ABB MLA62 – Frequently Asked Questions

1) What does the ABB MLA62 main lug kit do, and when would I use it instead of a main breaker kit?
The MLA62 is a 600A oversize main lug kit for ABB lighting panelboards. Main lugs terminate the incoming feeders straight to the bus with no integral overcurrent device, so you use this when the panel already has an upstream disconnect and overcurrent protection feeding it. If the panel needs its own main disconnect at the enclosure, a main breaker kit is the part you want instead, not this one.
2) Will the ABB 600A main lug kit fit my Pro-Stock panelboard?
It is matched to ABB Pro-Stock merchandise panelboards and Pro-Stock breaker kits, and ABB references it against catalog number LA621236. It drops into those ABB panelboard platforms without non-standard modification. Check your panel interior against the LA621236 reference before ordering; it is not a universal lug kit for other manufacturers' panels.
3) Is the ABB MLA62 rated for a 600 amp feed?
600A is the rating, listed as 600A oversize, which is what lets it handle higher-capacity feed-through terminations on compatible ABB panelboards. Your conductors and upstream overcurrent device still have to be sized for the actual service.
4) Can I use the MLA62 for a feed-through panelboard setup?
Yes. It is a feed-through design, so it suits panel arrangements where power lands on the lugs and carries through to downstream equipment. That is a common arrangement on commercial lighting panel upgrades where one 600A feeder serves more than one panel.
5) Is this ABB part a circuit breaker or a lug?
It is a lug kit, not a breaker. The MLA62 provides the 600A main lug landing for the panelboard bus; it contains no overcurrent protection and will not trip on a fault. Protection has to come from the device feeding the panel.
6) How is the ABB MLA62 lug kit packaged, and what part number do I order?
Order it as ABB MLA62; it ships 1 each, so one order line is one kit. Distributors and contractors restocking a panel truck should count one kit per panel interior, not per phase.
7) Is the MLA62 suitable for a panelboard retrofit in an existing building?
That is one of its intended uses. ABB lists it for lighting panelboard upgrades, Pro-Stock panelboard servicing, and renovation and retrofit panel work, so it is a normal choice when converting or rebuilding an existing ABB panel interior to 600A main lug.
