Square D MAM42 – Frequently Asked Questions

1) What does the Square D MAM42 surge module actually replace, and can I swap it without pulling the whole SPD?
The MAM42 is a field-serviceable replacement module for Square D Surgelogic IMA and EMA surge protective devices. After a surge event takes the protection out, you swap the module assembly instead of replacing the entire SPD, so the panelboard or switchboard stays in place. It restores the device to full listed performance.
2) Will the MAM42 module work on a 208Y/120V panel?
No. The MAM42 is built for 480Y/277V AC, 3-phase 4-wire systems, with a maximum continuous operating voltage (Uc) of 320V. Putting it on a 208Y/120V service is the wrong voltage class. Match the module to the voltage marked on the Surgelogic IMA or EMA unit it is going into.
3) How do I tell from the panel that the Surgelogic module still has protection left?
Each phase has its own pair of status LEDs on the module: green for normal operation, red to flag a fault. Walking the gear, a green on every phase means all three legs are still protected; any red means that phase has lost protection and the module needs changing.
4) Is the Square D MAM42 module UL listed for a facility spec that calls out UL 1449?
It is UL Listed to UL 1449 edition 5 and also carries CSA C22.2 No 269.1, so it covers both US and Canadian listing requirements for a Type-rated SPD component. That is the current edition of the standard most institutional and government specs reference.
5) Can an Eaton BRNSURGE10 be used in place of the Square D Surgelogic MAM42 module?
No. The Eaton BRNSURGE10 is a two-pole 10kA surge protective device in Eaton's BR Series, meaning it is a standalone device sized for a single-phase load center breaker space. The Square D Surgelogic MAM42 is a replacement module assembly that drops into an existing Surgelogic IMA or EMA surge protective device, rated 200kA at 480Y/277V on a 3-phase 4-wire system. One is a whole device for a residential-style BR panel, the other is a service part that restores an already-installed commercial or industrial SPD after a surge event. They are not interchangeable in either direction.
6) What wire size can I land on the terminals of this Surgelogic replacement module?
Terminals accept AWG 10 through AWG 2 conductors. That covers typical SPD lead sizing on commercial feeders, and it is the number to check against the existing leads before you order.
7) What is the difference between the 200kA surge rating and the 20kA number on this module?
The 200 kA figure is the surge current rating, the one-shot high-energy capacity of the module. The 20 kA is the nominal discharge current (In), the repetitive impulse level it is tested to withstand over multiple hits. Specs usually call out both, so make sure the drawing's In requirement is 20 kA or less before you substitute.
8) Is a 10kA surge device like the Eaton BRNSURGE10 enough, or do I need the 200kA Square D module?
They address different service points. The Eaton BRNSURGE10 carries a 10kA rating and is a two-pole BR Series device. The Square D Surgelogic MAM42 is rated 200kA surge current with a 20kA nominal discharge current, listed to UL 1449 edition 5 and CSA C22.2 No 269.1, and is intended for service entrance and panelboard or switchboard protection on commercial and industrial distribution equipment. Higher surge current capacity generally suits the higher exposure at a service entrance, while a smaller breaker-mounted device is typically applied downstream at a load center. Match the device to the point of application and the system voltage rather than to the kA number alone.
9) Can this module be used at high altitude, and what line frequency does it cover?
Operating altitude runs 0 to 12,000 ft, so mountain-site substations and mechanical penthouses are within range. Frequency measurement range is 47 to 63 Hz, which covers both 50 Hz and 60 Hz distribution.
10) Do I order the MAM42 by that part number, and where is it made?
MAM42 is the Square D manufacturer part number for the Surgelogic MA replacement module at 200kA, 480Y/277V. Country of origin is Mexico, which matters if you are filing domestic-content or procurement documentation on a public project.
11) Does the Surgelogic MA module contain mercury or fall under RoHS reporting?
Construction is mercury free, and the module is in scope for European RoHS as compliant with exemptions. It ships in packaging without single-use plastic. Those are the points that come up on sustainability-driven procurement and hospital or education facility submittals.
