame breaker is rated 65kA interrupting at 600VAC under UL 489, with a rated operational voltage of 600V AC 50/60Hz. Under IEC 60947-2 the rated service breaking capacity (Ics) is 65 kA at 240V AC and 55 kA at 380/415V AC. If your engineer's fault study puts available fault current at the breaker above 65kA at 600V, this frame will not satisfy the interrupting requirement and you need a higher breaking-capacity class.
3) What does the Micrologic 6.0P trip unit do that a thermal-magnetic breaker doesn't?
The 6.0P is an interchangeable electronic Power trip unit with LSIG protection: long-time, short-time, instantaneous, and ground fault. That gives you adjustable selective coordination between upstream and downstream devices, which a fixed thermal-magnetic unit cannot. It also carries Modbus communication for remote metering and monitoring from a building or plant power management system. The trip unit is interchangeable, so the protection package can be changed without replacing the frame.
4) Is this breaker approved for a project that requires UL and Canadian listings?
The PowerPacT R-Frame breaker is UL Listed, CSA Certified and NOM Certified, so it covers US, Canadian and Mexican approvals. It also complies with IEC 60947-2 and carries the CE mark, which matters on export-spec or IEC-referenced switchgear packages.
5) Do I need to derate this breaker for a high-altitude installation?
No derating is required below 6,561.68 ft (2,000 m). Between that and 13,123.36 ft (4,000 m) the breaker is usable with derating. Above 4,000 m it is outside the stated application range.
6) Will this breaker integrate with our existing Modbus power monitoring system?
The Micrologic 6.0P trip unit on this R-Frame breaker includes Modbus communication, so metering and trip data can be polled by a Modbus-capable power monitoring or BMS head end. That is the reason facilities standardizing on Modbus-based monitoring specify the 6.0P rather than a basic electronic trip.
7) Can maintenance trip this breaker by hand for lockout?
Yes. There is an integral push-to-trip button in the breaker cover, so the mechanism can be tripped manually at the unit for testing or before isolating the circuit.
8) Does this breaker meet RoHS and REACH requirements for our facility documentation?
It is compliant with the EU RoHS directive with exemptions, is mercury free and PVC free. On REACH, the reference is declared as containing Substances of Very High Concern above the threshold, which is the disclosure some institutional and government buyers need on file.
