Product FAQs
6 answersHow does the PLA34120U64AE1 mount into a panelboard?
It utilizes an I-Line plug-on connection, which allows it to be installed directly onto the bus of compatible Square D I-Line panelboards and switchboards without the need for separate mounting hardware or cabled connections.
What do the U64A and E1 suffixes indicate in the PLA34120U64AE1 catalog number?
The U64A suffix designates the inclusion of a Micrologic 6.0P electronic trip unit with LSIG protection. The E1 suffix indicates that the breaker is equipped with Modbus communication capabilities for advanced power monitoring and network integration.
How adjustable is the trip unit on the PLA34120U64AE1?
The solid-state Micrologic electronic trip unit offers fully adjustable LSIG settings. This allows licensed electricians to precisely dial in the long-time, short-time, instantaneous, and ground-fault pickup and delay parameters to coordinate with other devices in the electrical system.
What are the wire size requirements for the lugs on this 1200A breaker?
The standard lugs on this P-Frame breaker accept four 3/0 AWG to 500 kcmil aluminum or copper conductors per phase.
Is external equipment required for ground-fault protection with this breaker?
No, the PLA34120U64AE1 features an integrated Micrologic electronic trip unit with built-in LSIG functions. This means equipment ground-fault protection is handled internally by the breaker without requiring a separate external ground-fault relay.
Is the PowerPacT P-Frame physically interchangeable with M-Frame breakers?
Yes, Square D PowerPacT P-Frame circuit breakers share the same dimensions, common mounting, bussing, cabling, and door cutouts as PowerPacT M-Frame breakers. However, when upgrading to a 1200A breaker like the PLA34120U64AE1, you must verify that your panelboard bus is rated for the increased amperage.
