Schneider LA36400 – Frequently Asked Questions

1) Will the Schneider LA36 breaker mount in an I-Line panelboard or switchboard?
Yes. The LA36 uses I-Line mounting, which is the plug-on stab configuration Schneider uses in I-Line panelboards and switchboards. It is not a bolt-on or DIN rail breaker, so it needs an I-Line interior with an open space that accepts the LA frame. Plan around a device that measures 11 inches high, 6 inches wide and 5.84 inches deep.
2) Which amperages of the Schneider LA36 3-pole breaker can I order?
The LA36 family is catalogued from 125A through 400A, and the two ordering points are LA36300 at 300A and LA36400 at 400A. Both are 3-pole thermal-magnetic devices on the same LA frame, so the case footprint does not change between them.
3) Can I use this breaker to feed a rooftop packaged HVAC unit or a refrigeration rack?
Yes, that is the intended use. The LA36 carries an HACR rating, which is the qualification an equipment nameplate calls for when it specifies "HACR type breaker" for heating, air conditioning and refrigeration loads. It is a 3-pole device wired ABC, so it lands a three-phase compressor or condenser feed directly.
4) What voltage system is the Schneider LA36 rated for?
The LA36 is a low voltage molded case breaker rated to 600V, which covers 480Y/277V and 600V three-phase distribution as well as lower 208V systems. Schneider's own catalog description for the 300A pole reads "3P 300A 600V, LA FA/LA MOLDED CASE CIRCUIT BREAKER".
5) Will a Schneider LA36 drop into an Eaton or Square D bolt-on panel?
No. The LA36 is an I-Line plug-on breaker and will not mount in a bolt-on load center interior. An Eaton BAB Series Quicklag breaker, for example, is a bolt-on thermal-magnetic device for Eaton panels and is not interchangeable with an I-Line frame in either direction. Match the breaker to the panelboard the manufacturer built it for.
6) Does a thermal-magnetic trip unit work for motor loads, or do I need electronic trip?
Thermal-magnetic is what the LA36 uses, and it is the standard choice for HVAC and motor feeders: the bimetal element handles sustained overload while the magnetic element clears short circuits fast. What it does not give you is field-adjustable long-time, short-time or ground-fault settings. If your drawing calls for adjustable trip curves or selective coordination bands, you need an electronic trip frame instead, not the LA36.
7) What lugs or terminals does the LA36 400A use?
The terminal reference on the LA36 is AL400LA, the aluminum lug assembly for the 400A LA frame. Confirm your conductor size falls inside that lug range before you cut cable, and note the breaker is a 3-wire configuration, so a neutral is not landed on the device.
8) Can the LA36 breaker be repaired or have its trip unit replaced in the field?
No. Schneider lists the LA36 as non-serviceable, so there are no field-replaceable internals and a tripped-and-failed unit gets swapped rather than rebuilt. Average service life is stated at 15 years, which is what facilities teams generally budget replacement cycles against.
9) Do I need a separate main breaker kit or accessories with the LA36?
The LA36 is a standard-function breaker, meaning no shunt trip, undervoltage release or auxiliary contacts are built in. If your sequence of operation needs remote tripping on loss of control power, that is a separate accessory in the frame's own accessory line, the way Eaton handles it with an undervoltage release for its NZM frames. Specify those at order time, because the LA36 itself is not field-serviceable after the fact.
10) I need a shunt or undervoltage trip on a 3-pole breaker - does the Eaton 10250T undervoltage release fit an LA36?
It does not. The Eaton 10250T undervoltage release is built for Eaton NZM series molded case breakers. The Schneider LA36 is a standard function option thermal-magnetic breaker and is listed as non-serviceable, so field accessory work is not part of its design. If the job calls for an undervoltage release, specify a breaker frame built to accept one rather than adding a release to the LA36.
11) I need documentation for a LEED or green building submittal on this breaker. What does Schneider publish?
The LA36 is designated a Green Premium product with environmental disclosure document ENVPEP1410004EN. Plastic parts are halogen free, the unit is mercury free, and packaging uses recycled cardboard with no single-use plastic. One caveat for European submittals: the reference contains Substances of Very High Concern above the REACH threshold, and RoHS status is compliant with exemptions.
12) Where is the Schneider LA36 circuit breaker manufactured?
Mexico. Schneider also flags the LA36 as traceable, which matters on government and institutional jobs where country of origin and unit traceability have to be documented on the submittal.
13) For a main breaker position, would the Eaton Pow-R-Xpress kit do what the LA36 does?
Different jobs. The Eaton Pow-R-Xpress convertible main circuit breaker kit is a kit for converting a panel to a main breaker configuration in Eaton Pow-R-stock equipment. The Schneider LA36 is a 3-pole 3-wire molded case breaker itself, 125A to 400A, I-Line mounted and HACR rated for heating, air conditioning and refrigeration loads. If the requirement is overcurrent protection on a three-phase HVAC feeder, the LA36 is the device; the Eaton kit is panel conversion hardware for an Eaton lineup.
