nVent CADDY SES40P120/240SP – Frequently Asked Questions

1) Will the nVent CADDY SES40P suppressor work on a 120/240V single-phase residential service?
That is exactly the service it is built for. The SES40P is rated 120/240V AC and configured for 1-phase, which matches standard US split-phase residential and light commercial power. For three-phase service (208Y/120 or 480Y/277), this is the wrong device.
2) Where in the electrical system does a service entrance suppressor like the SES40P get installed?
At the point of service entry, ahead of the downstream distribution. The SES40P intercepts transients at the service entrance so surges are clamped before they reach panelboards, load centers, and the branch circuits fed off them. It is used on new service installations and on service upgrades or retrofits of existing entrance equipment.
3) Can I use the SES40P on a 277/480V commercial service?
No. The SES40P is a 120/240V, single-phase device. A 277/480V or any three-phase service needs a suppressor rated for that system voltage and configuration; installing this one there would put it well beyond its voltage rating.
4) What is the amperage rating on the SES40P120/240SP suppressor?
40A. That sizes it for point-of-service-entry surge suppression ahead of residential and light commercial panelboards and load centers, not as a substitute for the service disconnect or main breaker.
5) Is the SES40P housing metal or plastic, and does that affect how I mount it?
The housing is thermoplastic, so it is a non-conductive enclosure rather than a metal one. Mounting at the service entrance does not rely on the housing for bonding, so the equipment grounding and neutral connections have to be made through the wiring terminations as with any suppressor.
6) What is the exact manufacturer part number for the nVent CADDY SES40P service entrance suppressor?
The MPN is SES40P120/240SP, in the nVent CADDY SES40P Series. The number reads out as the series, the 120/240V rating, and SP for single phase, which is useful when you are distinguishing it from other voltage and phase configurations in the SES lineup.
7) Does a service entrance suppressor replace the need for point-of-use surge strips inside the building?
Not entirely. The SES40P sits at the service entrance and knocks down transients coming in from the utility side before they reach the panel. Sensitive electronics on branch circuits are normally still protected locally, since surges can also originate inside the building downstream of the entrance device. The nVent CADDY SES platform covers both service entrance and point-of-use applications, so the two roles are treated as complementary.
