Eaton EAT-CHSPT2ULTRA – Frequently Asked Questions

1) What does Type 2 mean on a surge protector, and where does it get installed?
Type 2 means the device is installed on the load side of the service disconnect, at the main panel, rather than ahead of the meter. The CHSPT2ULTRA is intended for service entrance installation so it protects the whole facility from one point, instead of protecting a single receptacle or piece of equipment the way a point-of-use strip does.
2) Can the Eaton CHSPT2ULTRA be mounted outdoors next to an exterior meter main?
Yes. The enclosure carries a NEMA 4 rating, which means it resists dust, dirt and water ingress, so it suits outdoor and weather-exposed mounting alongside an exterior panel. Many competing residential SPDs are indoor-only enclosures, so this is the point to check if the panel is on the outside wall.
3) Will a Square D Surgelogic EMD25 work in place of the Eaton CHSPT2ULTRA on a 120/240V single-phase panel?
No. The Eaton CHSPT2ULTRA is rated 120/240V single-phase for service entrance protection, while the Square D Surgelogic EMD25 is built for a 208Y/120V 3-phase 4-wire system. The two are matched to different service configurations, so the EMD25 is not a drop-in alternative on a single-phase 120/240V service. Stay with the CHSPT2ULTRA for single-phase residential and light commercial panels.
4) Is a 20kA surge rating enough for a house or small commercial building?
The CHSPT2ULTRA is rated for a 20kA nominal discharge current, which is the level it can repeatedly divert at the service entrance. That covers residential panels, commercial building mains, light industrial, multi-family and office or retail service. For large three-phase distribution gear, buyers typically step up to a panel-mounted unit like the Square D Surgelogic series.
5) Do I still need point-of-use surge strips if I install a panel surge protector?
A service entrance Type 2 device like the CHSPT2ULTRA handles surges coming in on the utility feed and diverts them away from the main panel before they reach branch circuits. It does not sit at the outlet, so sensitive electronics, network gear and A/V equipment are commonly still given a local plug-in protector as a second stage. The two do different jobs and are usually specified together.
6) Does a surge protective device replace the breaker, or does it need its own circuit?
It doesn't replace anything. The CHSPT2ULTRA is a surge protective device wired in parallel at the service entrance, so it sits alongside the existing overcurrent protection and diverts transients. It provides no overcurrent or short circuit protection of its own, and the panel's breakers still do that work.
7) For an outdoor, weather-exposed meter or panel location, is the Eaton CHSPT2ULTRA or the Square D Surgelogic EMD25 the better fit?
The Eaton CHSPT2ULTRA carries a NEMA 4 enclosure rating, which covers dust, dirt and water ingress for outdoor and weather-exposed mounting at the service entrance. The Square D Surgelogic EMD25 is catalogued as a 500kA 208Y/120V 3-phase 4-wire device and is aimed at three-phase service rather than single-phase 120/240V. For an exterior single-phase service entrance, the CHSPT2ULTRA is the one specified for that environment.
8) What is the Eaton part number to order for this whole-house surge protector?
The manufacturer part number is CHSPT2ULTRA from Eaton, a Type 2 surge protective device for 120/240V single-phase service. That is the number to quote when matching a spec or reordering to keep a portfolio of buildings standardized.
