Eaton CHSPT1-208Y – Frequently Asked Questions

1) Can an Eaton CHSPT1 Type 1 surge protective device be installed on the line side of the main breaker?
Yes. The CHSPT1 series is a Type 1 device, which is what allows installation at the service entrance on either side of the service disconnect, unlike a Type 2 that must go on the load side. It mounts permanently, so it is a hard-wired install at the panel or meter socket, not a plug-in unit. Its 200 kA short circuit current rating lets it sit on high-capacity commercial services without exceeding the available fault current at the service.
2) Which Eaton CHSPT1 model do I order for a 208Y three-phase service versus a single-phase house panel?
Three orderable models cover the two service types. The CHSPT1-208Y is the three-phase wye version, rated 50 kA surge current. For single-phase, the CHSPT1MAX is the 45 kA option and the CHSPT1ULTRA is the 50 kA option. Phase configuration is the first thing to get right, so match the model to the service before comparing surge ratings.
3) Will an Eaton CHSPT1 surge protector work on a 120/240V single-phase or 120/208V three-phase system?
The maximum continuous operating voltage is 150 V line-to-neutral and 300 V line-to-line. That covers 120/208V wye three-phase and 120/240V single-phase service. It does not cover 277/480V systems, where the 277 V line-to-neutral exceeds the 150 V MCOV, so a 480V service needs a different device entirely.
4) Can an Eaton CHSPT1 surge protector be mounted outdoors next to the meter?
The enclosure is NEMA 4, which is rated against dust and water ingress, so outdoor mounting at the meter or on an exterior wall is within its rating. It ships as a permanently mounted device, so plan for conduit and a hard-wired connection rather than a cord.
5) Does the Eaton CHSPT1 meet UL 1449 for a service entrance surge device on a healthcare or school project spec?
UL 1449 certification is carried on the CHSPT1 series, to the 3rd Edition, as a Type 1 SPD. The values a spec reviewer normally asks for are on record: 20 kA nominal discharge current (In) at the 8x20us waveform, a voltage protection rating of 1000 V L-L and 600 V L-N, and a 200 kAIC interrupt rating.
6) What is the difference between the Eaton CHSPT1MAX and the CHSPT1ULTRA?
Both are single-phase Type 1 service entrance devices. The difference on record is surge current capacity: the CHSPT1MAX is 45 kA and the CHSPT1ULTRA is 50 kA. Everything else in the shared spec set, including the 20 kA nominal discharge current and NEMA 4 enclosure, is common to the family. For a home or small commercial service the MAX is the lower-capacity choice, the ULTRA the higher.
7) What does the 1000V voltage protection rating on the Eaton CHSPT1 mean for the equipment downstream?
Voltage protection rating is the let-through voltage the device clamps to during a surge: 1000 V line-to-line and 600 V line-to-neutral on the CHSPT1. That is the number to compare against the withstand rating of what you are protecting. A service entrance device like this handles the big lightning-driven transients; sensitive electronics on branch circuits are usually given a second, lower-VPR Type 2 or point-of-use device downstream rather than relying on the service entrance unit alone.
8) Is the Eaton CHSPT1 surge protector rated for a panel with high available fault current?
It carries a 200 kA short circuit current rating, listed as 200 kAIC. That covers service equipment well above what most commercial and all residential services see, so available fault current is rarely the limiting factor on this device. Confirm the SCCR you need from the utility fault study and compare against the 200 kA figure.
9) Should I put in a Type 1 service entrance SPD or a Type 2 panel surge protector?
A Type 1 device like the Eaton CHSPT1 is built to go at the service entrance and can be installed on the line side of the main disconnect, which is where whole-facility protection against lightning-driven and utility-side transients belongs. A Type 2 device has to be installed on the load side of the main and is what you use at a downstream distribution panel. Many facilities install both: the Type 1 at the service to take the large hit, a Type 2 or point-of-use device nearer the sensitive equipment. Note that this Eaton unit tops out at 150 V L-N, so it suits 120/240V and 120/208V services only.
10) How heavy is the Eaton CHSPT1 surge protector, and will it hang off a panel enclosure?
Product weight is .93 lb, so it is light enough to hang from a knockout on the side of a load center or meter socket without additional support. Mounting is permanent, so the fasteners and conduit connection carry it.
