Square D IMA42 – Frequently Asked Questions

1) Will a Square D Surgelogic IMA42 work on a 208Y/120V panel?
No. The IMA42 is built for 480Y/277V AC, 3-phase 4-wire systems, with a 320V maximum continuous operating voltage. Putting it on a 208Y/120V wye system is the wrong voltage class, and on a 480V delta (3-wire, no neutral) it is also the wrong configuration. Match the device to the system voltage and the 4-wire wye arrangement.
2) What size wire can I land on the Surgelogic IMA42 lugs?
The lug terminals on the IMA42 take conductors from AWG 10 up to AWG 2, so you can size the leads for the run length between the device and the panel bus without an adapter. Keep the leads short and straight for the best clamping performance.
3) Is the Surgelogic IMA42 a Type 1 or Type 2 SPD, and where can it be installed?
It is a UL Type 1 device, which means it is intended for integration into panelboards, switchboards, and custom-built OEM equipment on 480Y/277V 3-phase 4-wire systems. Type 1 is the classification you need when the device is connected on the line side of the service disconnect; it can also be used on the load side.
4) Does the Square D IMA42 meet UL 1449 for a spec that calls for a listed SPD?
It is Listed to UL 1449 5th Edition and compliant with CSA C22.2 No. 269.1, so it covers both US and Canadian submittal requirements on a 480Y/277V job.
5) Can an Eaton BRNSURGE10 be used instead of the Square D Surgelogic IMA42 on a 480Y/277V panelboard?
No. The Surgelogic IMA42 is rated 480Y/277V for a 3-phase, 4-wire distribution system, while the Eaton BRNSURGE10 is a two-pole BR Series surge protective device intended for BR loadcenters. A two-pole BR device does not cover the three phases plus neutral of a 480Y/277V wye system, so the two are not interchangeable. For a 480Y/277V 3-phase 4-wire panelboard or switchboard, the IMA42 is the correct form.
6) I only need surge protection on a single-phase 120/240V loadcenter - is the Surgelogic IMA42 overkill?
Yes, it is the wrong fit rather than simply oversized. The Surgelogic IMA42 is configured for 3-phase, 4-wire service at 480Y/277V. A single-phase loadcenter calls for a two-pole device such as the Eaton BRNSURGE10, a BR Series 10kA surge protective device. Match the SPD to the system voltage and number of poles at the panel you are protecting.
7) What do the 200 kA and 20 kA numbers on the Surgelogic IMA42 actually mean for my panel?
200 kA is the total surge current rating, the headline capacity for the transient events the device can absorb across its life. The 20 kA figure is the nominal discharge current (In), which is what UL 1449 uses to prove the device survives repeated 8/20 microsecond impulses at that level; it also carries a 20 kA impulse current (Iimp) rating. When an engineer specs a minimum kA per phase or per mode on a service entrance, the 200 kA rating is the number to compare against.
8) How do I know the Surgelogic IMA42 is still protecting after a strike?
There is a green LED for normal operation and a red status LED per phase that flags a fault, so a maintenance tech can tell at a glance whether a leg has failed. For anything unattended, the device ships with dry contacts and an alarm enable/disable switch so it can be tied into a BAS or remote monitoring point.
9) Can the Surgelogic IMA42 be added to an existing panelboard, or is it new-construction only?
Both. It is used in new construction and retrofit installations alike, wired into panelboards and switchboards through its lug terminals rather than requiring a factory-built slot. On a retrofit, the thing to confirm is that the existing gear is a 480Y/277V 3-phase 4-wire system and that there is room to mount the device with short leads.
10) What is the exact part number to order for the 480Y/277V Surgelogic SPD?
Order Square D model IMA42. That is the 200 kA, 480Y/277V 3-phase 4-wire UL Type 1 unit in the Surgelogic series, and it comes as a single configuration with no handing or option suffixes to specify.
11) What is the difference between the Square D Surgelogic IMA42 and the Eaton BRNSURGE10 surge protector?
They serve different parts of a building. The Eaton BRNSURGE10 is a BR Series two-pole device with a 10kA rating, sized for a residential or light commercial BR loadcenter. The Square D Surgelogic IMA42 is a 200kA, UL Type 1 device with a 20kA nominal discharge current, built into panelboards, switchboards, and OEM equipment on 480Y/277V 3-phase 4-wire systems, and it carries UL 1449 and CSA C22.2 No. 269.1 compliance along with per-phase status LEDs and dry contacts for remote monitoring.
12) What frequency and storage temperature is the Square D IMA42 rated for?
The device operates across a 47 to 63 Hz measurement range, which covers both 60 Hz North American and 50 Hz systems, and it can be stored between -50 and 80 degrees C. That storage range matters if the gear is staged in an unconditioned trailer or warehouse before install.
13) Is the Surgelogic IMA42 mercury free and RoHS compliant for a green building submittal?
Yes on both counts. The IMA42 is mercury free and RoHS compliant with exemptions, and it is packaged without single-use plastic. The packaging is not made with recycled cardboard, which is worth knowing if a project is tracking packaging criteria specifically. Country of origin is Mexico.
